Hiking for one hour typically burns 300–700 calories, depending on body weight, trail grade, pace, and pack load.
You came here for a clear number. Here it is: most adults will see a per-hour burn that lands somewhere between the mid-300s and the high-600s. That swing isn’t guesswork. It comes from the activity’s MET value (a standard way to express intensity), your body weight, and how steep or loaded the trek gets. Use the quick tables and steps below to pin your own range without guessy online calculators.
Calories Burned In One Hour Of Hiking: Realistic Ranges
Calorie burn during a steady trail hour scales with intensity. Easy rolling paths sit near the low end. Steep climbs and backpacking bump the number up fast. The math uses this simple rule of thumb: calories per minute ≈ MET × 3.5 × body weight (kg) ÷ 200. Multiply by 60 for an hour. MET rises with effort, so a hillier or faster hour yields a larger result.
Common MET Values For Trail Pace And Load
Different sources list close ranges. A widely cited compendium places day-hike style walking around 6 MET, steeper work and poles higher, and backpacking near 7–8 MET. The exact figure shifts with terrain and load, which is why your own range beats a single average.
Broad Early-Look Table (Pick Your Row)
The table below shows hourly burn for two intensities—moderate trail (≈6 MET) and backpacking or steep terrain (≈7.8 MET)—across common body weights. Numbers are rounded to keep the grid readable.
| Body Weight | Calories/Hour (≈6 MET) | Calories/Hour (≈7.8 MET) |
|---|---|---|
| 120 lb (54 kg) | 343 | 446 |
| 150 lb (68 kg) | 429 | 557 |
| 180 lb (82 kg) | 514 | 669 |
| 210 lb (95 kg) | 600 | 780 |
If you sit between listed weights, read between the rows. If your route is mixed—some climb, some flats—your real-world hour will sit between the two intensity columns.
How To Calculate Your Own Number In Under A Minute
Grab your weight and a reasonable intensity pick. Use this three-step process and you’ll have a tight estimate that beats generic charts.
Step 1: Convert Weight To Kilograms
Take your weight in pounds and divide by 2.2046. A 170-lb hiker is ~77 kg. If you track in kilograms already, you’re set.
Step 2: Choose A MET That Fits Your Route
Use 5.3–6 for a steady, rolling trail with pauses, around 7 for steeper hills, and ~7.8 for backpacking or sustained climbs. Trekking poles, altitude, heat, or loose footing nudge the number upward. Smooth dirt paths or cool weather bring it down a notch.
Step 3: Run The Hourly Math
Calories per hour ≈ MET × 3.5 × body weight (kg) ÷ 200 × 60.
Example: 170 lb (77 kg) on a hilly route at 7 MET → 7 × 3.5 × 77 ÷ 200 × 60 ≈ 565 kcal per hour.
What Moves The Number Up Or Down
Two hikers on the same trail can see very different burns. These levers explain why your smartwatch or chest strap often shows a range over the day.
Grade And Elevation Gain
Climbing drives intensity. Even a mild grade changes leg mechanics and breathing. Long stair-step climbs or switchbacks shift an easy outing into a higher MET bracket.
Load And Gear
Carrying water, a camera, or an overnight kit adds work. A light day pack hardly moves the needle. A loaded pack pushes the hour closer to backpacking territory.
Surface And Conditions
Loose rock, sand, snow, mud, or roots increase demand. Hot or humid weather raises heart rate at the same pace. Cold air can do the same if you’re overdressed and breathing through layers.
Pace, Breaks, And Group Dynamics
Short stops lower the true hourly average. A steady moderate pace keeps the number consistent. Group hikes often surge and stall; you may see a wider spread across hours.
Body Size And Efficiency
Heavier bodies burn more per minute at the same MET. Over weeks, practice trims the cost a touch at a given pace, though steeper work still spikes the burn.
Trusted Benchmarks You Can Cross-Check
The activity compendium used by coaches and researchers defines METs and lists values for hiking, backpacking, and walking variants. You can cross-check the intensity ranges there. A well-known medical school reference also prints 30-minute burn estimates for several body weights, including cross-country hiking. Linking both sources lets you sanity-check the tables above and the quick formula.

Practical Ways To Tailor The Estimate To Your Trail
Numbers get better when they match your route and style. Use these simple tweaks to refine your hour-by-hour picture.
Match MET To The Steepest Segment
Your overall hour often reflects the hardest section more than the flats. If the loop has a long climb and a rolling return, pick the higher MET for the ascent hour and the lower MET for the rest. That yields a realistic day total.
Account For Pack Weight
Day pack with water, snacks, and a layer? Treat it like a small bump within the 6–7 MET band. Multi-day load with shelter and food? Push toward the 7.5–8 range.
Use A Range, Not A Point
Give yourself a top and bottom number. Terrain, weather, and group pace change minute by minute. Planning with a band keeps your fueling and water plan flexible.
Sync With Your Wearable—But Don’t Let It Be The Only Judge
Wrist-based readings can drift during uneven climbs or in cold air. Chest straps track heart rate spikes better. If your device shows consistent under-reads on climbs, nudge your planned burn up by 5–10% for those hours.
Worked Examples You Can Borrow
Example A: Rolling Trails, Light Day Pack
Body weight 150 lb (68 kg). Pick 6 MET. Hourly burn: 6 × 3.5 × 68 ÷ 200 × 60 ≈ 429 kcal. Two hours on this terrain land near 850–900 kcal.
Example B: Steep Ascent With Poles
Body weight 180 lb (82 kg). Pick 7 MET. Hourly burn: 7 × 3.5 × 82 ÷ 200 × 60 ≈ 617 kcal. Expect a lower hour on the descent—closer to the mid-500s if footing is loose.
Example C: Overnight Load
Body weight 210 lb (95 kg). Pack and climbs push intensity near 7.8 MET. Hourly burn: 7.8 × 3.5 × 95 ÷ 200 × 60 ≈ 780 kcal. A milder camp approach might sit closer to the mid-600s.
Expected Hourly Burn Across Common Scenarios
This second table helps you connect the dots between terrain and a realistic hourly number for a typical 150-lb hiker. Swap in your own weight by scaling up or down.
| Scenario | Approx. MET | 150-lb Calories/Hour |
|---|---|---|
| Rolling Trail, Few Stops | 6.0 | 429 |
| Hilly Route, Steady Climb | 7.0 | 517 |
| Backpacking Load Or Long Grades | 7.8 | 557 |
| Loose Surface Or Heat | 7.0–7.8 | 517–557 |
| Cold Day, Smooth Path | 5.3–6.0 | 379–429 |
Fueling And Pacing Tips That Fit Your Numbers
Once you have your hourly burn, you can plan snacks and water without hauling extra weight. Here’s a simple way to put the math to work on your next outing.
Use The “Half Back” Snack Rule
If the hour sits near 450 kcal, carry snacks that return ~200–250 kcal per hour on the move. That keeps energy steady without gut strain. Save the rest for longer stops or the drive home.
Front-Load Water On Climbs
Climbs raise breathing rate and sweat loss. Take small sips every 10–15 minutes during ascent hours. Back off a touch on shaded descents. Electrolytes help on hot days or routes over two hours.
Keep A Steady Cadence
Even splits—climb at a sustainable tempo, walk the flats, jog short downhills—keep your hourly burn predictable. High-low surges feel exciting at the start but drain the tank early.
How This Guide Was Built
Numbers here come from the widely used MET approach and published activity tables for hiking and backpacking. MET stands for metabolic equivalent; 1 MET equals resting energy, and values scale with intensity. The compendium lists activities and MET values, including hiking variants. Harvard’s table reports 30-minute burn numbers by weight class. Converting those to an hour tracks closely with the math shown above. Linking both lets you check the logic and apply it to your route with confidence.
Quick Reference: One-Glance Takeaways
- A steady trail hour sits near 400–600 kcal for many adults; backpacking or long grades push higher.
- Use calories per minute ≈ MET × 3.5 × kg ÷ 200; multiply by 60 for the hour.
- Pick a MET that reflects your toughest segment. Climb hours burn more than rolling hours.
- Carry snacks that replace roughly half of what you spend while moving; drink by thirst with steady sips on climbs.
Plan Your Next Trek With Honest Numbers
You don’t need a lab to size your burn. A simple MET pick, your weight, and the hour formula give you a tight, trail-ready range. Use the first table to scan where you’ll likely land, the second table to match terrain, and the steps above to customize the number for your loop or out-and-back. That way your food, water, and pace line up with how the day actually feels underfoot.
