Hiking burns roughly 300–600 calories per hour for a 150–200 lb hiker, with speed, grade, pack weight, and terrain shifting the total.
You came here to get a clear number and a simple way to estimate your own burn on the trail. You’ll get both. The short story: body weight, grade, pace, and pack load drive the math. Below you’ll find a quick formula, ready-to-use tables, and a few dials you can turn to raise or lower the estimate with confidence.
Calories Burned Hiking: Quick Formula That Works
Scientists use MET values (metabolic equivalents) to estimate energy use. One MET equals resting effort. Hiking ranges from about 3.8 to 9.0+ METs depending on terrain and load. The calorie formula is simple:
Calories per hour ≈ MET × 3.5 × body weight (kg) ÷ 200 × 60.
That condenses to MET × 1.05 × body weight (kg). Pick a MET that matches your trail, then multiply. MET references for hiking come from the Compendium of Physical Activities, a standard used by researchers and coaches.
Fast Reference Table: Trail Type Vs. Calories Per Hour
The numbers below use common hiking METs and two sample body weights. Values are rounded to keep this fast to use.
| Trail Type | 150 lb (68 kg) | 200 lb (91 kg) |
|---|---|---|
| Easy Trail (3.8 METs) | 271 kcal/hr | 363 kcal/hr |
| Moderate Trail (5.3 METs) | 378 kcal/hr | 506 kcal/hr |
| Cross-Country (6.0 METs) | 428 kcal/hr | 573 kcal/hr |
| Uphill Steady (7.3 METs) | 521 kcal/hr | 698 kcal/hr |
| Uphill Hard (9.0 METs) | 643 kcal/hr | 860 kcal/hr |
Where do those METs come from? The adult Compendium of Physical Activities lists hiking cross-country near 6.0 METs and climbing hills from about 6.3 up to 9.0+ as grade and pack weight rise. That’s why steep, loaded climbs feel like a workout even at slower speeds.
Pick Your MET: Match The Trail You’re On
Flat Or Rolling Singletrack
Use 3.8–5.3 METs. Think gentle trails, light roots and rocks, and little elevation gain. This covers social hikes, photo stops, and family walks where pace dips and surges.
Mixed Terrain With Regular Climbing
Use 6.0–7.3 METs. You’re moving at a steady clip, stepping over rocks and roots, and gaining elevation. Heart rate runs higher, and breaks feel welcome at viewpoints.
Steep Grades Or Heavy Pack
Use 9.0 METs or more. This is the zone for long climbs, scree, snow, or a backpacking kit. Even short bursts up a steep pitch can push the average here.
Turn Dials To Customize Your Estimate
Body Weight
More mass means more energy to move. Two hikers on the same trail can differ by hundreds of calories across a long day. Use your own weight in kilograms for the best fit.
Pace
Speed doesn’t change the MET directly, but faster movement usually pairs with harder terrain or fewer breaks. If you’re cruising beyond 3 mph on dirt, lean toward the higher MET in the range.
Elevation Gain
Grade drives effort. Short steep ramps spike energy use even if the average pace looks modest. If your route stacks long grades back to back, select a higher MET.
Pack Weight
Every extra pound costs a little. Researchers bump the MET to reflect loads. A day pack barely moves the needle. A backpacking rig can push your selection from the 6–7 range toward 9–10.
From Per Hour To Per Mile
Per-mile numbers help with trip planning. To get calories per mile, divide hourly burn by your speed. Many hikers average about 2.5 mph on rolling trails. Use that as a baseline and adjust for your pace.
Trail Calories Per Mile (2.5 Mph Baseline)
| Trail Type | 150 lb (68 kg) | 200 lb (91 kg) |
|---|---|---|
| Cross-Country (6.0 METs) | 171 kcal/mile | 229 kcal/mile |
| Uphill Steady (7.3 METs) | 208 kcal/mile | 279 kcal/mile |
| Uphill Hard (9.0 METs) | 257 kcal/mile | 344 kcal/mile |
Hike slower and the per-mile number rises; hike faster on the same terrain and it falls. Speed changes time under load, which changes energy use per mile.
Worked Examples You Can Copy
One-Hour Out-And-Back On Rolling Hills
Hiker weight 180 lb (82 kg). Trail feels steady but not brutal, so pick 6.0 METs. Calories per hour ≈ 6.0 × 1.05 × 82 = 517. Expect about 500–520 kcal for the hour.
Backpacking Climb With A Weekend Kit
Hiker weight 150 lb (68 kg) with a 25 lb pack on a long grade. Use 9.0 METs. Calories per hour ≈ 9.0 × 1.05 × 68 = 643. A two-hour climb lands near 1,280–1,300 kcal before the descent.
How A Slower Pace Shifts Per-Mile Burn
Take the 6.0 MET scenario above at 2.0 mph. Hourly burn for a 200 lb (91 kg) hiker is ≈ 573 kcal. Divide by 2.0 to get 286 kcal per mile. Bump speed to 3.0 mph on the same grade and it drops to 191 kcal per mile.
How This Lines Up With Published Charts
Harvard’s long-running calorie tables place hiking in the same range you see here. Their chart shows values for 125, 155, and 185 lb body weights across many activities, including hiking and stair climbing. The Compendium provides the MET backbone that feeds those tables. When you anchor your estimate to those sources, your math stays grounded.
Set A Sturdy Plan For Long Days
Estimate Total Trip Burn
Multiply hourly burn by moving time. Many outings mix flat, rolling, and steep sections. Use a weighted average MET for a tighter estimate. A loop with half rolling (6.0) and half sustained climbs (7.3) works out to about 6.65 METs. Run the math once, then bring a little buffer.
Fuel And Hydration
Match intake to effort. Long climbs pair well with bite-size carbs you can eat while moving. Mix in salty snacks on warm days and steady sips of water. Cold days often need more calories for warmth during breaks.
Pacing And Breaks
Short, regular breaks keep legs fresh. Two minutes every 20–30 minutes lets you reset without getting chilled. A steady rhythm saves energy over a day of surges and stops.
Ways To Raise Or Lower The Burn
Want More Burn?
- Pick a route with more sustained climbing.
- Add poles and keep arms engaged on hills.
- Carry water from the last reliable source to add a small load.
- Hike a touch faster on flats while staying in control on descents.
Want Less Burn?
- Choose gentler grades and shaded routes.
- Lighten the pack: drop duplicate items and heavy extras.
- Use a smoother pace with fewer sprints after photo stops.
- Take longer breaks before big climbs.
How To Track On The Trail
Watches and fitness apps estimate energy use with heart rate, pace, and elevation gain. Accuracy varies. The best check is still your own math. Keep the MET range in mind and compare it with what your device shows at the end of the day. Over a few hikes you’ll spot a pattern and dial the estimate in.
Method Notes And Limits
METs Are Averages
Numbers come from groups of people under test conditions. Real trails add heat, cold, wind, mud, snow, sand, and stop-and-go movement. Expect swing.
The Talk Test Helps Pick Intensity
If you can talk in full sentences you’re likely in the moderate range. If you can only get out a few words between breaths, you’re in the vigorous range. Hiking on steep grades usually lands in that second bucket; see CDC intensity guidance for the definitions tied to METs.
Treadmill Vs. Trail
Gym calculators use speed and grade on a belt with no roots or rocks. Trail hiking costs more because stability muscles work hard and the surface slows you down.
Common Trail Days And Rough Totals
Here are three quick sketches that mirror popular outings. They’re not lab results; they give you a ballpark that lines up with the tables and formula above.
Half-Day Ridge Walk
Moving time 3 hours at 6.0 METs with a few snack breaks. A 170 lb (77 kg) hiker lands near 6.0 × 1.05 × 77 = 485 kcal per hour. Multiply by 3 and you’re around 1,450 kcal for the moving portion. Add a small buffer for cold wind on the ridge and photo pauses that stretch the clock.
Steep Summit Push
Two hours up, one hour down on loose rock with a light day pack. Uphill work averages 9.0 METs; the descent eases toward 6.0. A 200 lb (91 kg) hiker sees ≈ 9.0 × 1.05 × 91 × 2 hours = 1,911 kcal for the climb and ≈ 573 kcal for the descent. Trip total lands near 2,500 kcal.
Desert Stroll At Sunset
Flat, sandy singletrack at a social pace around 3.8 METs for 90 minutes. A 150 lb (68 kg) hiker looks at ≈ 271 kcal per hour, so about 400 kcal for the outing. Soft sand may bump that a little.
Small Technique Tweaks That Save Energy
Shorten Steps On Steep Grades
Short, quick steps keep hips level and reduce side-to-side sway. You’ll keep traction and limit wasted motion.
Use Poles Like A Metronome
Plant with the opposite foot and keep a steady rhythm. Poles shift a slice of the work to your upper body and help brake on descents.
Stand Tall Over The Pack
Stack hips under ribs, keep eyes up, and let your arms swing. Slouching folds the torso and makes breathing feel harder than it needs to be.
Warm Up Early
Five easy minutes at the trailhead primes ankles and hips. Start smooth and your effort curve looks better all day.
Bottom Line For Trip Planning
Pick a MET from the range that matches the day. Multiply by 1.05 and your weight in kilograms to get calories per hour. Scale by time for the full day and divide by pace for per-mile needs. Bring food and water for that number plus a small cushion. That’s trail math you can trust.
