Ask a long-distance walker what they remember from a trek and the food will come up before the summits. Meals are morale, and on a multi-day route your body is burning through fuel at a rate your normal appetite barely recognises — several thousand calories on a hard day, day after day. The walkers who finish strong are rarely the fittest; they are the ones who ate enough, ate often, and actually enjoyed what was in their food bag. Food planning is not admin. It is strategy.
How much food you actually need
A useful planning figure for mountain walking is around 3,000 calories a day and up on big days — more than most people eat at home, and your hunger will lag a day or two behind your expenditure, so eat on schedule even before you feel ravenous. The trap is the three-meals model: on the trail you need to graze. Keep snacks in hip-belt pockets and eat something every hour or so — a handful of nuts, a piece of chocolate, some dried fruit. Steady intake beats a heroic dinner.
Weight discipline matters because food is the other heavy thing in your pack. Experienced backpackers plan on roughly 2 lb (about 1 kg) of food per person per day, and the way to hit that number while staying fuelled is calorie density: aim for foods delivering on the order of 400+ calories per 100 grams. Olive oil, nuts, nut butters, cheese, chocolate and dried meats are the workhorses; fresh fruit and vegetables are lovely but mostly water weight, so they earn their place on day one, not day five.
Building the daily menu
Write it down. A simple chart — breakfast, lunch, dinner, snacks for each day — stops you overpacking ‘just in case’ food that you will carry for a week and bring home uneaten. Then build each day from a small repertoire of proven meals rather than improvising in a supermarket the night before.
Breakfasts want to be fast and hot: instant oatmeal with powdered milk, cinnamon and dried berries; or muesli with nuts. Add instant coffee or a spoonful of nut butter and you have a 500-calorie start in ten minutes. Lunches are usually eaten on the move, so they should need no cooking: tortillas (light, durable, nearly indestructible) with hard cheese, salami or tuna packets; or the classic hiker’s handfuls of trail mix. Dinners are the reward: instant rice or noodles with olive oil, dried vegetables, spices and cheese; or a freeze-dried meal on nights when you cannot face cooking. Pack one small luxury per day — good chocolate, a favourite tea, hot cocoa — because on day six it will matter more than any gear upgrade.
Test everything at home first. Cook the actual meals on your actual stove, eat the actual portions, and adjust. Discovering that you hate your dinner menu is a problem best solved in your kitchen, not at 3,500 metres.
Resupply strategy
On routes that pass through towns — most long trails in Europe, the Appalachian Trail, the Te Araroa — the standard rhythm is a resupply every three to five days, buying as you go rather than mailing boxes of food to yourself. Buying as you go keeps you flexible: your appetite, your pace and the weather will all change, and a fixed parcel schedule can turn into a forced march to meet a post office.
Where the trail is remote, plan the carry in segments: know exactly which stretch has no shops and pack that stretch’s food as a sealed unit. And wherever you are, keep one emergency meal — something dense and comforting — permanently in the bottom of the food bag, untouched until you genuinely need it. It is the cheapest insurance in your pack.
Food storage and animals
Your food plan is also a wildlife plan. In bear country, that means the local system — bear canisters, hangs, or provided lockers — used properly every single night, with everything scented (food, toiletries, rubbish) stored together away from the tent. Elsewhere the antagonists are smaller but persistent: mice, marmots and monkeys have all ended trips. Hang or hard-case your food, never eat in the tent, and pack every scrap of rubbish out. A chewed-through food bag on day two is a liability, not an anecdote.
Practical tips
Repackage everything before you leave: ditch the cardboard boxes and bulky packaging, decant into zip bags, and label them by day or meal so you are not excavating the whole food bag at every stop. Keep the day’s snacks where your hands can reach them without removing the pack. And remember the social dimension — on hut-to-hut routes and teahouse treks, meals are bought at the lodges and the economics flip entirely (you carry almost no food, but the budget needs a different line). Match the food system to the route, write the chart, and eat like it matters. It does.
