Thru-hiking: how to plan and finish your first long trail

A thru-hike is the longest walk most people will ever take: one trail, end to end, in a single season, carrying everything you need between towns. It is also a project most people do not finish. On the Appalachian Trail, only about one in three who set out to walk the whole thing reach the other end. The ones who make it are rarely the fittest people on the trail. They are the ones who picked a trail that suited them, started slowly enough to let their bodies adapt, kept their feet and stomachs working, managed their money and their towns, and had a plan for the bad days before the bad days came.

This guide is for your first long trail. It covers choosing a trail in the United States or Canada, direction and timing, permits and border paperwork, the real costs, base weight and the shakedown trip, shoes and feet, resupply, the injuries and illnesses that end hikes, the hazards long trails add, safety in towns and on your own, trail culture, and the mental game. Where we already have a deep guide on a topic, such as pack fit, pacing, or water treatment, we point you to it rather than repeat it.

What a thru-hike is, and why most attempts end early

A thru-hike means walking an entire long-distance trail, end to end, in one continuous push. The Appalachian Trail Conservancy counts a hike as a thru-hike when it is completed within twelve months. A section hike covers the same trail in pieces, over several seasons or many years. A flip-flop is a thru-hike done in two legs: start somewhere in the middle, walk to one end, then return to your starting point and walk to the other end. The three big American trails, the Appalachian, the Pacific Crest and the Continental Divide, together make up what hikers call the Triple Crown.

Completion rates are lower than most first-timers expect. The Appalachian Trail Conservancy puts the overall rate at about one in three, and its reported figures for 2025 show 25% of northbound starters (550 of 2,187) and 31% of southbound starters finishing. Surveys of Pacific Crest Trail hikers report much higher finish rates, but those surveys are filled in by people who choose to respond, and hikers who finished are far more likely to bother, so treat them as a ceiling rather than a forecast.

The trail itself is rarely what stops people. Hikes end because of overuse injuries, illness, running out of money, a family emergency, loneliness, or the slow erosion of motivation somewhere in the long middle. The Conservancy’s own summary is blunt: most hikers find that finishing depends more on mental resilience than on physical strength. Almost everything in this guide is about removing one of those reasons before it can find you.

Choosing your first long trail

You do not have to start with a five-month trail. A two to six week trail teaches you nearly everything a long trail will: daily mileage, resupply, foot care, food, weather, and what it feels like to wake up and walk again on day nineteen. It does that for a fraction of the time off, money, and risk. Plenty of people who go on to finish the big trails walked a shorter one first, and plenty of people find a month-long trail is exactly the experience they wanted.

Long trails measured in weeks

The Long Trail, Vermont. 272 miles (438 km) along the Green Mountains from the Massachusetts border to Canada. The Green Mountain Club says an end-to-end hike averages 21 to 25 days. July through September is the best window; high-elevation hiking is discouraged during spring mud season. Expect rocks, roots, mud and steep climbs, especially in the northern half, so plan lower daily miles than the distance suggests.

The Colorado Trail, Colorado. 486 miles (782 km) from Denver to Durango on the standard route, most of it above 10,000 feet (3,000 m). Most thru-hikers take four to six weeks, and the practical season for the whole trail is roughly July to September. It is a superb first long trail with two serious caveats: altitude, and afternoon thunderstorms on long stretches above tree line.

The John Muir Trail, California. About 211 miles (340 km) from Yosemite Valley to the summit of Mount Whitney, at 14,505 feet (4,421 m) the highest point in the contiguous United States. Most hikers take about three weeks, usually between July and September. The scenery is extraordinary and so is the demand: Yosemite caps John Muir Trail hikers leaving the park over Donohue Pass at 45 a day, so the permit is the hardest part.

The East Coast Trail, Newfoundland. 209 miles (336 km) of linked coastal paths and community walks on the Avalon Peninsula, from Topsail Beach to Cappahayden. Hikers commonly take 12 to 20 days, and the season runs from late June to early October. There is no permit, the towns along the way make resupply easy, and the sea cliffs and coves are some of the finest hiking in the country.

The Sunshine Coast Trail, British Columbia. 112 miles (180 km) from Sarah Point in Desolation Sound to Saltery Bay, and the longest hut-to-hut trail in Canada. More than a dozen public huts sit along the route, most of them free and first-come, which makes it an unusually gentle introduction to long-distance travel.

The Bruce Trail, Ontario. 560 miles (900 km) of main trail along the Niagara Escarpment from Queenston to Tobermory. Roughly half of it crosses private land by agreement with landowners, and the Bruce Trail Conservancy is clear that an end-to-end hike by camping alone is not possible because designated sites are too few and far apart. Plan it as a mix of campsites and roofed accommodation.

The long ones

The Appalachian Trail, Georgia to Maine. More than 2,190 miles (3,525 km). Most thru-hikers take five to seven months, and the average is just under six. It has the most support of any long trail, with shelters, hostels and towns close together, and it is the most crowded. It is also relentlessly steep, rocky and humid, which surprises people who assume the East must be easier than the West.

The Pacific Crest Trail, Mexico to Canada. 2,650 miles (4,265 km) through California, Oregon and Washington. Hikers who responded to a 2025 survey averaged about five months. The trail was built for horses and pack stock, so its grades are gentler than the Appalachian Trail’s, but it asks more of your judgement: desert water carries, High Sierra snow and river fords, and a wildfire season that closes sections every year.

The Continental Divide Trail, New Mexico to Montana. About 3,100 miles (5,000 km) as officially measured, though most hikers walk less using alternate routes. The Continental Divide Trail Coalition says a thru-hike typically takes five to seven months. It is the most remote of the three, with more navigation, more route choices, long stretches at high elevation in Colorado, and grizzly country in the north. It is rarely a sensible first long trail.

The Great Divide Trail, Alberta and British Columbia. 680 miles (1,095 km) along the Continental Divide from Waterton Lakes to Kakwa Lake, through five national parks. The Great Divide Trail Association plans on about eight weeks, in a short season that runs from late June or early July into mid-September. Only parts of the route are officially signed; elsewhere it is an unmarked cross-country route where you navigate for yourself, with deep, fast glacial streams, prime grizzly habitat, and permits you must reserve in advance. It is one of the hardest long routes in North America and not a first thru-hike.

How to choose

• Time available. Be honest about the window between the snow melting and the snow returning, then subtract the rest days you will actually take.
• Support versus solitude. Frequent towns and shelters make a first long trail forgiving. Remote trails punish mistakes in food, navigation and gear.
• Your specific weak spot. Nervous about navigation? Start with a well-marked trail. Worried about altitude or heat? Pick a trail that avoids them, or a direction and season that does.
• Getting home. A trail that ends near a bus, train or airport is easier to leave early, and easier to leave at the end.

Direction and timing

Direction on a long trail is not a matter of taste. It is dictated by snow at one end, heat or cold at the other, and how long it takes you to walk between them.

Northbound (often written NOBO) is the most common choice on both the Appalachian and Pacific Crest trails, because it follows spring north. Southbound (SOBO) starts later, is quieter, and usually begins with the hardest terrain: on the Appalachian Trail that means Katahdin and Maine’s remote 100-Mile Wilderness, with fewer resupply points early on, so the Conservancy suggests it for experienced and fit hikers. Flip-flops are the Conservancy’s answer to crowding at the Georgia start. Its guidance for a common version, starting at Harpers Ferry, West Virginia, is not to head north from there before about April 15, and to allow six to eight weeks or more to reach full trail fitness.

Every long trail has a hard edge somewhere in the calendar:

• Appalachian Trail. Baxter State Park strongly recommends that northbound hikers summit Katahdin before October 15, when shoulder-season closures begin. Work backwards from that date with a realistic daily mileage.
• Pacific Crest Trail. Start too early and you reach the High Sierra while it is still buried in snow and the creeks are running high. Start too late and you race autumn storms in Washington’s North Cascades. In the 2025 survey, northbound hikers who were happy with their timing started around mid-April.
• Continental Divide Trail. The same squeeze, harder: arrive early and Colorado’s high country is still under snow; arrive late and early-autumn snow can shut down northern Montana.
• Great Divide Trail. Snowmelt sets a start in late June or early July, and September storms close the window, which is why its season is described as deceptively short.

Snow years vary enormously, so check the current snowpack and the managing association’s conditions page before you lock in a date rather than relying on last year’s timing. Our guide to reading backcountry weather explains how mountain weather builds and what a forecast can and cannot tell you.

Permits, borders, and paperwork

Permits on long trails range from one document covering the whole walk to a patchwork of park-by-park rules. Rules change often, so treat everything below as a map of what to look for and confirm the details with the managing agency.

Pacific Crest Trail. The interagency long-distance permit, issued through the Pacific Crest Trail Association, covers trips of 500 miles (800 km) or more along the trail. Applications open in late autumn and winter for the following season, through an online queue that assigns your place at random, and the number of daily starts from the southern terminus is capped. Only about half of 2025 survey respondents got the start date they wanted, so have a second and third choice ready. You also need a separate California campfire permit to use a stove anywhere in the state, and bear canisters are required through parts of the High Sierra, including Yosemite and sections of Sequoia and Kings Canyon, so in practice you carry one through the Sierra.

Appalachian Trail. There is no single permit. The Conservancy’s permit page lists them: a thru-hiker permit for Great Smoky Mountains National Park (for hikers who begin and end at least 50 miles (80 km) outside the park), a backcountry permit for Shenandoah National Park, campsite fees in the White Mountains, and a free Long Distance Hiker Permit for Baxter State Park, issued in person at Katahdin Stream Campground and capped at 3,150 a year. The Conservancy also runs a free voluntary start-date registration so hikers can spread themselves out.

Continental Divide Trail. Expect separate permits for backcountry camping in Glacier and Yellowstone national parks, a recreation permit to cross the Blackfeet Nation, and rules for Rocky Mountain National Park if you camp there, plus free self-issued wilderness permits at trailhead kiosks.

Great Divide Trail. The association puts it plainly: you cannot just show up and hike the whole trail without permits. National park backcountry campsites must be reserved with Parks Canada and can be competitive, and food must be stored in bear-resistant containers at Parks Canada random camping areas.

Canadians hiking in the United States. A long trail means a stay of 30 days or more, and since April 11, 2025, Canadians aged 14 and over staying that long must be registered with the US government. Travellers who fly in are normally issued an electronic Form I-94, which counts as registration. Travellers who cross by land often are not, and then must register online with US Citizenship and Immigration Services. Check your status on the CBP I-94 website after you arrive. Hikers from visa-waiver countries are limited to 90 days, which is not enough for the long trails, so many apply for a B-2 visitor visa instead.

Health coverage. Provincial health plans cover very little of the cost of treatment in the United States, and even at home a helicopter evacuation or a long hospital stay can be expensive. Whatever your nationality, buy travel medical insurance that explicitly covers hiking, search and rescue, and evacuation, and carry the policy details with your permits.

Time off and money

The cost of a thru-hike has three parts: the gear you buy before you start, what you spend on the trail, and the income you do not earn while you are out. The third is usually the largest, and it is the one people forget to plan for. In the 2025 Pacific Crest Trail survey, more than a third of respondents had quit a job to hike.

On the trail itself, towns eat the budget, not the trail. A day of walking costs very little beyond the food you carry. A zero day in town, with a motel room, restaurant meals, laundry and a resupply, can cost as much as a week of walking. The single biggest lever on the total is how many nights you spend under a roof.

Budget for the things people forget:

• Replacement shoes, several pairs of them on a long trail.
• Gear that breaks or fails in the first month and has to be replaced in whatever town you are in.
• Postage for mail drops and a bounce box.
• Getting to the start, getting home from the end, and getting home early if you have to leave.
• The weeks after the trail before you are earning again.

Keep an emergency fund you do not touch for town days. Running out of money is one of the most common and most avoidable ways a hike ends.

Base weight and the shakedown trip

Base weight is everything in your pack except food, water and fuel. Our guide to fitting and packing a backpack covers the common bands (under 10 pounds (4.5 kg) is usually called ultralight) and how to fit the pack you choose. On a weekend trip a few extra pounds are an annoyance. On a long trail you lift them on every step for months, and the extra load lands on the same feet, knees and tendons that overuse injuries target.

Get the weight out of the right places. The big three, meaning your pack, your shelter and your sleep system, are where most of the weight lives and where most of the savings are. Do not save weight by leaving out the things that keep you alive: a real rain shell, a warm insulating layer, first aid, navigation, a way to call for help, and a way to treat water. Our guide to layering and fabrics covers the clothing system, and staying warm through a cold night covers the sleep system.

Useful long-trail choices from our reviews include the Therm-a-Rest NeoAir XLite NXT sleeping pad (or the Z Lite Sol foam pad, which cannot puncture), a packable down jacket such as the Ghost Whisperer, trekking poles such as the Black Diamond Distance Carbon FLZ (see every use for trekking poles, including pitching a shelter), and a light stove such as the MSR PocketRocket 2. Plenty of thru-hikers go stoveless and cold-soak their meals; try it on a shakedown before you mail your stove home.

The shakedown trip is the most valuable thing you can do before you start. Take three to five nights with exactly the kit, food and water system you plan to use, in the worst weather you can safely find. Weigh everything before you go. When you get home, sort every item into three piles: used and needed, not used but needed for safety, and not used. The third pile stays home.

Expect to keep adjusting in the first few weeks. Many long-distance hikers mail home gear they thought they needed, and swap items as the terrain and seasons change. That is normal, and it is why a bounce box (see resupply, below) exists.

Shoes and feet over a thousand miles

Feet are where a long hike most often starts to go wrong, and foot problems travel upward: a sore foot changes your stride, and a changed stride loads your shins, knees and hips. In a survey of 280 Appalachian Trail long-distance hikers published in 2003, 64% reported blisters and 36% reported acute joint pain. Our guide to hiking all day explains blister mechanics and prevention, and wound care covers treating one that has opened.

Trail runners or boots. Most hikers on the major long trails now walk in trail-running shoes. They are lighter, they dry quickly after a ford or a wet day, and they break in immediately. They also wear out faster, protect less against rocks, and give less support under a heavy pack. Boots still make sense for heavy loads, snow travel, rough off-trail routes, or ankles with a history. Whatever you choose, choose it on a shakedown trip, not in a store.

Your feet will change. Feet swell during long days, and over weeks on a trail many hikers find they need half a size or more larger than they started with. Some find the change is permanent. Buy with room in the toe box, and do not be surprised if the second pair is a size up from the first.

Plan to replace shoes. A common guideline for running-shoe midsoles is 300 to 500 miles (480 to 800 km), after which the cushioning stops absorbing shock well. On a trail the length of the Appalachian that means somewhere around four to seven pairs. New aches in your feet, shins or knees are often the first sign a pair is finished, well before the uppers look worn out. Small-town outfitters may not stock your size, so many hikers mail replacement pairs ahead.

Socks and daily care. Carry a dedicated dry pair for sleeping. Take your shoes and socks off at long breaks to let your feet dry and cool. Treat a hot spot the moment you feel it, not at the next break. Wool socks with a lifetime guarantee, such as Darn Tough’s women’s and men’s Light Hiker, suit a long trail because you will wear through several pairs.

Resupply: towns, boxes, or both

You will not carry food for a whole trail. You carry enough to reach the next place you can get more, usually somewhere between a few days and a week away. How you get that food is the core logistics decision of a thru-hike.

Buying as you go. You shop in trail towns as you reach them. It is flexible, needs almost no pre-planning, lets you eat what you actually crave, and puts money into the communities that support the trail. The downside is selection: some stops have only a gas station or a small general store, which is hard on specific diets and dull after a few weeks.

Mail drops. You pack boxes of food and supplies at home and have someone mail them to post offices, hostels or businesses along the route. You control exactly what you eat, which matters for allergies and dietary needs. In exchange, you are tied to post office hours (small offices often close for lunch and on weekends), you pay postage, and food you packed months earlier may be food you are sick of by the time you reach it. In the United States, post offices accept packages addressed to you care of General Delivery, but they hold them for a limited time, so time the arrival and call ahead. Hostels and outfitters that accept hiker packages usually say so, and many ask that you check first.

The hybrid. Most hikers end up doing both: buying in towns with a real grocery store and mailing boxes to places with little or nothing. Remote routes lean heavily on boxes. The Great Divide Trail Association notes only three places on that route with a full resupply, so most GDT hikers send boxes every four to nine days.

The bounce box. A box of things you need occasionally but not every day, such as a charger, clippers, extra batteries, bulk foot tape, or winter layers for a later section, that you mail ahead to yourself unopened from town to town.

For choosing trail food, the calorie-per-ounce framework in what food to bring applies directly. Aim for dense food at 100 calories per ounce (about 350 per 100 g) or better, and remember water is the heaviest thing you carry: every quart (0.95 L) adds about 2 pounds (0.95 kg).

Town discipline. A short day into town, resupply, shower, laundry, a big meal, and a short day out, sometimes called a nero, gives you most of the benefit of a zero day at a fraction of the cost in money and momentum.

The first month: building trail legs without breaking

Your heart and lungs adapt to long days within a couple of weeks. Your tendons, ligaments and bones adapt far more slowly, and that mismatch is the trap. By week two you feel strong enough to double your mileage, and your Achilles tendons have not been consulted. The Conservancy says most hikers develop real trail legs within a month or two. Until then, your fitness is ahead of your structure.

Train with a loaded pack on hills. The best preparation is not the gym and not flat running. It is walking uphill and downhill with weight on your back, ideally on back-to-back long days so your body learns to recover overnight. Three quarters of the 2025 Pacific Crest Trail survey respondents trained before they started.

Start short and stay short. For the first two weeks, keep your days well below what you think you can do, often somewhere around 8 to 12 miles (13 to 19 km) depending on terrain, and build gradually. A common story behind an early injury is keeping pace with someone stronger in week one.

Know the overuse injuries. The ones that end long hikes are shin splints, tendon pain (Achilles especially), plantar fasciitis in the arch and heel, knee pain on long descents, and stress fractures in the feet and lower legs. Most of them start as a niggle you can manage with a shorter day, a zero, better shoes, or a change in stride. Trekking poles take real load off your knees on descents, and our guide to why the descent does the damage explains how to walk downhill well. If an injury needs splinting or evacuating, see splinting sprains and fractures.

Go easy on the ibuprofen. Taking it every morning to walk through pain hides the warning signs your body is sending, and anti-inflammatories are hard on the kidneys when you are working hard in heat and short on water. Use them to get through a bad night, not to fuel a bigger day.

Water, but not too much. Long, hot days tempt people to drink by the litre whether they are thirsty or not, and that can cause exercise-associated hyponatremia, a dangerous drop in blood sodium. Our guide to hydration on long days covers how to drink to thirst and watch your urine colour instead of chasing a quota.

Hiker hunger and eating enough

Long days with a pack burn a lot of energy. A registered dietitian’s estimate for backpacking puts most hikers somewhere between 2,800 and more than 6,000 calories a day, depending on body size, distance, terrain and climate. Almost nobody carries that much food, so most thru-hikers lose weight, and the gap gets wider in cold weather and at altitude.

Hiker hunger is real, and it is late. For the first weeks many hikers are not especially hungry, which makes it easy to under-eat. Then, for many people a few weeks in, appetite arrives all at once and does not leave. Eat on a schedule early, before you feel you need to, and plan your later resupplies around a bigger appetite than you have in week one.

Eat for the long haul, not just for the next climb. What drives a thru-hiker’s food bag is calories for the weight, because every ounce of it goes up the next climb on your back. That is why candy bars, chips and pastries earn their place: they keep, they need no cooking, and they carry a lot of energy for what they weigh. The problem with a convenience-store resupply is not what is on the shelf, it is what is missing from it. Protein is the first thing to go short, so buy it on purpose: tuna or salmon packets, jerky, nuts and nut butter, hard cheese, cured sausage. Fat carries more than twice the energy per gram that carbohydrate does, which is why olive oil, nut butter and powdered milk give you the most calories for the least weight. Use town stops for what you cannot carry at all, meaning fruit, vegetables and a real cooked meal. Losing weight fast also means losing muscle, and muscle is what carries you.

A note for women. Missed or irregular periods on a long trail are a recognized sign of low energy availability, where the body is not getting enough fuel for the work it is doing. It is not a sign of fitness. Eat more, and if it continues after the trail, see a doctor.

However you store food, store it properly. Bears, rodents and other animals learn fast along popular trails. See protecting your food from animals for canisters, hangs and camp layout; the BearVault BV500 is the canister we recommend for places that require one.

Staying healthy: water, hands, and ticks

The same 2003 survey of Appalachian Trail hikers found diarrhea in 56% of them and called it the most common illness limiting long-distance hikers. Two habits made the biggest difference. Hikers who frequently drank untreated water had roughly 7.7 times the odds of diarrhea, and those who practised good hygiene, meaning handwashing and cleaning their cookware, cut their odds roughly in half.

Treat every water source, including the clear spring everyone else is drinking straight from. Our full guide to purifying water in the backcountry explains the options. A squeeze filter such as the Sawyer Squeeze is the long-trail standard, with Potable Aqua tablets as a backup when a filter freezes, clogs or breaks.

Norovirus travels the trail with the hikers. It spreads fast in crowded shelters, hostels and privies, through shared food bags and bottles, and on surfaces everyone touches. Outbreaks along the Appalachian Trail have prompted park warnings in recent seasons. The Conservancy’s norovirus guidance is worth reading in full before you go.

Keep hygiene boring and daily. Wash your hands before you eat and after the privy, keep your own spoon and bottle, and clean your pot. Our guide to backcountry hygiene covers the routine, and human waste in the backcountry covers catholes and packing out where the trail requires it. Carry soap and use it at least 200 feet (60 m) from water.

Ticks. In the same survey, 24% of hikers reported tick bites, and Lyme disease was the most common vector-borne illness. The Appalachian Trail runs through some of the highest Lyme country in North America. Wear permethrin-treated clothing, check yourself every evening, and remove ticks promptly. Our guide to ticks and the diseases they carry explains removal and the symptoms to watch for afterwards.

Heat and altitude. Desert stretches bring heat illness, covered in hiking safely in the heat and heat illness. The Colorado Trail, the John Muir Trail and the Continental Divide Trail spend long stretches high enough to cause altitude sickness, so give yourself time to acclimatize before the big climbs.

The hazards long trails add

A long trail crosses more terrain, more weather and more months than any single trip, so it collects hazards that a weekend never meets.

Snow and river fords. In a big snow year, the High Sierra on the Pacific Crest Trail and the high passes of the Continental Divide Trail mean steep snow slopes and creeks swollen by snowmelt. Snowmelt creeks usually run lowest in the early morning and highest in the afternoon, so plan crossings early. Read crossing a river safely before you go, and crossing difficult terrain for steep snow. Traction such as Kahtoola MICROspikes helps on firm snow, but it is not an ice axe, and an ice axe is only useful if you have practised self-arrest.

Wildfire and smoke. Fire closures are now a normal part of a western thru-hike. In the 2025 Pacific Crest Trail survey, only about 16% of respondents described their walk as truly continuous, and a quarter said it was continuous apart from fire closures. In 2026 the lightning-caused Ptarmigan Fire closed the final stretch from Harts Pass to the northern terminus from late July. Closures are legal orders, not suggestions. Check InciWeb and the trail association’s closures page before each section, know your exit routes, and treat heavy smoke as a reason to slow down or leave.

Desert water. Water sources in the desert can be many miles apart, and they change year to year. Carry enough capacity for the longest dry stretch plus a margin, use current water reports, and never plan on a water cache or trail magic being there. A collapsible container such as the CNOC Vecto adds capacity for almost no weight. Our guide to finding water covers what to do when a source is dry.

Lightning above tree line. Summer afternoon thunderstorms are the daily rhythm in Colorado and much of the Rockies. Start early, be over the exposed passes and ridges by early afternoon, and know what to do when you are caught. See lightning safety in the backcountry.

Bears. Black bears live along almost every long trail. Grizzlies live along the northern Continental Divide Trail and throughout the Great Divide Trail. In grizzly country, carry bear spray where you can reach it in a second, not in the pack. See handling wildlife encounters and our review of SABRE Frontiersman bear spray.

Late-season cold and hunting season. Late northbounders in Washington, Montana or Maine, and early southbounders anywhere high, can meet snow and cold rain that turn a tired, underfed hiker hypothermic quickly. Know the signs in our hypothermia guide. In autumn, many long trails pass through public hunting land, so wear blaze orange on yourself and your pack.

Towns, hitching, and hiking alone

Many thru-hikers start alone. In the 2025 Pacific Crest Trail survey, three quarters of respondents began their hike solo, and more than a third of respondents were women. On popular trails, starting alone rarely means walking alone for long, but on remote routes and outside the main season, it can.

Carry a way to call for help. Cell coverage on long trails is patchy at best. A satellite messenger such as the Garmin inReach Mini 2 lets you send an SOS and check in by text, and a personal locator beacon such as the ACR ResQLink does the SOS part without a subscription. Our guide to signaling for rescue covers what else to do.

Keep someone at home in the loop. Agree on a check-in schedule, what counts as a missed check-in, and exactly what your contact should do and who they should call if one is missed. Our trip planning guide explains what a good plan contains, and Leave Word can send your itinerary to that person.

Navigation. Most thru-hikers navigate with a phone app and downloaded maps, which works well until the battery dies. Our guide to using your phone as a backcountry GPS covers setup and battery discipline; carry a power bank such as the Nitecore NB10000 Gen 3, and a paper map and compass for trails where you may leave the path. See map and compass navigation.

Hitchhiking. On many long trails, hitching is how hikers get from a road crossing to town. Laws differ between states and provinces, so know the local rules. When you do hitch, hitch with a partner when you can, keep your phone and ID on your body rather than in the pack in the trunk, text someone the plate number, and turn down any ride that feels wrong. Trail towns often have shuttle drivers and posted lists of local people who give rides, which are worth using.

Where you camp. Camp away from road crossings and trailheads, where you are more likely to meet people who are not there to hike. Trust your instincts about people; you do not owe anyone your plans, your campsite, or the fact that you are alone.

Trail culture, trail magic, and Leave No Trace at scale

Long trails have their own culture, and it is one of the best parts of the experience. Most hikers get a trail name from other hikers, usually for something they did. People starting in the same window move up the trail together in a bubble. Hostels and post offices keep hiker boxes where you leave food and gear you do not need and take what you do. Trail angels are locals and former hikers who offer rides, a place to stay, or a meal, and unexpected kindness on the trail is called trail magic.

Trail magic done badly causes real harm. The Conservancy’s trail magic guidance points out that leaving food or drinks unattended on public land is illegal, attracts bears and raccoons, and leaves trash for volunteers. Large advertised feeds bunch hikers into crowds that create new campsites in places that were untouched. If you want to give back, host in person, off the trail, in a small group (Appalachian Trail rules cap groups at 25), without publicizing it, or better still, volunteer with a trail-maintaining club. As a hiker: say thank you, never expect it, and carry out the trash.

Leave No Trace at scale. Thousands of people walking the same footpath in the same few weeks turn small habits into big impacts. Use established campsites and privies, do not create new tent sites in the bubble, dig proper catholes where there is no privy, and pack out everything. The seven Leave No Trace principles are the whole ethic in one place.

Shelter and hostel manners. Make room when someone arrives in the rain, keep quiet after dark, keep your gear in your own space, and do not use a shelter as a kitchen for a crowd if others are trying to sleep. If you are sick, stay out of shared spaces.

The mental game

Nobody walks two thousand miles on enthusiasm. There is a long middle on every long trail, after the novelty has worn off and before the end feels close, when the days blur and the question of why you are doing this gets louder. Plan for it the way you plan for a water carry.

• Write down why you are going, before you go, in your own words. On a cold wet morning in week eleven, that page is more persuasive than anything anyone else can tell you.
• Make the next town the goal, not the far terminus. Big numbers are demoralizing; the next 60 miles (100 km) are not.
• Hike your own hike. Other people’s mileage, gear and style are not a verdict on yours. Letting a group set a pace your body cannot sustain is a common way to get hurt.
• Change the plan before you quit the plan. Slow down, take a zero, flip to a different section, skip a closure, or switch to section hiking. The Conservancy recognizes section hikers exactly as it does thru-hikers once they have walked the whole trail.

After the trail. Many hikers feel flat or low for weeks after finishing. The structure, the purpose and the community that filled every day are suddenly gone. Your appetite will also outlast your mileage for a while. Plan something to look forward to, keep moving every day, stay in touch with the people you walked with, and if a low mood hangs on, talk to your doctor. It is common, and it passes.

A planning timeline

A year or more out. Choose your trail, direction and season. Talk to your employer and your family. Start saving, and start regular hiking with a loaded pack.

Six to nine months out. Watch for permit dates and apply the moment applications open. Sort passports, visas, US registration or travel insurance. Buy or upgrade the big three, then take your first overnight shakedown.

Three to six months out. Build your resupply plan and decide where you will mail boxes. Download the trail’s maps and set up your navigation app. Activate your satellite messenger. Consider a wilderness first aid course, and get a medical and dental check-up.

One month out. Do a full shakedown of three to five nights at your real starting weight. Put bills on autopay, pack your bounce box and first mail drops, and give your check-in plan and itinerary to the person at home.

The first two weeks. Short days, feet first, eat on a schedule, and let your body catch up with your enthusiasm.

Common mistakes

• Starting too fast. Fitness arrives before your tendons and bones are ready. Many early injuries are mileage errors.
• Starting with untested gear. Anything you have not used for several nights in a row is a guess.
• Packing the whole trail’s mail drops months ahead. Your appetite and your tastes will change. Mail the remote stops and buy the rest.
• Counting on caches or trail magic. Plan your water and food as if neither exists.
• Walking through sharp bone pain, or masking it with painkillers.
• Skipping water treatment because the people around you do.
• Treating closures and permit rules as optional. They are the law, and they exist because of fire, wildlife, or crowding.
• Living in town. Every extra zero costs money and makes leaving harder.
• Quitting on a bad day.

What to carry

The Ten Essentials still apply on every day of a long trail. On top of them, a thru-hike needs:

• A water system with a backup: a squeeze filter plus chemical tablets, and enough capacity for the longest dry stretch.
• A way to call for help: a satellite messenger or personal locator beacon.
• Navigation and power: a phone with offline maps, a power bank, and a map and compass where the route is remote.
• A foot kit: tape, blister dressings, a needle, and a dry pair of sleep socks.
• A small repair kit: tape, a needle and thread, and patches for your sleeping pad and shelter.
• A hygiene kit: soap, a trowel where there are no privies, and a way to pack out waste where required.
• Food storage: a bear canister where required, and bear spray in grizzly country.
• A light first-aid kit such as the Adventure Medical Ultralight/Watertight .7, topped up in towns.
• Paperwork in a waterproof bag: ID, permits, insurance details, a bank card and some cash. A small roll-top dry bag does the job.

Key takeaways

A thru-hike is won or lost on things that have little to do with fitness. Pick a trail that matches your time, experience and weak spots, and think seriously about a month-long trail or a long section first. Let the snow and the calendar choose your direction, confirm permits and border rules with the managing agency, and apply the day applications open. Budget for the income you give up and the towns you stop in, not only the gear. Get your base weight down in the big three without cutting safety, and prove your kit on a shakedown of several nights. Choose shoes on the trail rather than in a store, expect your feet to grow, and replace shoes before they wear out your knees. Resupply with a mix of town shopping and mailed boxes, and keep your town stops short. For the first two weeks walk less than you think you can, because tendons and bones adapt slower than lungs, and treat sharp bone pain as a stop sign. Eat on a schedule before hiker hunger arrives, treat every water source, wash with soap rather than sanitizer, and check for ticks every night. Respect fire closures, snowmelt fords, afternoon lightning and bear country. Carry a way to call for help and keep someone at home on a check-in plan. Treat trail magic as a gift rather than a supply plan, and leave the trail cleaner than you found it. And never decide to quit on a bad day: eat, sleep, rest, then decide.

Completion figures are the Appalachian Trail Conservancy’s reported 2025 numbers. Pacific Crest Trail figures come from the 2025 Halfway Anywhere hiker survey, a self-selected sample that likely overstates completion. Illness and injury figures are from Boulware and colleagues, “Medical risks of wilderness hiking,” The American Journal of Medicine, 2003. Calorie estimates are from Backcountry Foodie’s registered dietitian, and shoe mileage from REI’s running-shoe guidance. Trail lengths, seasons and permit rules are from the Appalachian Trail Conservancy, Pacific Crest Trail Association, US Forest Service, Continental Divide Trail Coalition, Great Divide Trail Association, Green Mountain Club, Colorado Trail Foundation, Yosemite National Park, Bruce Trail Conservancy, East Coast Trail Association and Sunshine Coast Trail, and border rules from US Customs and Border Protection and US Citizenship and Immigration Services, all current as of September 2026. These change often, so confirm with them before you go.
