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.
The calories burned jogging in place varies depending on the person's weight, metabolism, intensity and time of their workout. Discovery Health states that jogging in place for 40 minutes burns 363 calories for people that weigh 150 pounds, while it burns 484 calories for those that weigh 200 pounds.
