Formula
Calories = MET x Weight(kg) x Duration(hours)
Where MET is the Metabolic Equivalent of Task assigned to running at a specific speed, Weight is body mass in kilograms, and Duration is exercise time in hours. MET values range from 6.0 for slow jogging to 16.0 for competitive sprinting, and are adjusted upward for incline running.
Worked Examples
Example 1: Morning 5K Jog
Problem:A 70 kg person jogs 5 km in 30 minutes on flat terrain. How many calories are burned?
Solution:Speed = 5 km / 0.5 hours = 10 km/h\nMET for 10 km/h running = 9.8\nCalories = MET x weight x time in hours\nCalories = 9.8 x 70 x 0.5 = 343 calories\nCalories per km = 343 / 5 = 68.6 cal/km\nFat burned = 343 / 7700 x 1000 = 44.5 grams
Result:Total Calories: 343 | Per km: 69 cal | Fat burned: 44.5g
Example 2: Hill Running Workout
Problem:An 85 kg runner covers 8 km in 45 minutes with a 3% average incline. Calculate calorie burn.
Solution:Speed = 8 km / 0.75 hours = 10.67 km/h\nBase MET for ~10.7 km/h = 10.5\nIncline adjustment = 10.5 + (3 x 0.1 x 10.5/10) = 10.5 + 0.315 = 10.815\nCalories = 10.815 x 85 x 0.75 = 689.5 calories\nCalories per km = 689.5 / 8 = 86.2 cal/km
Result:Total Calories: 690 | Per km: 86 cal | MET: 10.8
Frequently Asked Questions
How does running speed affect calories burned?
Running speed has a significant impact on calorie expenditure because faster running requires more energy per minute. At a slow jog of around 8 km/h, the MET value is approximately 8.3, while sprinting at 16 km/h pushes the MET to about 12.8 or higher. This means a 70 kg person jogging for 30 minutes burns roughly 290 calories, but running at a fast pace for the same duration could burn over 450 calories. The relationship is not perfectly linear because biomechanical efficiency changes at different speeds. Faster running also increases post-exercise oxygen consumption, meaning you continue burning extra calories after your run ends.
Does body weight affect how many calories you burn running?
Body weight is one of the strongest predictors of calorie expenditure during running. Heavier individuals must move more mass against gravity with each stride, which requires proportionally more energy. A 90 kg runner will burn roughly 30 percent more calories than a 70 kg runner covering the same distance at the same pace. This is why running is particularly effective for calorie burning in heavier individuals. The calorie calculation uses the formula MET times body weight in kilograms times duration in hours, making weight a direct multiplier. Interestingly, research shows that calories burned per kilometer is relatively constant for a given weight regardless of speed.
How does running on an incline change calorie burn?
Running uphill dramatically increases calorie expenditure compared to flat terrain. For every 1 percent increase in grade, energy cost rises by roughly 3 to 5 percent. A 5 percent incline can increase calorie burn by 15 to 25 percent compared to running on flat ground. This happens because your muscles must work harder to lift your body against gravity with each stride. Hill running also recruits more muscle fibers, particularly in the glutes and hamstrings, which adds to total energy expenditure. Treadmill users can take advantage of this by setting an incline to simulate outdoor conditions and boost their calorie burn without increasing speed.
Is running more effective for burning calories than walking?
Running burns significantly more calories per minute than walking, but the difference per unit distance is smaller than most people think. A 70 kg person walking a kilometer burns about 65 calories, while running the same kilometer burns approximately 80 to 95 calories. The main advantage of running is time efficiency since you cover more distance in less time. In 30 minutes of running you might cover 5 km and burn 350 calories, while walking covers about 2.5 km and burns roughly 160 calories. However, walking has lower injury risk and is more sustainable for beginners. For maximum calorie burn in limited time, running is clearly superior, but consistency matters more than intensity for long-term results.
