Calories Burned Running Calculator

How many calories does running burn?

Calorie burn during running scales primarily with body weight and running speed. A 70 kg person running at a moderate 10 km/h for 30 minutes burns approximately 360 kcal; a heavier person or faster pace increases this proportionally. Running at 14 km/h burns roughly 25% more per kilometre than running at 10 km/h because the MET value rises from 9.8 to 12.3.

This calculator uses the standard metabolic formula: Calories = (MET × 3.5 × weight in kg) ÷ 200 × duration in minutes. MET (metabolic equivalent of task) values represent energy expenditure as a multiple of resting metabolic rate.

Running intensity and MET values

A light jog under 8 km/h has a MET of approximately 7.0. An easy run at 8 km/h is MET 8.0. Moderate running at 10 km/h is MET 9.8, the most commonly cited running value. Tempo running at 12 km/h raises this to MET 11.0, and fast running at 14+ km/h reaches MET 12–14.5.

These figures are from Ainsworth et al. (2011), the standard reference for physical activity METs. Individual calorie burn varies based on running efficiency, terrain, and fitness level.

Calories per km vs calories per hour

Running burns roughly 60–80 kcal per kilometre for a person weighing 70 kg, depending on pace. This remains relatively stable across speeds because faster running covers more distance per minute. Per-hour calorie burn, however, increases significantly with pace — jumping from about 490 kcal/hr at an easy 8 km/h jog to over 950 kcal/hr at race pace.
