Running Calorie Calculator
Estimate calories burned running based on distance and body weight.
The Running Calorie Calculator estimates the calories you burn during a run based on distance and body weight. The formula uses the factor of 1.036 kcal per kg per km, which accounts for the average energy cost of running.
Enter your running distance in kilometers and your weight in kg. Heavier runners burn more calories per kilometer because they expend more energy moving their mass. The calculation is independent of speed because running burns roughly the same calories per km regardless of pace.
This is a net calorie estimate (total burned minus what you would burn at rest). Running is one of the most efficient calorie-burning exercises available.
Frequently Asked Questions
Does running speed affect calories burned?
Per kilometer, the difference is minimal. Running 5K at any speed burns roughly the same calories. However, faster running burns more calories per minute.
How accurate is this estimate?
Within about 10-15% for most people. Uphill running, wind resistance, and running efficiency can affect actual calorie burn.
How many calories does a 5K burn?
For a 70kg person: approximately 362 calories. For an 80kg person: approximately 414 calories.
