How to Choose a Thru Hiking Resupply Strategy (September 2026)

I spent two summers planning my first thru hike, and the question that kept me up at night was not which pack to buy or which shoes to break in. It was food. Specifically, how I would feed myself for five straight months without a grocery store in sight. That question is exactly what a thru hiking resupply strategy solves, and choosing the right one before you step on trail is the single biggest factor in whether you finish hungry or finish strong.

A thru hiking resupply strategy is your plan for getting food, water treatment, and a few key supplies while walking 100-plus miles from one terminus to the other. Most hikers use some blend of mailed packages, town grocery runs, and shared hiker boxes. In this 2026 guide, I will walk you through the three main approaches, how they differ on the PCT, AT, and CDT, and how to pick the right mix for your body, budget, and trail.

What Is a Thru Hiking Resupply Strategy?

A thru hiking resupply strategy is the system you use to keep your food bag full between towns. On a long trail like the Pacific Crest Trail, Appalachian Trail, or Continental Divide Trail, you will typically walk three to seven days between resupply points. That means every stop has to give you enough calories and gear to reach the next one. If you plan poorly, you either end up carrying ten pounds of extra food or hiking into a ghost town with nothing open.

Most thru hikers pick from three core strategies. You can mail resupply boxes to post offices ahead of time, buy everything as you walk into towns, or combine the two. Within each strategy you also decide whether to use bounce boxes, hiker boxes, and General Delivery. The right choice depends on your food preferences, your budget, the remoteness of your trail, and how much planning time you have before your start date.

The Three Main Approaches to Resupply

Every thru hiker I know fits into one of these three buckets, even if their exact plan is a hybrid. Let me lay them out plainly so you can pick a starting point before you refine the details.

Mail Drops: Sending Food Ahead

With mail drops, you box up four to seven days of food at home and ship it to a post office or business along your trail. You arrive in town, pick up your box, repackage what fits in your bear can or food bag, and mail the empty box to your next stop. The biggest advantage is control. You decide exactly what you eat, you avoid towns with limited grocery options, and you can include specialty items for dietary restrictions. The downside is the planning time, the postage cost, and the stress of hoping your box actually arrives.

Buy As You Go: Shopping in Town

Buy as you go means you walk into town with an empty food bag and resupply at the local supermarket, gas station, or Dollar General. It is the lightest-weight option for your pack on the trail out of town, and it is the most flexible. You can react to your appetite, the weather, and what looks good after 20 miles. The downside is that some trail towns have very limited food, prices are often inflated, and you may not find the calories per ounce you want.

Combined Strategy: A Mix of Both

Most successful thru hikers use a combined strategy. They mail boxes to remote stretches where towns are scarce or have weak grocery stores, and they buy as they go everywhere else. The PCT's Sierra section, the AT's 100-Mile Wilderness, and most of New Mexico on the CDT all push hikers toward mail drops, while tourist-friendly trail towns like Bishop, California, or Damascus, Virginia, practically hand you a supermarket.

Mail Drops: Planning, Packing, and Shipping

Mail drops look intimidating the first time, but the process is repeatable. I send roughly 25 boxes for a PCT thru hike, about 12 for an AT thru hike, and I have never lost one. Here is the workflow that works.

Build a Resupply Spreadsheet

Start with a list of every resupply town on your trail, ordered by mile marker. Note the post office name, address, phone number, and the hours they hold General Delivery packages. Most post offices will hold a box for 14 days before returning it, so time your shipping carefully. If your section hike covers 20 miles a day, send a box to the stop roughly 100 miles ahead, then mail the empty box from that town to the next stop.

Pack Each Box for the Terrain

Your resupply box contents should match the section of trail. In the desert, pack extra electrolytes and ramen for hydration. In the Sierra, pack calorie-dense foods like nut butter packets and olive oil packets because the altitude kills your appetite. On the AT in spring, pack more rain-friendly food like tortillas and tuna. I keep each box to about 8 to 12 pounds of food so it still ships for under $20 in a flat rate box.

Choose Between Priority Mail and General Delivery

Priority Mail flat rate boxes are the cheapest way to ship food 1,000 miles. They arrive in three to five days and tracking is free. If you ship to a small post office in a tiny trail town, mark the box "Hold for Hiker, ETA [your arrival date]" and call the postmaster if you want extra confirmation. General Delivery means the post office holds the box for you without a PO Box, which is perfect for small towns that do not offer rentals.

Buy As You Go: Hitching, Shopping, and Timing

If mail drops feel like too much logistics, buy as you go is the easier entry point. You carry less food out of town, you adjust to your real appetite, and you support small-town grocery stores. The trick is knowing how to get to town and how to shop fast.

How to Hitch Into Town

Most thru hikers hitchhike from a trailhead parking lot into the nearest town. Stand where drivers can pull over safely, keep your pack on so you look like a hiker not a drifter, and have your thumb up. On the PCT, the California Highway 58 exit near Tehachapi is legendary for slow hitches. On the AT, Damascus and Hot Springs are easy walks into town. Plan to hitch in the morning when locals are headed to work.

How to Shop Quickly and Light

Set a calorie target before you walk into the store. Most thru hikers aim for 3,500 to 5,000 calories per day, depending on mileage and terrain. Buy high-calorie-per-ounce foods: olive oil packets, peanut butter, cheese, tortillas, Snickers, ramen, and instant potatoes. Skip heavy cans and glass. Use a small plastic bag from the dollar store to repackage everything into your food bag so you are back at the trailhead in under two hours.

When Buy As You Go Breaks Down

Buy as you go struggles in three situations: remote sections like the Sierra or the Wind River Range, towns with only a gas station, and stretches with no road access at all. If your trail includes any of those, plan at least a few mail drops for those sections specifically.

Combined Strategy: The Hybrid Approach

A combined strategy is what I recommend for first-time thru hikers. Mail drops for remote or tough stretches, buy as you go everywhere else. This gives you the reliability of mailed food where you need it, the flexibility of town shopping where you have options, and the lowest possible stress when plans change.

For a PCT thru hiker, that might look like mailing boxes for the Sierra (Kennedy Meadows South to Independence or Bishop) and for the stretch from Chester to Burney, then buying everything else in town. For an AT thru hiker, it might mean mailing a single box into the 100-Mile Wilderness and buying everywhere from Hot Springs to Damascus. The pattern is the same: mail where towns are scarce, buy where towns are abundant.

Bounce Boxes and Hiker Boxes Explained

Even after you pick a strategy, two more tools can save your hike. A bounce box is a single box of extra gear and food that you ship ahead and then forward yourself from stop to stop. A hiker box is a free pile of food and gear left behind by other hikers at hostels, campgrounds, and trail angel houses.

How Bounce Boxes Work

Pack a bounce box with items you want on hand but do not need every day: extra shoes, a new water filter, maps, special snacks, and electronics. Ship it to a town roughly 100 miles ahead, then mail it to the next resupply stop once you pick it up. You can keep it moving this way for the entire hike. The cost is roughly $15 to $25 per bounce, but the convenience is huge when you need new gear in a remote stretch.

How Hiker Boxes Work

Hiker boxes are communal piles of unwanted food, sunscreen, bug spray, and the occasional piece of gear. They live at hostels, hiker-friendly businesses, and sometimes the back of someone's car at a trailhead. The rule is take what you need, leave what you can. Treat them as bonus calories and emergency supplies, not as your main food source, because the best items disappear within hours of arriving.

Trail-Specific Strategy Differences: PCT, AT, and CDT

No single thru hiking resupply strategy works for every trail. Each of the Triple Crown has its own quirks, and the wrong plan will burn your time and money.

Pacific Crest Trail Resupply Strategy

The PCT runs 2,650 miles from Mexico to Canada through California, Oregon, and Washington. Most of the trail has easy road access every 100 to 150 miles, with strong grocery options in towns like Big Bear, Bishop, Bend, and Stehekin. Buy as you go covers about 70 percent of the trail. You will likely need mail drops for the Sierra, the section between Chester and Burney in Northern California, and any stretch where you are skipping a town. Most hikers send 10 to 25 boxes for the entire hike.

Appalachian Trail Resupply Strategy

The AT runs 2,200 miles from Georgia to Maine, and resupply is rarely more than 50 miles apart. Towns are dense, gas stations and Dollar Generals are common, and road walks connect most gaps. Most AT thru hikers buy as you go for the whole hike, with mail drops only for the 100-Mile Wilderness in Maine and a few stretches through the Smokies. Sending 5 to 12 boxes is typical, and many hikers send zero.

Continental Divide Trail Resupply Strategy

The CDT is the most remote of the three, with stretches in New Mexico, Wyoming, and Montana where resupply is 150 to 200 miles apart. Buy as you go is risky here. Most CDT hikers send 20 to 35 boxes and rely heavily on bounce boxes for spare gear. If you plan to hike the CDT, start packing boxes three months in advance, and budget extra for postage to tiny post offices in places like Pie Town, Anaconda, and East Glacier.

Calorie and Nutrition Planning Basics

Whatever strategy you pick, you need a calorie target. Most thru hikers need between 3,500 and 5,000 calories a day, with high-mileage days in the mountains pushing toward 6,000. The exact number depends on your body weight, your metabolism, and how much climbing you are doing. Do not save money by cutting calories. Skimping on food is the number one reason hikers quit early.

Aim for 100 to 130 calories per ounce of food. Olive oil packets, nut butter, cheese, and chocolate are your highest-density options. Balance them with carbs like instant rice, ramen, and tortillas for quick energy. Add one salty snack per day to keep cramps away, and pack a few multivitamins for the second half of a long hike when your fresh food variety drops.

Common Resupply Mistakes to Avoid

I have made most of these mistakes, and I have watched friends make the rest. Avoid them and your hike will be smoother.

Overpacking Food Out of Town

When you walk into a town hungry, you buy too much food and end up carrying it for two extra days. Eat a big meal first, then shop for what you actually need. If you arrive hungry, buy extra on the next stop and recalibrate.

Underestimating Calorie Needs

Most first-time thru hikers plan for 3,000 calories a day and burn 4,500. After three weeks you will start losing weight and feeling tired. Plan for more than you think you need, and pack extra olive oil and nut butter for calorie boosts without weight.

Ignoring Plastic Bag Bans

Eight US states ban single-use plastic bags, and several trail towns have stopped providing them. Pack a few lightweight stuff sacks or ziplocks from home so you can repackage food in states like California, New York, and Vermont.

Waiting Too Long to Mail Boxes

If you are mailing boxes ahead, send them no later than three weeks before you expect to arrive. Post offices only hold General Delivery packages for 14 days. A late box that gets returned to sender can leave you without food for a 100-mile section.

Forgetting Dietary Restrictions

Vegetarian, vegan, and gluten-free hikers will struggle to find protein options in small AT towns. If you have restrictions, plan for more mail drops and call ahead to hostels to ask what they can stock for you.

Resupply Planning Checklist: What to Prepare Before You Step on Trail

Once you have chosen your strategy, run through this checklist so nothing slips on day one. I use it for every long-distance hike I plan.

Build Your Resupply Map

Plot every town along your trail on a spreadsheet. Note mile markers, post office addresses, business hours, and the distance between stops. Aim for a maximum of 130 miles between resupplies so a missed box does not leave you stranded. Tools like FarOut and Guthook make this easy to visualize on your phone.

Calculate Calorie and Cost Targets

Decide on a daily calorie target before you start packing boxes. Multiply that by the number of days between resupply stops to get your per-box food weight. For a 5-day stretch at 4,000 calories, that is 20,000 calories per box, or roughly 8 to 10 pounds of food. Budget $1 to $1.50 per 1,000 calories for mail drop contents, or $1.50 to $2.50 per 1,000 calories for town purchases.

Plan Mail Drop Timing

Send each box three weeks before you expect to arrive at that town. Track shipment numbers so you can call the post office if a box is late. Label every box clearly with your name, phone number, and the words "Hold for Hiker, ETA [date]" so the postmaster does not return it early.

Prepare for Dietary Restrictions

If you are vegan, vegetarian, gluten-free, or allergic to nuts, expect to send more mail drops than the average hiker. Pack protein-dense options like beef jerky substitutes, single-serve hummus, and protein powder. Call hostels and outfitters along your route to ask what they can hold for you.

Adapt Your Strategy Mid-Hike

Your resupply plan will fail somewhere, and that is normal. A box will be late, a town will be closed, or your appetite will change. Replan from town. Drop the boxes you no longer need, send new ones from the post office, and adjust your calorie targets based on how your body actually feels after week three.

Frequently Asked Questions

Final Verdict

If you are planning your first thru hike and want the lowest-stress option, start with a combined strategy. Mail a handful of boxes to remote or tough sections and shop in town everywhere else. It keeps your pack light, your food reliable, and your budget manageable.

For experienced hikers who want total control, go with mostly mail drops. Plan every stop, send 20-plus boxes, and include a bounce box for spare gear. For budget hikers who do not mind hitchhiking and improvising, buy as you go works on the AT and most of the PCT, and it lets you adapt to your real appetite. Whichever route you take, lock in your plan at least a month before your start date, rehearse one box shipment as a trial, and let me know how it goes from the trail.
