My boyfriend competed in a triathlon yesterday (temperature was under 40 degrees when they ran out from the pool to start the bike section) and he was the FIRST person off on the bike (about 40-50 people before him) smart enough to a) wear socks b) wear two layers of long-sleeves, including a softshell jacket (it was also windy!). The guy who won the event ran the whole thing shirtless, sockless, with essentially hotpants on. Looking at him made me shiver.
