Running Calories Burned Calculator
Find out how many calories you burn running. Enter your weight, distance and time or pace, plus any incline, to see total calories, calories per kilometre and per mile, using the ACSM running equation.
Running burns approximately 1 kcal per kilogram of body weight per kilometer on flat ground (~1.6 kcal/kg/mile). A 70 kg runner burns roughly 70 kcal per kilometer (350 kcal for a 5K and 700 kcal for a 10K).
Running Calories Burned

Running Intensities & Metabolic Equivalents
| Running Pace | Metabolic Demand | Physiological Purpose |
|---|---|---|
| Easy Recovery Jog (8 km/h / 5.0 mph) | ~8.3 METs | Light aerobic base building |
| Standard Aerobic Run (10 km/h / 6.2 mph) | ~10.0 METs | ACSM metabolic running baseline (~1 kcal/kg/km) |
| Tempo / Threshold (12 km/h / 7.5 mph) | ~11.8 METs | Lactate threshold endurance training |
| Fast Pace / Intervals (14 km/h / 8.7 mph) | ~13.3 METs | High cardiovascular and anaerobic glycolytic demand |
Equation: VO2 = 0.2×Speed + 0.9×Speed×Grade + 3.5 ml/kg/min (ACSM Guidelines for Exercise Testing and Prescription).

How to use Running Calories Burned Calculator
- 1Enter your body weight in kilograms or pounds.
- 2Input your run duration and running speed (or pace).
- 3Optionally apply treadmill incline or the 1% grade rule.
- 4Inspect total gross calories, net active calories, and fat-equivalent energy burned.
ACSM running equation
VO2 = 0.2 × Speed (m/min) + 0.9 × Speed × Grade + 3.5 ml/kg/min. Unlike walking, running involves a ballistic flight phase where vertical oscillation requires sustained muscular work.
The 1% treadmill rule
Research by Jones & Doust (1996) demonstrated that setting a treadmill to a 1% gradient accurately replicates the energetic cost of outdoor road running by compensating for lack of air resistance.
Frequently Asked Questions
How many calories does running 1 km burn?
Roughly 1 kcal per kg of body weight, so about 70 kcal for a 70 kg runner.
Does running faster burn more calories?
Per kilometre, not much; per minute, yes. Distance and body weight matter most.
How many calories does a 5K burn?
About 300 to 450 kcal for most adults.
