Question: how many calories does an 8 mile run burn?
Answer: As a general rule, you can expect to burn roughly 100 calories per mile, Holland says, though exact numbers may vary depending on weight, sex, age and fitness level. In fact, some estimates dictate a 30-minute run at a speed of 6 miles per hour (a 10-minute mile) can torch 300–444 calories, depending on your weight.
