If there is such a requirement, does it actually have to be from running or does using a Sedgeway (I think I screwed that spelling up) count?

I know when I was in college, the football coach had a timed mile for the players. Certain positions were required to run under the prescribed times, and if they failed, then they had to run extra stadium steps on a daily basis. However, we did "exempt" a couple because they were able to swim the equivalent time or something other. Wonder if there would be such an exemption? Just curious.
