I once raced a former National ranked downhill skier down a hill (skiing). (I'm big so I figured gravity would help a little). By the time I had scared the Sh##t out of myself and got down the mountain, he had removed his skis, gone into the bar, ordered us both a beer, and was sitting waiting.
Pros are very good at what they do. The one interesting thing I have heard about some bike racers are that they are not very good other sports.
