Calories Burned. A half mile is a relatively short distance to run, so you shouldn't expect a big calorie burn. According to the website Cool Running, a 200-pound person will burn 79 calories running half a mile. A 175-pound person will use less energy, burning just 69 calories per half mile.
The average 150 pound runner burns 100 calories per mile. This number will vary depending on your weight and the pace you run at. I burn much more than 100 calories per mile because I weigh more than 150, and I run a decent pace. The calories burnt link can help you determine how much you burn off when exercising. One pound is roughly 3500 calories. Don't worry though, you don't have to run 35 miles to lose one pound.
