Most hikers burn about 240–710 calories in a one-hour hike, depending on body weight, pace, grade, and any pack.
If you want a quick estimate for a one-hour hike, start with your body weight and the trail profile. Gentle paths land near the low end. Steep climbs or a loaded pack push you to the top of the range. The math behind these estimates comes from METs (metabolic equivalents), a standard way to turn movement into energy use. You’ll see the simple steps below with real numbers backed by lab-tested values.
Calorie Burn From A One-Hour Hike: What To Expect
Calorie burn rises with three main levers: body weight, grade, and pace. A heavier hiker burns more at the same speed. A steeper trail raises effort. A pack amplifies the load on every step. On mellow terrain, many hikers fall between 300 and 500 calories per hour. Add steady climbing and the same person can hit 575–900+ per hour.
At-A-Glance Numbers By Weight And Terrain
These hourly totals use established MET values for “normal trail” (≈5.3 MET) and “steep uphill” (≈8.0 MET). See the method notes below for sources and the exact equation.
| Body Weight | Normal Trail (5.3 MET) | Steep Uphill (8.0 MET) |
|---|---|---|
| 120 lb (54 kg) | ~303 kcal/hr | ~457 kcal/hr |
| 150 lb (68 kg) | ~379 kcal/hr | ~572 kcal/hr |
| 180 lb (82 kg) | ~454 kcal/hr | ~686 kcal/hr |
| 210 lb (95 kg) | ~530 kcal/hr | ~800 kcal/hr |
| 240 lb (109 kg) | ~606 kcal/hr | ~914 kcal/hr |
“Normal trail” here means mixed-surface walking through fields or rolling hills at a conversational pace. “Steep uphill” means a sustained climb in the 6–15% grade band. Numbers are rounded to keep the table scan-friendly.
How The Math Works (Simple And Reliable)
Researchers assign each activity a MET value. One MET is resting energy cost. Hiking sits above everyday walking and climbs fast with grade and load. The CDC’s MET overview explains the unit in plain terms, and the peer-reviewed Compendium lists the values used by exercise scientists. The latest adult list shows entries such as “Hiking, cross country” at 6.0 MET and specific uphill or loaded scenarios across the 6.5–10.0+ range. You can review the reference list here: Adult Compendium (2024) walking & hiking codes.
The Equation You Can Use
Calories per minute = MET × 3.5 × body weight (kg) ÷ 200. Multiply by 60 for one hour. This is a standard in exercise science and matches how universities teach MET math. A clear primer: Texas A&M MET guide.
Worked Example: 150-Pound Hiker On A Gentle Trail
150 lb = 68.0 kg. Using 5.3 MET (gentle mixed terrain):
- Per minute: 5.3 × 3.5 × 68 ÷ 200 ≈ 6.3 kcal
- Per hour: 6.3 × 60 ≈ 379 kcal
Worked Example: 180-Pound Hiker On A Steep Climb
180 lb = 81.6 kg. Using 8.0 MET (sustained uphill):
- Per minute: 8.0 × 3.5 × 81.6 ÷ 200 ≈ 11.4 kcal
- Per hour: 11.4 × 60 ≈ 686 kcal
Pace, Grade, And Pack: What Moves The Needle
Pace And Terrain
Flat dirt roads and smooth singletrack sit near the low end of the range. Rocky paths, steps, loose sand, or tundra add cost even at the same speed. The Compendium lists values from ~5.3 MET on varied hillsides at a normal pace to ~8.0 MET for walking 2.9–3.5 mph on a 6–15% grade.
Grade
Every rise in grade means more vertical work. A small bump (1–5%) already increases the rate. By the time you’re on a steady 10% climb, the per-hour total can be hundreds more than a flat stroll at the same speed.
Pack Weight
Carrying 10–20 lb on hills bumps effort into the mid-6s (MET). Heavier loads (20–40 lb) push toward the mid-7s. Long climbs with 20+ lb can reach ~10 MET depending on grade and pace. Those values come straight from the Compendium’s walking and pack-carry codes in the adult reference list linked above.
Altitude, Heat, And Footing
Thin air, heat, and technical footing make the same pace cost more. The equation here doesn’t add a separate altitude or temperature factor, yet your heart rate and breathing will. Expect your personal number to land on the higher side in those settings.
Quick Estimator You Can Run In Your Head
Want a fast field method? Convert pounds to kilograms by dividing by 2.2. Pick a MET that matches the trail: ~5.3 for easy rolling, ~6.0 for cross-country pace, ~8.0 for a steady climb, 6.5–10.0+ if you’re climbing with a pack. Then do this: MET × kg × 1.05 = calories per hour. That “1.05” is the 3.5 ÷ 200 × 60 part bundled together.
Two Quick Scenarios
- 135 lb day hiker on rolling trail: 61.2 kg × 5.3 × 1.05 ≈ ~340 kcal/hr.
- 200 lb hiker on steady 10% climb: 90.7 kg × 8.0 × 1.05 ≈ ~764 kcal/hr.
How A Pack Changes One Hour Of Hiking
Loads shift the math. The second table shows a realistic impact for a 180-lb hiker. Use it as a guidepost when you add water, camera gear, or a kid carrier.
| Load / Grade Scenario | Approx MET | Estimated kcal/hr (180 lb) |
|---|---|---|
| Climbing, +10–20 lb pack, 5–10% grade | 6.5 | ~557 |
| Climbing, +21–40 lb pack, moderate–brisk | 7.5 | ~643 |
| Climbing, 20+ lb pack, 5–20% grade | 10.0 | ~857 |
These match the adult reference list entries for hill climbing with specified loads. If your pack is lighter and the trail is rolling, slide down toward the 5.3–6.0 zone.
Sample One-Hour Outings With Estimates
Gentle Loop Near Town
Think of a park trail with small ups and downs and firm footing. A 150-lb hiker usually lands near 350–400 calories in an hour. A 200-lb hiker often lands near 475–525. Poles don’t change the math much here, but they can smooth your rhythm and reduce stumbles, which helps you hold pace.
Steady Climb To A Viewpoint
Picture a 1,200-foot gain in 3 miles. That’s an average 7–8% grade. A 150-lb hiker sits near 550–600 calories in an hour on the steeper segments. A 200-lb hiker can sit around 725–775. Throw in heat or altitude and your heart rate will spike sooner, nudging your burn upward.
Pack-Carry Conditioning Hike
Add 25–30 lb and aim for brisk uphill walking. The Compendium’s codes for loaded hill walking point to the mid-7s to ~10 MET depending on grade. For a 180-lb hiker, that’s roughly 640–860 calories per hour. Ease the grade or drop the load and the number comes down fast.
Ways To Nudge The Number (Up Or Down)
Raise It
- Seek vertical: Choose routes with sustained climbing.
- Add resistance: Pack water or a sandbag for training days.
- Pick a brisk cadence: Shorter, quicker steps on climbs keep momentum.
Dial It Back
- Smooth your line: Favor firm surfaces and packed switchbacks.
- Share the load: Split group gear and water carry.
- Cool times of day: Early starts reduce heat stress.
Fueling And Pacing For A Better Hour
Eat a light snack 30–60 minutes before you start, then sip fluids during the hour. On steeper routes, break the climb into steady intervals. Pick a pace you can hold while talking in short phrases; that lands you near moderate to vigorous effort without blowing up. If you wear a heart-rate monitor, you’ll see the spikes on steep pitches or with a heavy pack.
Method Notes And Sources
All numbers come from the MET method used by exercise scientists. One MET represents the resting oxygen cost (≈3.5 ml/kg/min). To get calories per hour, use MET × 3.5 × body weight (kg) ÷ 200 × 60. This is the same math used in university references and certification texts. For the activity values, see “Hiking, cross country” (6.0 MET), varied hillsides at a normal pace (≈5.3 MET), walking 2.9–3.5 mph uphill at 6–15% grade (≈8.0 MET), and hill-climbing entries that add pack weight in the adult reference list.

What This Means For Your Next Hour On Trail
Pick your route and your pace, note your weight, then plug the numbers into the quick equation. On easy ground, many hikers land near 300–500 calories in an hour. Add grade or a pack and your tally rises fast. Track a few outings with the same loop and you’ll get a personal baseline you can trust for training, fueling, or weight-management goals.
