Miles to Calories Burned Calculator
A common rule of thumb says running burns about 100 calories per mile, but your real number depends mostly on body weight: a 120 pound runner burns around 90 calories per mile, while a 180 pound runner burns closer to 135. This running calorie calculator converts miles run into calories burned using your weight, at 0.75 calories per pound per mile, which lines up with published exercise research. Enter your distance and weight to see your total burn plus your personal calories per mile.

Calories per mile by body weight
Using the standard rate of 0.75 calories per pound per mile: 120 lb burns about 90 per mile, 140 lb about 105, 160 lb about 120, 180 lb about 135, and 200 lb about 150. Multiply by your distance for the run total: a 160 pound runner covering 5 miles burns roughly 600 calories.
These figures assume steady running on flat ground. Add 10 to 20 percent for very hilly routes, and remember that beginners often burn slightly more than experienced runners because their form is less efficient.
How to burn more on your runs
Hills and intervals raise the intensity, which raises calories per minute, though per mile totals stay close. The simplest lever is distance: an extra mile always adds roughly your per mile number, whatever the pace.
Consistency beats heroic single runs. Four moderate runs a week burn far more over a month than one exhausting long run followed by six rest days. And pair running with sensible eating: exercise estimates run optimistic, so most people lose weight faster when they treat food and training as a team rather than trying to outrun their diet.
Frequently asked questions
How many calories do you burn running a mile?
Roughly 90 to 150 calories per mile for most adults, depending on weight. At 0.75 calories per pound per mile, a 120 pound runner burns about 90, a 150 pound runner about 112, and a 180 pound runner about 135. The popular 100 per mile figure is a decent average but hides the weight difference.
Does running faster burn more calories per mile?
Per mile, speed changes surprisingly little. Distance and body weight drive the total, which is why a slow 5 miles and a fast 5 miles burn nearly the same. Faster running does burn more calories per minute, because the intensity is higher.
What affects calorie burn besides weight?
Hills and rough terrain raise the cost, as do heat, humidity, and headwinds. Fitter runners are slightly more efficient and burn a little less for the same run. Body composition matters too: muscle tissue costs more energy to move than fat.
Does running on a treadmill burn fewer calories?
Slightly, yes. Outdoor running adds wind resistance and terrain variation, which cost extra energy. The difference is small for most runners. A treadmill is fine for consistent training; just know outdoor numbers run a touch higher.
Running vs walking: which burns more per mile?
Running burns about 30 to 40 percent more calories per mile than walking, because of the higher intensity and the bouncing motion. Walking is still excellent exercise; it just costs less energy per mile covered.
Should I eat back my running calories?
For weight loss, eat back only part of exercise calories, or none, since estimates tend to run high and it is easy to overeat the reward. For performance or muscle gain, fuel the work: eat enough to recover well and train hard the next day.
How accurate is this calculator?
It is a solid estimate based on the research backed rate of about 0.75 calories per pound per mile on flat ground. Real burn varies with terrain, weather, and running efficiency, so treat the result as accurate within roughly 10 to 20 percent, not to the single calorie.
