Calories Burned Running Calculator
Calculate exactly how many calories you burn running based on your weight, speed, and distance or duration. Uses validated MET values from the Compendium of Physical Activities. Includes race distance calorie estimates and food equivalents.

Running Calorie Science
Running is one of the highest calorie-burning activities per hour. The MET formula (Calories = MET × kg × hours) accounts for body weight because heavier people require more energy to move the same distance. Running's MET values range from 6.0 (slow jog) to 23 (sprinting) — among the highest of any activity.
The Afterburn Effect (EPOC)
Excess post-exercise oxygen consumption (EPOC) increases calorie burn for hours after running ends. High-intensity running creates an EPOC of 6–15% of the calories burned during exercise. An easy jog creates minimal EPOC; interval training and tempo runs create the highest afterburn.
Running vs Other Cardio
Running (at 6 mph) burns approximately 590 calories/hour at 155 lbs — more than cycling at 12 mph (563 cal/hr), elliptical (540 cal/hr), swimming moderate freestyle (423 cal/hr), or hiking (422 cal/hr). However, running's higher injury risk makes cross-training important for overall health.
How to Use Running for Weight Loss
To lose one pound of fat, you need to burn approximately 3,500 more calories than you consume. Running 3 miles burns roughly 300 calories at 155 lbs. Running 5 days per week creates a weekly deficit of 1,500 calories — equivalent to about 0.4 lbs of fat loss per week from exercise alone, before any dietary changes. Combining moderate calorie reduction with a consistent running program produces faster results. Start gradually to prevent injury: add no more than 10% to your weekly mileage each week (the "10% rule").
Frequently Asked Questions
A useful rule of thumb is approximately 0.63 × body weight in pounds per mile. At 155 lbs, that's about 98 calories per mile regardless of speed — heavier people burn more per mile. Speed mainly affects how many miles you cover per hour, not the calories burned per unit of distance.
Speed affects calories per hour significantly, but calories per mile stays fairly constant. Running 6 mph vs 8 mph burns more calories per hour because you cover more distance. However, running a fixed distance (say 3 miles) burns nearly the same total calories regardless of your speed — slower just takes longer to complete.
Running burns more calories per hour than walking, but calories per mile are similar. Running 1 mile at 6 mph burns about 98 calories (155 lbs); walking 1 mile at 3.5 mph burns about 83 calories — only 15 fewer. The real advantage of running is time efficiency: you cover the same distance in half the time.
Outdoor running generally burns slightly more calories due to wind resistance, varied terrain, and the effort of propelling yourself forward. Treadmill running at 0% incline is somewhat easier since the belt assists your leg turnover. Setting the treadmill to 1% incline closely approximates the calorie burn of flat outdoor running at the same speed.
