I know that many cross country teams hold a "Beer 2-mile" race at the end of the season. It's a 2 mile race (obviously) but the catch is that at every station you have to down a can of Natty Light. Tossing your cookies DQs you. And after you cross you have to keep it down an additional 5 minutes for your time to be recorded.

Similarly some teams do a Coke 1 mile around a track. Contestants chug a 2-liter of Coke and run like hell for a mile. Again, puking DQs you.
