Estimate calories burned on a trail run from your weight and distance, with advanced options for elevation gain, terrain, and calories per mile.
Trail Running Calories Burned Formula
Distance estimate uses an unvalidated distance shortcut with a fixed assumed coefficient:
Calories Burned (kcal) = Weight (lb) × Distance (miles) × 0.80
Terrain and elevation estimate adds optional uphill gain (blank means zero) and an assumed trail factor:
Calories Burned (kcal) = [Weight × Distance × 0.80 × Trail Factor] + [Weight × Elevation Gain (ft) × 0.0013]
Variables:
- Weight is your body weight in pounds.
- Distance is your trail run distance in miles.
- Trail Factor is an assumed surface adjustment, not a measured or validated category: 1.00 for a typical dirt trail, 0.95 for a smooth packed trail, 1.10 for a technical trail, and 1.20 for a steep rocky trail.
- Elevation Gain is the total climb during the run in feet.
What is Trail Running?
Trail running is running on natural surfaces such as dirt, gravel, forest, desert, and mountain trails. Compared with road running, it usually includes more climbing, more uneven footing, and more frequent pace changes.
Calories Burned Trail Running by Distance
For a 150-lb runner using the distance shortcut (unvalidated planning estimates):
| Distance | Calories Burned |
|---|---|
| 1 mile | 120 calories |
| 3 miles | 360 calories |
| 5 miles | 600 calories |
| 8 miles | 960 calories |
| 10 miles | 1,200 calories |
How to Calculate Calories Burned Trail Running
- Enter your body weight and select pounds or kilograms.
- Enter your trail distance and select miles or kilometers.
- For the optional adjustments, choose Terrain and elevation estimate, select the assumed terrain factor, and optionally enter total uphill gain.
- Select Calculate for the shortcut estimate. Actual energy varies; gross versus active energy is unspecified and this is not a fueling prescription.
Example
Weight = 150 pounds
Distance = 5 miles
Calories Burned = 150 × 5 × 0.80 = 600 calories
