How Far Did They Run?

When I first saw this movie when the coach challenged the team at the start of the season, I always thought they ran forever. However I always wondered how much they ran. Being that they didn't take football seriously and a lot of them had trouble doing 20 push ups, I'm going to say she ran about 4 to 5 miles tops.

I think I'm being generous. Anyone have any guesses? And yes I know it's a movie and it's fake. I was just wondering what type of message the movie was trying to convey w/ all the running.
