Running Calorie Calculator
Estimate calories burned while running from body weight and distance. Optional duration adds pace context.
Duration is optional. If entered, the calculator also shows estimated pace.
Privacy: runs locally in your browser. No values are stored or transmitted.
How it works
This calculator uses a simple rule-of-thumb estimate for running energy cost: about 1 kcal per kg per km.
Optional duration is used to estimate pace, but the calorie estimate itself is mainly based on weight and distance.
Examples
- 70 kg running 5 km → about 350 kcal estimate
- 154 lb running 3.1 miles → imperial inputs are converted internally
- Add duration to estimate average pace

FAQ
- What does this calculator estimate?
It estimates calories burned while running based on body weight and distance covered.
- Does pace matter?
Yes, but this simplified model mainly estimates energy cost from body weight and distance. Duration is used for pace context.
- Is this exact?
No. Actual calorie burn varies with pace, terrain, weather, efficiency, and body composition.
- Can I use miles instead of kilometers?
Yes. The calculator supports both metric and imperial inputs.
- Are my running details stored?
No. All calculations run locally in your browser.
