Running Calorie Burn by Pace Calculator
Estimate the calories you burn running from your pace, body weight and duration — faster pace covers more ground and burns more.
How it works
Speed = 60 ÷ pace(min/km) · Distance = duration ÷ 60 × speed · Calories ≈ weight × distance × 1.036 kcal/kg/km
The energy cost of running is remarkably close to a fixed amount per kilometre per kilogram of body weight — about 1.0 kcal (net) or 1.036 kcal (gross) per kg per km — largely independent of how fast you run. So for a fixed time, a faster pace burns more mainly because you cover more distance. This tool converts your pace to a speed, works out the distance for your duration, and applies the per-kilometre energy cost scaled by your weight.
Worked example
A 70 kg runner at 6 min/km runs at 60 ÷ 6 = 10 km/h. In 30 minutes that is 0.5 h × 10 = 5 km. Calories ≈ 70 × 5 × 1.036 ≈ 363 kcal.
Frequently asked questions
Does running faster burn more calories?
For the same distance, pace has only a small effect — running a kilometre costs roughly the same energy whether you jog or sprint it. For the same amount of time, a faster pace burns more because you cover more distance. Sprinting also raises after-burn (EPOC) somewhat.
Why about 1 kcal per kg per km?
It is a well-established approximation of the metabolic cost of running on level ground. Heavier runners burn more (the weight term), and hills, wind, soft ground and running economy shift it up or down.
Is this net or gross calories?
This uses the gross figure (~1.036 kcal/kg/km), which includes the energy you would have burned at rest anyway. Net calories — the extra above resting — are a little lower, around 0.9–1.0 kcal/kg/km.
