Running Calories – Distance & Speed Calculator

Running burns calories in proportion to body weight, distance covered and speed — and the MET system captures all three. Each pace maps to a metabolic equivalent: an 8 km/h jog is 8.3 METs, a 10 km/h run 9.8 METs, a 12.5 km/h tempo run 11.8 METs and a 14.5 km/h threshold effort 14.5 METs. Multiply by weight and hours for the burn. Worked example: a 70 kg runner covering 8 km in 48 minutes at 10 km/h burns 9.8 × 70 × 0.8 = 549 kcal — about 69 kcal per kilometer. The same runner jogging those 8 km at 8 km/h burns 485 kcal over an hour. That per-km figure (roughly 1 kcal per kg per km) is a handy cross-check for any distance.

1. 1

   Enter the run

   Distance and time — or distance and planned pace

2. 2

   Enter body weight

   Weight scales every calorie estimate linearly

3. 3

   Read the burn

   Total kcal, kcal/km and per-mile equivalents

• 1

  Use net burn (subtract ~1 kcal/kg/hour of resting cost) for strict diet math

• 2

  Hills add 10–20% — adjust manually for hilly routes

• 3

  Calories per km ≈ your weight in kg — quick sanity check

• Double-counting the workout in both food and fitness apps

• Using the treadmill’s calorie display, which ignores your weight history settings

• Assuming faster is always more: total burn depends on distance, not speed alone

• Ignoring walking breaks, which still burn 4–5 METs
