It has to do with the laws of motion. Momentum helps carry you up the stairs so you are exerting less physical force to help you get up the stairs. That is why you get more physical excercise when you walk up stairs vs running up stairs.

To get up the stairs faster. Or maybe they just like to run up stairs.

for exercise?
because theyre in a hurry?
because it's easier than walking because they have momentum as they run thereby requiring them put less energy into puling themselves up the next step.

take your IQ, divide it by the number of stairs you're running up, and hang yourself for asking such an assinine question

to excercise or because they are running late, or because they are Sylvester Stallone and they are making a movie.
