A 10-mile hike typically burns ~900–1,600 calories for most adults; body weight, pace, grade, and pack weight shift the total.
Here’s a clear, data-based way to answer the big question for a 10-mile day. Calorie burn depends on time on trail and the intensity of the effort. Intensity is often described with MET values (metabolic equivalents). “Hiking, cross-country” is listed at ~6.0 MET in the Adult Compendium of Physical Activities, and backpacking ranges higher. Using the standard MET equation, you can pin down a personal number without guesswork.
Calories Burned On A 10-Mile Hike: Fast Estimate
Start with a level trail, no heavy pack, and a steady pace. The table shows totals for three body weights across three common paces using the 6.0 MET value for cross-country hiking. Time rises as speed drops, so calories rise at slower paces.
| Body Weight | Time For 10 Miles | Calories (Level Trail, ~6.0 MET) |
|---|---|---|
| 55 kg (121 lb) | 5:00 at 2.0 mph | ~1,732 |
| 55 kg (121 lb) | 4:00 at 2.5 mph | ~1,386 |
| 55 kg (121 lb) | 3:20 at 3.0 mph | ~1,155 |
| 70 kg (154 lb) | 5:00 at 2.0 mph | ~2,205 |
| 70 kg (154 lb) | 4:00 at 2.5 mph | ~1,764 |
| 70 kg (154 lb) | 3:20 at 3.0 mph | ~1,470 |
| 90 kg (198 lb) | 5:00 at 2.0 mph | ~2,835 |
| 90 kg (198 lb) | 4:00 at 2.5 mph | ~2,268 |
| 90 kg (198 lb) | 3:20 at 3.0 mph | ~1,890 |
Where do these numbers come from? The Compendium assigns ~6.0 MET to cross-country hiking. Calories per minute = MET × 3.5 × body weight (kg) ÷ 200. Multiply that rate by the minutes for your 10 miles at your pace.
What Changes The Total For Ten Miles
Pack Weight And Grade
Carrying a pack or climbing hills drives the intensity up. The Compendium lists backpacking and hill grades with higher METs than relaxed trail walking. More METs means more energy per minute, even before you account for slower uphill speed. Field models from Army research also show steep grades and carrying loads add a sizable bump to energy use.
Body Weight
All else equal, a higher body mass pushes the per-minute number up. That shows in the table: the same 10 miles at the same pace costs more for a 90 kg hiker than for a 55 kg hiker.
Pace And Time On Feet
A slow pace stretches the clock. Since the rate is calories per minute, extra minutes stack up. On easy ground, a ~3 mph cruise keeps time down; on rocky or steep terrain, expect 2–2.5 mph and a bigger total.
Authoritative Numbers You Can Trust
Two references underpin the estimates:
- Adult Compendium (2024) hiking METs – “Hiking, cross-country” ~6.0 MET; backpacking and hill grades trend higher.
- LCDA walking equation – a validated model for graded walking and load carriage that aligns with measured energy cost.
How To Estimate Your Own 10-Mile Total
Step 1: Pick A MET That Matches Your Plan
Use ~6.0 for a cross-country trail with light gear. Pick ~7.0–7.8 for a daypack/overnight load. For steady hill climbing with a noticeable pack, use the higher hill-and-load entries. The Compendium sheet lists codes for each case.
Step 2: Convert Body Weight To Kilograms
Pounds ÷ 2.2046 = kilograms. A 165 lb hiker is ~75 kg.
Step 3: Estimate Time For Ten Miles
Use your typical park pace. Many hikers sit near 2–3 mph, with 2 mph on rugged climbs and closer to 3 mph on smooth, rolling trail.
Step 4: Run The Equation
Calories per minute = MET × 3.5 × kg ÷ 200. Multiply by your minutes on trail. Example: 75 kg at 3 mph on easy ground (6.0 MET). Ten miles at 3 mph takes ~200 minutes. Rate = 6.0 × 3.5 × 75 ÷ 200 = 7.875 kcal/min. Total ≈ 7.875 × 200 = 1,575 kcal.
Real-World Scenarios For Ten Miles
Easy Loop With A Small Daypack
Think rolling trail, few roots, pack under 10 lb. A 70 kg hiker at ~3 mph with 7.0 MET (daypack) lands near 1,700 kcal. If pace slips to 2.5 mph, time grows and the total lands closer to 2,100 kcal.
Steady Climb With Moderate Load
Climbing for long stretches slows speed and increases intensity. Using the Compendium’s hill-and-load entries, the MET can reach the high-7s or 8s. A 70 kg hiker at 2 mph with an 8.3 MET hill-and-load entry could see ~2,430 kcal for the day.
Fast Cruise On Smooth Trail
When footing is clean and grade is mellow, 3 mph is realistic. With a light vest and a MET near 6.0, totals stay toward the low end of the range.
Pack Weight And Hill Grade: Practical Multipliers
The Compendium offers METs across conditions. You can turn those into quick multipliers against a 6.0 MET baseline. Multiply the baseline calories by the ratio (MET ÷ 6.0) to get a rough adjusted total for the same time on trail.
| Condition | MET | Calories Vs 6.0 MET |
|---|---|---|
| Fields And Hills, No Load | ~5.3 | × 0.88 |
| Cross-Country Trail | ~6.0 | × 1.00 |
| Backpacking / Daypack | ~7.0–7.8 | × 1.17–1.30 |
| Climbing Hills + 10–20 lb | ~7.3 | × 1.22 |
| Climbing Hills + 21–42 lb | ~8.3 | × 1.38 |
| Climbing Hills + 42+ lb | ~9.0 | × 1.50 |
Examples Using The Multipliers
Daypack Upgrade
Take the 70 kg, 3 mph, 6.0 MET baseline: ~1,470–1,575 kcal for ten miles depending on the time you used. Swap to ~7.0 MET for a daypack: total × 1.17. So ~1,720–1,840 kcal.
Hill Climb With A Heavier Load
Use the 8.3 MET row (21–42 lb, hill grade). Multiply your baseline by 1.38. A 90 kg hiker who would sit near ~1,890 kcal at 3 mph on level ground now sits near ~2,610 kcal for the same time; slower speed would add more minutes and a larger total.
Why METs Are The Standard Here
METs come from measured oxygen uptake. One MET equals the energy cost of quiet sitting. Activities are coded as multiples of that rate. The Compendium compiles these values for many tasks, including trail travel, daypacks, and hill grades. The Army-validated walking model backs up the grade and load effects shown in field tests. This combo gives you a sound basis for planning snacks and fluids for a long day out.
How Terrain And Footing Nudge The Math
Rocks, roots, sand, snow, water crossings—each slows you down and bumps up the minutes on feet. Even if MET stays the same, more minutes add calories. Many hikers average 2–2.5 mph on rough ground, then slide past 3 mph on a smooth forest road. For a fixed distance like ten miles, speed is the hidden lever.
Pack Smarter For Energy And Comfort
Trim Non-Essentials
Every pound counts across ten miles. Stash only what you’ll use. Repackage food, right-size your water based on refill points, and swap bulky items for lighter equivalents when possible.
Wearable Data With A Grain Of Salt
Watches can drift. They often estimate calories from heart rate and simple speed models. Cross-check a hike or two with the MET method. If your watch reads low or high by a set percentage, note the offset and plan your snacks accordingly.
Snack Planning For A Ten-Mile Outing
Energy intake is personal, yet some starting points work well. Many hikers aim to replace a portion of the burn during the day and finish the deficit with meals. Here’s a simple approach:
- Pack 200–300 kcal per hour of moving time.
- Split carbs across bars, fruit, and simple trail mixes; add salt on hot days.
- Carry a small “bonus” snack (~250 kcal) for unexpected delays.
Frequently Missed Details That Skew Estimates
Grade Direction
Downhill isn’t free. Gentle descents save energy; steep downhills require braking, which costs energy and can slow pace due to caution.
Stop Time
Food photos and viewpoint breaks don’t add much, but a long lunch doesn’t burn hiking calories. Keep the stopwatch honest by tracking moving time.
Weather
Heat, cold, wind, and rain all change comfort and speed. Soft ground after a storm can knock a half mile per hour off your pace.
Do A Quick Back-Of-The-Map Check
Grab your expected pace and the table that matches your weight. If your route includes a steady climb and a loaded pack, apply the multipliers. The range you get—usually near 900–1,600 kcal for many hikers on easier trails, and higher for slower, hillier days—offers a solid guide for food and fluids.
Method Snapshot
Equation: calories per minute = MET × 3.5 × kg ÷ 200. METs and examples come from the Adult Compendium list for hiking and load carriage; grade and load effects align with the LCDA model used in field work. These sources give consistent results across paces and terrain types.
