Calorie calculator Running Calorie Calculator

Estimate the energy expenditure (calories) during a running session by considering your weight, distance, speed, elevation gain/loss, as well as environmental conditions (wind, temperature).

2. Calculation details

The calculator uses the metabolic energy cost of running (about 1 kcal/kg/km on flat ground), then adjusts it based on several factors:

  • Speed: running faster increases cost per kilometer slightly.
  • Elevation gain: each meter of climb adds extra cost (about +2 kcal/kg/100m).
  • Descent: cheaper than flat, but some eccentric braking (about −0.5 kcal/kg/100m).
  • Wind: a headwind of 10-15 km/h can add 3 to 5% to the cost.
  • Temperature: running in very hot (>30°C) or very cold (<5°C) conditions increases energy expenditure slightly (thermoregulation).
  • Terrain: technical terrain (trail, mud) increases metabolic cost by 5 to 15%.

These values are theoretical estimates. Individual expenditure varies depending on running economy, experience, morphology. This calculator should not replace medical or nutritional advice.

3. Comparison with other activities

To give you an idea, here are approximate expenditures for a 70 kg person for 1 hour of activity:

Activity Approximate consumption (kcal/h)
Walking (5 km/h) ~250-300 kcal
Jogging (8-10 km/h) ~550-650 kcal
Running (12 km/h) ~750-850 kcal
Running (15 km/h) ~950-1050 kcal
Cycling (moderate effort) ~400-500 kcal
Swimming (continuous) ~500-600 kcal

4. Limitations and tips

  • The formula gives an indicative order of magnitude, not a precise medical value.
  • Running economy (efficiency) varies: two runners can have up to 20-30% difference in cost for the same pace.
  • Training effect: experienced runners are more economical at a given pace.
  • Don't forget basal metabolism (calories burned at rest during the day): add 1.2 to 1.4 kcal/min for an average adult (~70-85 kcal/h).
