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-per-mile rule of thumb changes slightly for walking. A study done by researchers at Syracuse found that men burned about 105 kilocalories/mile on average running a mile in 9 minutes and 30 seconds, and about 52 calories when walking the same mile in 19 minutes.For the women in the study, that burn was 91 and 43 calories, respectively. study done by researchers at Syracuse found that men burned about 105 kilocalories/mile on average running a mile in 9 minutes and 30 seconds, and about 52 calories when walking the same mile in 19 minutes.
