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.
Half an hour of jogging at a 5-mph pace (that's 12-minute miles) burns about 256 calories. Cranking it up to 7.5 mph (8-minute miles) raises your burn to around 403. Running is a good example of how you can really play with the duration and intensity of your workout, Procida said. If you're going to run all out, run for 30 minutes.
