I get the impression this kind of "I can't do my thing anymore so I'll cycle" seems kinda common. That aussie AIS (?Amy Gilette?) roadie that got killed in Germany a couple of years ago was a former rower and switched to cycling to continue competing.

At least the track is getting press. I don't think it's just the US anymore that has a waning affection for track racing as the IOC dropped both the men's & women's 500m track event from the 2008 Olympics anyway... to make room for... eeewwww... BMX.
