About the Running Calorie Calculator
This estimates calories burned on a run from your body weight and distance. Running's energy cost is roughly proportional to weight and distance and fairly independent of pace. It's a ballpark, not an exact measurement.
How it’s calculated
Calories ≈ body weight (kg) × distance (km) × 1.03 (net energy cost of running).
Example calculation
A 70 kg runner covering 5 km burns roughly 360 calories.
Frequently asked questions
Does running faster burn more calories?
For a given distance, not much more — energy cost is mostly about distance and body weight. Running faster covers more distance in the same time, which is where extra burn comes from.
Why is this only an estimate?
Terrain, wind, fitness, and running economy all affect the real figure, and no simple formula captures them all. Use it as a rough guide.

Individual health depends on many factors this estimate does not capture. If you have questions about your health, talk to a doctor.
