Hiking burns about 275–725 calories per hour, depending on body weight, trail grade, pace, and pack weight.
Trail energy burn isn’t one-size-fits-all. Your body weight, the terrain under your boots, and what’s on your back all shift the hourly number. The good news: you can pin down a tight estimate with one simple formula and a few real-world benchmarks pulled from field-tested activity data.
Calories Burned Per Hour Hiking — Real-World Ranges
Researchers use METs (metabolic equivalents) to translate effort into energy. One MET equals 1 kcal per kilogram of body weight per hour at rest. Moderate trail walking across varied ground typically clocks near 6.0 METs, with slower ambling near 3.8 METs, and backpacking or sustained climbing rising to 7.8–10 METs. The hourly calories scale as: Calories/hour = MET × body weight (kg). A clear overview of METs lives on the CDC intensity page, and hiking-specific entries come from the Compendium of Physical Activities.
Quick Reference At A Moderate Trail Effort
The table below uses 6.0 METs (hiking across mixed terrain without a heavy load). Scan your weight to spot a solid middle-of-the-trail estimate.
| Body Weight (lb) | Body Weight (kg) | Calories/Hour (6.0 MET) |
|---|---|---|
| 120 | 54.4 | 326.6 |
| 140 | 63.5 | 381.0 |
| 160 | 72.6 | 435.4 |
| 180 | 81.6 | 489.9 |
| 200 | 90.7 | 544.3 |
| 220 | 99.8 | 598.7 |
| 240 | 108.9 | 653.2 |
Trail pace and terrain move the needle. A stroll through rolling meadows sits near the low end. A stiff climb with a daypack jumps the value by triple digits. If you plan a route with steady elevation gain, bump your estimate up a notch.
What Changes The Number
Body Weight
Heavier bodies burn more energy per hour at the same MET value, since the formula multiplies MET by kilograms. Two hikers on the same slope at the same speed can land a very different hourly count. That’s normal and expected.
Trail Grade And Surface
Uneven ground, steps, roots, and sustained uphill raise the MET. Long descents lower it a bit, though technical footing still demands work from stabilizers. A smooth gravel path with gentle rollers sits lower than a rocky ridge with punchy climbs.
Backpack Load
Carrying a daypack or overnight kit increases output. The Compendium lists backpacking and hiking with a daypack near 7.8 METs, and hill climbing with a 20-plus-pound load near 10 METs. Extra mass and steeper grades stack together, which is why summit days feel hungry.
Pace And Stops
Steady movement boosts hourly burn more than frequent long pauses. Many hikers find a rhythm: walk at a talk-friendly pace, sip water on the move, and take short breathers. That approach evens out intensity and stabilizes your per-hour tally across a long outing.
Heat, Cold, And Altitude
Hot or cold days and thinner air at elevation can nudge energy use upward. Add margin to your plan when the forecast looks spicy or the route climbs well above sea level. Comfort breaks and a modest slowdown are normal on those days.
How To Estimate Your Own Burn Rate
You can dial in a personal number in under a minute. Grab your weight, pick a MET that matches the route, and run the math.
Step 1: Convert To Kilograms
Multiply pounds by 0.4536. A 160-lb hiker equals 72.6 kg. You can round to the nearest whole number for quick field math.
Step 2: Pick A MET For The Route
- Easy meander on gentle ground: ~3.8
- Normal mixed hills and fields: ~5.3
- Cross-country hiking pace: ~6.0
- Daypack or backpack on varied terrain: ~7.8
- Steep hills with a 20+ lb load: ~10.0
These values align with the hiking entries in the Compendium of Physical Activities.
Step 3: Multiply
Use Calories/hour = MET × kg. A 72.6-kg hiker at a 6.0-MET pace lands near 436 kcal per hour. Push that to a 7.8-MET daypack pace and you’re near 566 kcal per hour. A long, steady climb with a heavy load at 10 METs rises to about 726 kcal per hour.
Step 4: Adjust For Your Style
If you tend to power up grades and take short stops, lean high. If you stroll, chat, and snap photos, lean low. Over a full day, many hikers see a mixed average that sits near their “moderate trail” number.
Worked Scenarios You Can Copy
Below is a single-weight view that shows how MET shifts play out across common trail days. The math uses 160 lb (72.6 kg) as the baseline so you can compare effort changes apples-to-apples.
| Trail Scenario (160 lb) | MET | Calories/Hour |
|---|---|---|
| Ambling, No Load | 3.8 | 275.9 |
| Normal Hillside Pace | 5.3 | 384.8 |
| Cross-Country Hiking | 6.0 | 435.6 |
| Daypack/Backpacking | 7.8 | 566.3 |
| Steep Hills + 20+ lb | 10.0 | 726.0 |
This spread matches trail lore: an easy ramble barely dents the snack bag, a pack-carry over rolling ground sits in the mid range, and long climbs with load demand steady fueling.
Fueling And Hydration Based On Your Number
Energy Timing
Eat a small snack every 45–60 minutes on days above your low-MET pace. Many hikers rotate quick carbs (fruit leather, pretzels, gels) with denser bites (nuts, bars). Steady trickle beats one giant stop, since it avoids peaks and slumps.
Meal Size
Match your hourly burn with a simple plan. If your route trends near 450–600 kcal per hour, pack 200–300 kcal snacks and alternate them. On long days, a larger mid-day wrap or rice ball helps refill glycogen and keeps legs happy.
Fluids And Sodium
Drink to thirst and bring extra in heat or on long climbs. Add a light electrolyte mix when sweat rate climbs or when your cap salt marks start to show. On cool days with mellow grades, plain water plus salty snacks often does the trick.
Pacing The Day With Your Estimate
Set A Target Average
Pick a daylong average MET that matches the route profile. A lumpy loop with a small pack might average near 6.0, even with a few short steep bursts. A load-carry to a ridge camp could average 7-plus.
Use Landmarks To Nudge Intensity
Climb steady to the saddle, snack, then jog the flat trail sections if you like a brisk cadence. Break the day into chunks—up, along, down—and let each segment set the MET.
Watch Form On Descents
Downhill work may burn fewer calories per minute than climbing, yet it taxes quads and smaller stabilizers. Shorten your stride, keep feet under your center, and save a sip for the last mile.
What The Research Sources Say
MET science started as a way to standardize activity intensity across studies. Today, coaches and everyday athletes use the same approach to plan long days out. If you want the definitions in one place, see the CDC page on intensity levels and how METs map to absolute effort. If you want activity-by-activity values, the Compendium lists hiking across several entries, including cross-country walking at 6.0 METs, slower hillside walking near 3.8–5.3, backpacking/daypack entries near 7.8, and hill climbing with a 20-plus-pound load near 10 METs. These are the anchors used in the math above.
Plan Smarter With A Few Extras
Route Notes
When scouting maps, scan total ascent, average grade, and surface. A 1,600-ft climb over four miles rides very differently than the same gain packed into two miles. A rocky tread slows the pace, raises footwork demands, and can bump your practical MET even when grade looks tame.
Pack Weight Tradeoffs
Carry the ten essentials, then trim duplication and dense packaging. Water is heavy; refill mid-route when safe. A lighter kit lowers the MET for the same pace, which can keep energy steady late in the day.
Weather Moves The Goalposts
Heat invites more fluid, sodium, and shade breaks. Cold calls for layers that vent on climbs and seal on ridges. Wind on exposed ground can chill sweat fast; stash a light shell within quick reach.
How To Use Wearables With Trail Math
Heart-rate zones pair nicely with MET-based planning. After the outing, compare your watch’s hourly burn to your table estimate. If your device reads higher on steep, loose ground, bump your chosen MET for similar routes next time. If you notice consistent overreads when you stop often, pick a slightly lower number for relaxed photo days.
Sample One-Day Plan Using Your Estimate
The Setup
Body weight: 180 lb (81.6 kg). Route: 12 miles, rolling singletrack with one 1,200-ft climb. Pack: light day kit with water and food.
The Energy Plan
- Target average: 6.0 METs on the flats, 7.0–8.0 on the climb, 4.5–5.0 on long descents.
- Estimated hourly burn: ~490 kcal on flats, ~570–650 kcal on the climb, ~370–410 kcal on descents.
- Fuel rhythm: one 220–280 kcal snack every 45–60 minutes plus a mid-day 400–500 kcal wrap.
- Fluids: 500–750 ml per hour in heat; 350–500 ml in cool shade.
This plan lands close to total energy use by dinner, keeps blood sugar level, and helps legs finish steady.
Frequently Missed Details That Skew Estimates
Long Stops
Lunch breaks drop the average. If you stop for an hour mid-day, the true per-hour number over the full outing will read lower than your moving estimate. Use separate “moving time” and “elapsed time” tallies when you analyze the day.
Underreported Pack Weight
Two extra liters of water and a warm layer add more than you think. Weigh the pack at home, then round up when you select your MET.
Altitude And Heat Combo
This pairing can slow pace and boost perceived effort. Add buffer snacks and salt, and be ready to dial back the target MET if form slips.
How To Build Your Own Table
Open a sheet, list your common body weights for you and your partners, drop in MET values for your usual trails, and multiply. After a few trips, tune the numbers to match your wearable data and how you felt at the end of each day. The goal isn’t lab-grade precision—it’s a steady plan that keeps you fueled from trailhead to tailgate.
Bottom Line For Hikers
The MET method gives you a clear, fast way to ballpark energy use on any trail. Pick a matching MET for the route, multiply by body weight in kilograms, and set snacks and fluids to match. With two or three trips of notes, your estimate will feel dialed. That means better pacing, fewer bonks, and more smiles per mile.
