Start with the trail, not the snacks
Distance, time, and elevation drive how much you eat. A flat two-mile walk needs far less food than a steep eight-mile climb. Enter the trail first, then adjust snacks to match.

How to use this worksheet
Pick a realistic interval
Most hikers do well with a small snack every 45 to 60 minutes. If the trail is hot, steep, or above 6,000 feet, shorten the interval. If you are walking slowly on flat ground, you can stretch it.
Mix quick fuel and steady fuel
Quick fuel is fruit, candy, or a gel. It works fast but fades fast. Steady fuel is nuts, bars, cheese, or jerky. It lasts longer. A good plan has at least one of each.
Common mistakes
- Carrying only candy or only bars. Your stomach will get tired of one texture.
- Eating the biggest snack at the start. Spread calories across the hike.
- Forgetting salt. If you sweat a lot, add salty snacks or electrolytes.
- Packing for the best weather. Add an extra portion per person if rain or wind is likely.
Example: half-day hike, two people
Six miles, moderate hills, mild weather. Interval: 50 minutes. Snacks: trail mix, apple, peanut butter bar, salted peanuts. Plan: four stops, two portions per person per stop, about 1,100 calories each. Add one emergency bar per person.
Before you go
Double-check the weather, trail conditions, and group experience. If anyone is new to hiking, add an extra snack and plan one more short stop. It is easier to carry a little extra than to run out.
Questions hikers ask
- How do I know if I packed enough?
- Compare your plan to past hikes. If you usually feel hungry at the two-hour mark, add a stop earlier. If you often carry food home, reduce portions by 10 percent next time.
- What if someone in the group has allergies?
- Build the snack list around the most restrictive diet first. Use separate bags for each person if needed. Label them before the hike.
- Can I use this for trail running?
- Yes, but shorten the interval to 20 or 30 minutes and favor quick fuel. Reduce portion size so your stomach can handle it while moving fast.
- Does this replace a real meal?
- No. This is for snacks between meals. Eat a real breakfast before long hikes and a real dinner after. On very long days, plan one full lunch stop in addition to snacks.
