Resupply simply means restocking your food and supplies along the trail, and every thru-hiker does it dozens of times, so getting the system right early saves weight, money, and stress for the whole hike. The basic rhythm is to hike from one town or road crossing to the next, eat down your food bag as you go, and restock when you reach a store, a post office, or a hostel that accepts packages. Most sections between resupplies last three to seven days, which means you rarely need to carry more than a week of food at a time.

The simplest resupply strategy, and the best starting point for beginners, is to buy food in towns as you go. Grocery stores, convenience stores, and even petrol stations along the trail stock the staples hikers live on: oats, tortillas, peanut butter, noodles, bars, and dried fruit. Buying as you go lets you adjust to your changing appetite, avoids the cost and hassle of shipping boxes, and means you never carry food you have gone off. The downside is that small stores have limited choice and higher prices, especially for special diets.

Mail drops, boxes you ship ahead to a post office, hostel, or store, are useful in specific situations rather than as a default strategy. Send a box when the next town has no real grocery store, when you need special dietary food, medication, or gear replacements, or when you want to include a treat that is hard to find on trail. Label boxes clearly with your name and expected arrival date, check holding times and opening hours before you ship, and never send a box to a place you have not confirmed will hold it.

Planning each section starts with three numbers: the distance to the next resupply, your expected daily mileage, and the days of food that distance requires, plus one extra day as a buffer. A section of 100 miles at 20 miles a day needs five days of food, plus a buffer day, so six days in total, and at roughly two pounds of food per day that is about twelve pounds to start the section. As your fitness and mileage grow, sections get shorter in days even if the distance stays the same, which is why early sections feel heaviest.

Food fatigue is a real problem on long hikes, because eating the same meals for weeks makes it hard to eat enough. Rotate your dinners, change your snacks every few resupplies, and include at least one food you genuinely look forward to each day, even if it is not the most efficient choice. Town meals matter too: a proper meal in town, with fresh food and plenty of calories, helps you recover and resets your appetite for the next section, so do not rush straight through town without eating well.

Money and logistics deserve as much planning as food. Budget for higher grocery prices in small trail towns, for postage on any boxes you send, and for occasional hostel stays, laundry, and gear replacement. Keep a simple list of your next few resupply points with distances and notes on what each town offers, and update it as you hear news from other hikers, because stores close, post offices change hours, and trail conditions shift. Flexibility beats a rigid plan every time.

Finally, remember that resupply gets easier with practice, and most beginners over-plan their first boxes and under-plan their flexibility. Start with buying in towns, send boxes only where they clearly help, carry a buffer day of food, and learn from each section: what you ate, what you carried home, and what you wished you had. Within a few weeks, resupply becomes routine, and the trail rhythm of hiking, eating down the food bag, and restocking in town becomes one of the most satisfying parts of a thru-hike.
