Answer 1

Most of the calories you burn go toward basic life/maintenance. Making new proteins, moving molecules around in your cells, cell division, all that stuff. This is happening constantly in your entire body and needs a ton of energy.

Running is actually quite easy for your body and is only a little bit of extra energy on top of all that, so it only requires a few extra calories relative to what you burn just to survive the rest of the day.
