Running Calories Burned Calculator

This calculator estimates how many calories you burn while running using the MET method (metabolic equivalent of task). From your body weight, distance and time it works out your average speed, picks the matching MET value and computes total calories burned plus calories per kilometre. Enter your body weight, the distance covered and your running time. The calculator shows total calories burned, average speed, the MET value applied and the energy cost of one kilometre.

How we calculate calories burned

Speed (km/h) = distance / (time in minutes / 60). The MET value is chosen by speed: below 8 km/h is 8.3; 8–9.6 is 9.8; 9.7–11.2 is 11.0; 11.3–12.8 is 11.8; 12.9–14.4 is 12.8; from 14.5 is 14.5. Calories = MET x body weight x (time / 60), since 1 MET = 1 kcal/kg/h. Calories per kilometre = calories / distance.

Example: 70 kg, 5 km in 30 minutes

Speed = 5 km / 0.5 h = 10 km/h, which gives MET 11.0. Calories = 11.0 x 70 kg x 0.5 h = 385 kcal. Calories per kilometre = 385 / 5 = 77 kcal/km.

Frequently asked questions

How many calories does running burn?

It depends on body weight, pace and time. A 70 kg person running 5 km in 30 minutes burns about 385 kcal. The heavier you are and the faster you run, the more calories you burn.

What is a MET?

MET stands for metabolic equivalent of task, a measure of exercise intensity. 1 MET equals burning about 1 kcal per kilogram of body weight per hour. Running ranges from roughly 8.3 to 14.5 METs.

How are calories calculated from METs?

Calories = MET x body weight (kg) x time (hours). For MET 11, weight 70 kg and 0.5 hours that is 11 x 70 x 0.5 = 385 kcal.

Yes, a faster pace means a higher MET and more calories per minute. Over a fixed distance the difference can be smaller, because a faster run takes less time.

Roughly 1 kcal per kilogram of body weight per kilometre. A 70 kg person burns about 70 kcal per kilometre, though the exact value depends on pace.

No, the MET model assumes running on flat ground. Running uphill or on difficult surfaces burns more calories than the calculator shows.

Yes, calorie burn is directly proportional to body weight. A 90 kg person burns about 30% more than a 70 kg person on an identical run.

Sports watches use heart rate and personal data for more precise estimates. The MET method is a simple averaged model that gives an indicative value.

Yes, as a guide. To lose weight your overall energy balance must be negative. The result estimates energy expenditure that you can compare with your diet.

The result is an estimate based on MET values. Actual burn depends on fitness, terrain and heart rate. Treat the figure as indicative and consult a coach or dietitian if needed.
