Estimate the calories you burn while running from your body weight and either the distance you covered or the time and pace you held. Running has a fairly steady energy cost per kilometre, so weight and distance do most of the work.
Estimate running calories from distance, or from time and pace.
kcal = weight (kg) × distance (km) × 1.036 pace mode: distance = time (min) ÷ pace (min per km)
The factor 1.036 is a common estimate of the net energy cost of running per kilogram per kilometre. It assumes steady running, not walking, and it scales linearly with distance.
| Symbol | Meaning |
|---|---|
| weight | Your body mass in kilograms. |
| distance | How far you ran, in kilometres. |
| time | How long you ran, in minutes (pace mode). |
| pace | Minutes per kilometre (pace mode). |
A 70 kg runner covering 5 km burns about 70 × 5 × 1.036 = 363 kcal. At a pace of 6 minutes per kilometre, that same 5 km takes 30 minutes.
Running energy cost depends mainly on how far you go and how much you weigh, because each stride lifts and decelerates your body mass against gravity. A widely used approximation is about 1.036 kilocalories per kilogram of body weight per kilometre travelled, a figure that stays remarkably stable across a range of comfortable speeds.
That means a seventy kilogram runner covers roughly 72.5 kilocalories per kilometre, so a ten kilometre run lands near 725 kilocalories gross. The value is a gross estimate, including the calories you would have burned resting during the same time.
At moderate paces, the extra energy of moving faster is largely offset by the shorter time spent running, so cost per kilometre changes little. The real drivers are distance, body mass, and terrain. Uphill running adds a climbing cost that the flat per kilometre figure ignores, and soft or sandy surfaces increase it further.
The calculator also offers the MET route, where running MET values rise with pace, and that method captures the effect of a harder effort within the same distance. Use the per kilometre method when you know your route, and the MET method when you know your pace and duration.

Running burns roughly twice as much per kilometre because of the higher intensity, even though it covers the same ground faster.
