Calories Burned Running Calculator
Calculate calories burned running or jogging based on distance, speed, weight, and terrain.
Find the metabolic equivalent (MET) and compare to walking.
How Running Calories Are Calculated
The standard method for calculating exercise calorie burn uses MET — Metabolic Equivalent of Task. MET represents the ratio of your metabolic rate during exercise to your resting metabolic rate. An activity with MET = 8 burns 8 times as many calories as sitting still.
Formula: Calories = MET × Weight (kg) × Duration (hours)
This means heavier people burn more calories doing the same activity — because it takes more energy to move a larger body mass.
MET Values by Running Pace
| Speed | MET (approximate) |
|---|---|
| 4 mph (6.4 km/h) — slow jog | 6.0 |
| 5 mph (8.0 km/h) — easy run | 8.3 |
| 6 mph (9.7 km/h) — moderate | 10.0 |
| 7 mph (11.3 km/h) — fast | 11.5 |
| 8 mph (12.9 km/h) — very fast | 13.5 |
| 9 mph (14.5 km/h) — racing pace | 15.0 |
| 10 mph (16.1 km/h) — elite | 16.0 |
MET values come from the Compendium of Physical Activities (Ainsworth et al., updated 2011).
Terrain Multipliers
Running on flat road or a track is the baseline. Other surfaces increase calorie burn:
- Treadmill (flat): Slightly easier than outdoor running due to no wind resistance — use same MET
- Treadmill 5% incline: Adds approximately 20-30% to calorie burn
- Trail/uneven terrain: +5% vs flat road (proprioception, stabilization demand)
- Moderate hills: +10–15% vs flat road
- Running in heat or cold also increases energy expenditure (not captured here)
Running vs Walking
A common misconception: running and walking the same distance burn similar calories. In reality, running burns approximately 1.5–2× more calories per mile than walking, because the mechanics are fundamentally different — running involves a ballistic flight phase where the body must be propelled upward, requiring far more force production.
The Afterburn Effect (EPOC)
Running — especially at higher intensities — creates Excess Post-Exercise Oxygen Consumption (EPOC). Your metabolism remains elevated for 15 minutes to several hours after intense running. For easy runs, EPOC adds roughly 5–10 extra calories. For hard intervals, EPOC can add 50–100+ calories. This calculator shows the exercise calories only, not EPOC.
Using Calories for Weight Management
One pound of body fat stores approximately 3,500 calories. Running 5 miles at 6 mph (for a 70 kg person) burns approximately 560 calories — equivalent to losing about 0.16 lbs of fat from that single run. Consistent training combined with appropriate nutrition is the key to long-term weight management through running.
