Calories Burned Running Calculator
Estimate calories burned running from your weight, distance, and pace.
Estimated Calories Burned
This is an estimate of net energy burned. Your pace has only a minor effect on the total at a given distance.

How Running Calorie Burn Works
Running burns roughly 1 kilocalorie per kilogram of body weight per kilometer travelled. This calculator uses the widely cited estimate of net calories ≈ weight (kg) × distance (km) × 1.036. Because the energy cost of moving your body over a fixed distance is fairly constant, distance and body weight are the two biggest drivers of total calories burned.
Factors That Affect It
- Terrain & incline - hills and soft surfaces increase the energy cost.
- Pace - faster running burns slightly more per kilometer, but the effect is small.
- Fitness level - more efficient runners use somewhat less energy.
- Wind, temperature, and running form - all cause minor variation.
Accuracy Caveats
This is a net-energy estimate, meaning it approximates the calories burned above resting metabolism. Real-world values vary by 10-20% depending on the factors above. For precise measurement you would need lab-based metabolic testing. Use this figure as a practical guide rather than an exact number.
