Figuring out how many calories you burn when running is, on a simple level, a fairly straightforward calculation. Most experts (and lots of studies) suggest that a person of average weight burns about 100 calories in a mile of running.
You see the question how many calories do you burn running a mile asked a bit when looking at running as an exercise related to calorie counting. I thought I would use this calorie burn calculator to put together a table of the calories burned running a mile. An estimate of the calories burned running can be formed, based on the weight of the runner and how fast they are running.
