i dont like when guys fall over on the track. go under the bleachers and lay or sit all you want, but as long as youre on the track, with people all around, dont just sit there.
that being said, when a guy averages 64 for a 5km, and closes in 34, he obviously emptied the tank out there. i sitll dont like it though when a guy sits there for mintues after.
i remember a wetmore qoute on ritz after his ncaa cross victory. something to the effect of ritz was laying in pain in the team tent 15 minutes after the race, barely able to stand he had run so hard.
