Ultra-distance triathlon

For those seeking the ultimate triathlon test (and maybe a touch of masochism) these events currently stand as the pinnacle of endurance sports.

Women have always crushed it at endurance events, but Michelle Vesterby’s recent dominant overall win at Ultraman Arizona has us asking - why are women so darn good at going super long?

The inaugural Leadman Epic 250 event will entail a 5K swim, 223K bike and 22K run and will take place May 14, 2011, in Las Vegas, Nev.
