How many calories does running burn?
Running burns approximately 60–80 kcal per km for an average-weight adult, depending on pace, body weight, and terrain. Heavier runners burn more calories for the same distance; faster running burns more per minute but a similar amount per kilometre.

Calorie Burn Formula: Calories = MET × Weight (kg) ÷ 60 × Time (minutes)
MET values by running speed: Jogging (6–8 km/h) = 7–9, Running (8–10 km/h) = 9–11, Fast running (10–12 km/h) = 11–12, Racing pace (>12 km/h) = 13+
Calories burned by race distance
| Distance | 70kg at 6min/km | 70kg at 5min/km | 80kg at 6min/km |
|---|---|---|---|
| 5K | ~330 kcal | ~380 kcal | ~375 kcal |
| 10K | ~660 kcal | ~760 kcal | ~750 kcal |
| Half Marathon | ~1,380 kcal | ~1,600 kcal | ~1,575 kcal |
| Marathon | ~2,760 kcal | ~3,200 kcal | ~3,150 kcal |
EPOC — the afterburn effect
Running also increases calorie burn for hours after you finish through Excess Post-Exercise Oxygen Consumption (EPOC). After high-intensity running, EPOC can add 6–15% to total calorie burn. After moderate-pace running, the effect is 3–7%. For a 600 kcal run, this adds 40–90 additional kcal over the following 12–24 hours.

Frequently asked questions about running and calories
Does running faster burn more calories? Running faster burns more calories per minute but a similar amount per kilometre. A 5K at 5 min/km takes 25 minutes; at 7 min/km takes 35 minutes. The faster runner burns slightly more per km due to the higher metabolic demand of sprinting, but the difference is modest — distance matters more than speed for total calorie burn in endurance running.
Can you outrun a bad diet? Very difficult. Running a 5K burns approximately 300–400 kcal — equivalent to a medium latte or a couple of biscuits. Exercise is important for health, but diet is the more powerful lever for weight management. The most effective approach combines moderate caloric deficit with regular exercise.

How many calories does running burn by distance and pace?
| Distance | 70kg at 6 min/km | 70kg at 5 min/km | 80kg at 6 min/km |
|---|---|---|---|
| 5 km | 330 kcal | 375 kcal | 375 kcal |
| 10 km | 660 kcal | 750 kcal | 754 kcal |
| Half marathon (21.1 km) | 1,392 kcal | 1,581 kcal | 1,588 kcal |
| Marathon (42.2 km) | 2,785 kcal | 3,165 kcal | 3,178 kcal |
What are the MET values for different running speeds?
| Pace | Speed (km/h) | MET Value | Intensity Level |
|---|---|---|---|
| 10:00 min/km | 6.0 | 7.0 | Light jog |
| 6:00 min/km | 10.0 | 10.0 | Comfortable run |
| 5:00 min/km | 12.0 | 11.5 | Tempo pace |
| 4:00 min/km | 15.0 | 14.0 | Fast / race pace |
Training calorie needs by race goal
Weekly additional calorie burn from running training (above baseline TDEE):
| Race Goal | Weekly Mileage | Weekly Extra Kcal |
|---|---|---|
| 5K fitness | 15–25 km | 990–1,650 kcal |
| 10K competitive | 30–50 km | 1,980–3,300 kcal |
| Half marathon | 50–70 km | 3,300–4,620 kcal |
| Full marathon | 70–100 km | 4,620–6,600 kcal |
The afterburn effect (EPOC) from running
EPOC (Excess Post-Exercise Oxygen Consumption) means your body continues burning extra calories after your run. After moderate Zone 2–3 running: EPOC adds approximately 6–8% to workout calorie burn for 2–4 hours. After high-intensity intervals (HIIT): EPOC adds 10–15% for up to 12–24 hours. On a 600 kcal run: an extra 40–90 kcal burned during recovery.
Frequently asked questions about running and calorie burn
Does running speed or distance matter more for calorie burn? Distance matters more than speed. Running 10 km at 5 min/km burns only 5–10% more than 10 km at 6 min/km — because you cover the same distance, just faster. For fat loss, total weekly distance is the primary variable, not pace.
How long should I run to burn 500 calories? A 70 kg person burns approximately 600–700 kcal per 10 km at moderate pace (6 min/km), taking about 60 minutes. To burn 500 kcal: approximately 50 minutes running. Lighter runners need slightly longer; heavier runners reach 500 kcal faster. Running on hills adds 15–25% to calorie burn.
Can running every day lead to overtraining? Yes. Running daily without rest days increases injury risk (shin splints, stress fractures, IT band syndrome). Most coaches recommend at least 1–2 full rest days per week and 1–2 easy recovery days. Alternate hard and easy days — never two consecutive high-intensity days.
Calorie burn by running speed and body weight
The approximate calories burned per kilometre of running is about 0.7–0.8 kcal per kg of body weight (regardless of pace — faster running burns similar calories per km, just in less time). A 70 kg runner burns roughly 49–56 kcal per kilometre.
| Body Weight | 5 km run | 10 km run | Half marathon (21.1km) | Marathon (42.2km) |
|---|---|---|---|---|
| 55 kg | ≈187 kcal | ≈374 kcal | ≈790 kcal | ≈1,580 kcal |
| 70 kg | ≈245 kcal | ≈490 kcal | ≈1,034 kcal | ≈2,068 kcal |
| 85 kg | ≈298 kcal | ≈595 kcal | ≈1,256 kcal | ≈2,512 kcal |
| 100 kg | ≈360 kcal | ≈720 kcal | ≈1,519 kcal | ≈3,038 kcal |
Running for weight loss: realistic expectations
To lose 1 kg of body fat, you need to burn approximately 7,700 kcal more than you consume. A 70 kg person running 5 km daily (490 kcal/day deficit, assuming diet stays constant) would theoretically lose 1 kg in about 16 days. In practice, running often increases appetite — studies from Université de Lethbridge find that appetite hormones ghrelin and PYY often compensate partially. Combining running with a moderate calorie deficit (300–500 kcal/day from diet) is more effective than running alone for sustained weight loss. Target: 150–300 minutes of moderate-intensity running per week for health benefits (WHO guidelines). Related: Calorie Deficit Calculator · TDEE Calculator
