How MET values estimate calorie burn
A MET (metabolic equivalent) expresses exercise intensity relative to rest. Calories burned ≈ MET × body weight in kg × hours. Running METs range from about 7 at an easy jog to 16+ at fast race pace.
Why body weight drives calorie burn
Running is a weight-bearing activity, so the energy cost scales almost linearly with how much mass you move. A heavier runner burns more calories covering the same distance at the same pace than a lighter runner, which is why two people on the same run can have very different totals.
A useful rule of thumb is that running burns roughly 1 kcal per kilogram of body weight per kilometre. A 70 kg runner therefore burns about 70 kcal per kilometre, or close to 700 kcal over 10 km, largely independent of pace.
Distance matters more than speed
Because the per-kilometre cost is fairly stable, total distance is the biggest lever on calories burned. Running faster burns more per minute but you finish sooner, so the totals for a given distance end up similar. If your goal is energy expenditure, adding distance reliably beats adding speed.
Calories burned per 30 minutes of running
| Pace | Speed | 60 kg | 75 kg | 90 kg |
|---|---|---|---|---|
| 7:30 /km | 8 km/h | 250 | 310 | 375 |
| 6:00 /km | 10 km/h | 300 | 375 | 450 |
| 5:00 /km | 12 km/h | 345 | 430 | 520 |
| 4:17 /km | 14 km/h | 385 | 480 | 575 |
| 3:45 /km | 16 km/h | 435 | 545 | 650 |
MET-based estimates for 30 minutes at a steady pace; heavier runners and faster paces burn more. As a rule of thumb, running costs about 1 kcal per kg of body weight per kilometre, largely independent of pace.
Frequently asked questions
How many calories does running burn?
A 70 kg runner burns roughly 600–750 calories per hour at a moderate pace. Calories scale with body weight and speed.
Does running faster burn more calories?
Yes, per minute. Faster running has a higher MET value, so you burn more calories per minute, though you may run for less time.
Does running burn more calories than walking the same distance?
Slightly, but less than people expect. Over the same distance the totals are closer than they feel, because walking simply takes longer. Running wins on calories per minute, walking is gentler on the joints.
Are the calories on my watch or treadmill accurate?
They are estimates, usually within 10-20%. Treadmills that do not know your weight are the least reliable. Use any single number as a consistent reference rather than an exact truth.
Should I eat back the calories I burn running?
Partially, if at all. Exercise calorie estimates tend to run high, so eating all of them back can stall weight loss. Replacing roughly half is a safer starting point if you are managing weight.
How many calories does a 30-minute run burn?
It depends on your weight and pace, but a 75 kg runner burns roughly 310–545 calories in 30 minutes depending on speed, as the table below shows. A useful shortcut is about 1 calorie per kilogram of body weight per kilometre.
