Hiking calories per hour: about 420–480 at 150 lb, rising to 500–700 on steep trails or with a pack.
If you want a straight answer for a one-hour hike, here it is: your burn hinges on body weight, trail grade, pace, and backpack load. A lighter hiker on a smooth path lands near the low end; heavier hikers, hills, and packs push the number up fast. The ranges below come from standard MET values used by exercise scientists and field guides.
Calories Burned In 60 Minutes By Weight And Terrain
The table uses established energy costs for hiking: a “moderate trail” aligns with a MET of ~6.0, and “steep or with a daypack” aligns with ~7.8 from the Adult Compendium of Physical Activities. Use it as a quick read on where your session likely lands.
| Body Weight | Moderate Trail (~6.0 MET) |
Steep Or With Daypack (~7.8 MET) |
|---|---|---|
| 120 lb (54 kg) | 330–360 kcal | 430–470 kcal |
| 150 lb (68 kg) | 420–480 kcal | 550–620 kcal |
| 180 lb (82 kg) | 500–570 kcal | 660–740 kcal |
| 210 lb (95 kg) | 580–660 kcal | 770–860 kcal |
| 240 lb (109 kg) | 660–740 kcal | 880–970 kcal |
What Drives Calorie Burn On A Hike
Body Weight
Energy cost scales with mass. Two people on the same trail at the same pace will not match; the heavier hiker spends more energy each minute.
Trail Grade And Surface
Climbing hills bumps energy demand sharply. Loose rock, roots, or sand raise the effort even when pace stays the same.
Pace
Speed changes the picture. A brisk hour on rolling terrain often lands in “vigorous” territory by MET rules, while a leisurely wander stays moderate.
Backpack Load
Carrying a daypack raises the workload. Heavier loads and stair-like climbs compound the effect.
Heat, Altitude, And Stops
Hot days, thin air, and lots of pauses nudge the numbers. Heat and altitude raise strain; frequent photo breaks lower the total.
How The Math Works (Plain And Fast)
MET is a standard unit for energy cost. One MET equals sitting quietly. Activities are assigned MET values; calories burned per minute follow this simple rule:
kcal per minute = MET × 3.5 × body weight (kg) ÷ 200
Run that for 60 minutes to get an hourly number. Hiking on varied terrain usually ranges from ~5.3 MET (normal pace across fields and hillsides) up to ~8.0+ when climbing or backpacking. You can read the official definitions on the CDC guide on intensity and METs and check activity-specific values in the Adult Compendium tables (PDF). Both open in a new tab.
Calories Burned From One Hour Of Hiking — Real-World Ranges
Here are realistic one-hour ranges you can trust. These align with field charts that list hiking energy cost for different body weights.
Flat Or Rolling Trail, Light Daypack
At ~6.0 MET, a 150-lb hiker spends around 420–480 kcal in 60 minutes. Lighter bodies land closer to 330–360; heavier bodies climb to 580–660.
Steep Sections Or Heavier Pack
At ~7.8 MET, a 150-lb hiker typically sits near 550–620 kcal per hour. Add extra grade or a loaded pack and the hour can reach 700+ kcal at higher body weights.
Backpacking Pace On Mountain Trails
With sustained climbing and a pack, published MET values reach 8.0 and beyond. That puts many hikers between 600 and 900 kcal per hour, depending on weight and how continuous the climb is.
Worked Example You Can Copy
Say you weigh 180 lb (82 kg) and plan a steady hour on a rolling state-park loop at roughly ~6.0 MET.
- Convert weight to kg: 180 ÷ 2.205 ≈ 81.6 kg.
- Apply the rule: 6.0 × 3.5 × 81.6 ÷ 200 = 8.568 kcal per minute.
- Multiply by 60 minutes: 8.568 × 60 ≈ 514 kcal for the hour.
If your loop includes long climbs (closer to ~7.8 MET), the same steps yield about 670 kcal for the hour.
How Pace And Elevation Change The Hour
Small changes turn into big totals across 60 minutes. Use this table as a quick check for a 150-lb hiker; adjust up or down if your body weight differs.
| Pace / Elevation | MET | Calories / Hour (150 lb) |
|---|---|---|
| Normal Pace Through Fields And Hills | ~5.3 | ~375–420 |
| Cross-Country Hiking, Rolling | ~6.0 | ~420–480 |
| Sustained Uphill, No Pack | ~6.3 | ~440–490 |
| Climbing With A Daypack | ~7.3–7.8 | ~520–620 |
| Backpacking With Steady Climb | ~8.0+ | ~600–700+ |
Ways To Raise Or Lower The Burn Safely
Add Elevation, Not Just Speed
Hills raise energy demand fast and keep impact manageable compared with all-out running.
Use Load Sparingly
A small daypack adds a nice bump. Make gradual jumps; big loads spike joint stress and fatigue.
Pick Terrain Intentionally
Rock gardens, stairs, and sand require more work. Choose routes that match your legs and your plan for the day.
Drink, Eat, And Pace
Bring water and a snack for efforts beyond an easy loop. If your route includes long climbs, plan your timing and heat exposure and keep the pace steady.
Three One-Hour Plans With Estimated Burn
City Preserve Loop (40 Minutes Rolling + 20 Minutes Stairs)
Assume ~6.0 MET for the rolling segments and ~6.3–7.0 on stairs. A 150-lb hiker lands near 460–520 kcal. Swap stairs for a final ridge push and the hour edges higher.
State Park Ridge And Return (30 Minutes Climb + 30 Minutes Descent)
Uphill sits near ~6.3–7.8 MET depending on grade and footing; downhill costs less. A 180-lb hiker often lands near 520–650 kcal across the hour.
Pine Forest Pack Walk (Light Daypack, Rolling)
With ~7.3 MET on steeper bits and ~6.0 elsewhere, a 210-lb hiker generally sees 700–820 kcal in an hour if the route keeps moving.
Why Trackers And Apps Disagree
Devices lean on pace, grade, heart rate, and sometimes pack load. Small errors in any input change the result. If your watch lags on steep switchbacks or your phone under-reads grade, the calorie readout drifts. Cross-check with MET math when numbers look off.
How To Self-Calibrate Your Numbers
Log A Baseline Hour
Pick a familiar trail and steady pace. Note distance, gain, temperature, and any pack weight. Compare your device to the MET-based estimate that matches the route.
Repeat And Adjust
Run the same loop later under similar weather. If your watch always reads low on climbs, add a small manual bump for hilly days.
Use Weight-Based Scaling
When hiking with friends, scale the estimate by body weight in kg. It’s a fast way to personalize the same route.
Mistakes That Skew The Estimate
- Using flat-ground numbers on a mountain trail. Uphill changes the math.
- Ignoring backpack load. Even a light daypack nudges energy cost.
- Counting only moving time. Snack breaks still consume some energy, but the per-minute rate falls.
- Assuming downhill “doesn’t count.” Eccentric work still burns calories and taxes legs.
- Copying someone else’s readout. Weight and pace matter; copy-paste estimates rarely match.
Quick Recap
For a one-hour hike, most people land between 400 and 900 kcal depending on weight, grade, pace, and pack. You can get a tight estimate with one line of math using a MET that matches your route. Use hills and small loads to raise the burn, and lean on official tables when planning your day.
