[link=http://sports.espn.go.com/oly/news/story?id=5718372]ESPN's article about it.[/link] Fran Crippen, 26, was an accomplished open water swimmer. From what the article says, the temperature of the water must have been in the mid to high 80s, which is really warm to be racing in. Sorry to hear about this - it's always a shame when someone that young dies. At least it was doing what he loved. As a former swimmer (in elementary school, mind you ) I think that open water swimming is crazy - I'd never want to swim anything more than 500 meters at a time. It certainly is a challenging sport, and it will be without a good competitor. RIP.
