Just catching up on this thread so apologies for replying to a v.old post, especially since this is a bit off-topic, but I thought this was interesting enough to merit it...
I've skated in the past and young Bolletta skates now so I take an interest in the ice events. I can believe that the qualities of a decent TTer or track-cyclist would work well for the ice track events.
Connie Carpenter-Phinney started out as a speed skater before moving to cycling - road rather than track. And she was frikkin' awesome at both.
In fact, she is one of a number of athletes who have competed at both the summer olympics in cycling and the winter olympics in speed skating. Laurine Van Riessen rode on the track for the Dutch team at the 2016 olympics having previously competed at the winter games in speed skating.
Cross country skiing is another popular sport among cyclists and a good few athletes have doubled up at the winter/summer games in those sports.
Also Thibaut Pinot competed in a cross country skiing race earlier this year.
