Just witnessed a Jack Daniels 2-Mile, in which you take a shot of JD at the start of each lap (8 shots in all) of a two mile. Shots were taken from pre-filled paper cups so they could be taken on the run, but probably added about 1.5-2 seconds per lap (slowing to grab the cup and drink, etc.).
winner ran 9:53 (without puking until about 15 seconds after finishing)
eh?
