How Many Calories Do You Burn Running
Running is one of the most effective physical activities for calorie expenditure. Knowing the calories burned helps you plan training based on your goals.
The Formula
Calorie burn is calculated using MET values from the Compendium of Physical Activities:
Calories = MET x weight (kg) x duration (hours)
MET values for running vary with speed:
- 8 km/h (light jog): MET 8.5
- 10 km/h (easy run): MET 9.3
- 12 km/h (medium run): MET 11.8
- 14 km/h (fast run): MET 12.5
- 16 km/h (intense run): MET 14.8
Practical Example
A 75 kg person running 8 km at 11 km/h:
- Duration: 8 / 11 = 0.73 hours (about 44 minutes)
- MET: 10.5
- Calories: 10.5 x 75 x 0.73 = 575 kcal
- Calories per km: 575 / 8 = 72 kcal/km
Running for Weight Management
ACSM recommends 150-300 minutes of moderate activity or 75-150 minutes of vigorous activity per week for weight management. Running, being a high-energy vigorous activity, allows you to achieve significant goals in relatively short times.
