Running vs. Walking. What burns more calories?

Alot of people are not familiar with the fact that you actually burn the same amount of calories if you run vs. walk the same distance. The difference is, of course, that running you do it faster and have a longer afterburn. But the factors for burning calories are roughly: time and weight. So the heavier you are and the longer you exercise, the more calories you burn. That is why you have to alter your exercise routine once you start losing weight.
