This is where I'm at right now as far as TT form--it's not all bad, since Charles Jacobs and I won the 2-man TT at Henderson in September. Riding with Charles was a bit of an epiphany, since I had never TT'd above 25mph, let alone averaged 27.4mph for 15 miles. I caught the bug then and there, and I plan to use the winter to really dial in my aero position and develop the fitness to ride a fast TT next year. I also upgraded to the newest Gyro TT helmet.
Here's my reference point: my teammate Ian Stanford, the reigning MN State TT champ for at least 2 years running, who just missed the podium for the Elite Nats TT this year. He drills a 40K TT in 52 minutes or less--25 miles at 29mph. He is a certified rocket. I realize that a lot of it is genes, but not all. I've bumped up the technology piece, and saw good results from that at Henderson, but just compare the photos: Ian looks wicked fast; I don't.
Now I'm going to try to dial in a more aggressive aero position over the winter, and do more TT specific work in the early spring. I might risk taking the edge off my sprint, but the years are doing that anyway. My fast twitchers just don't twitch quite as fast as when I ran the 220 in 1979. The only thing I can do better now than I did when I was 18 is suffer. So there.
Ian, no matter what I do, you've got nothing to fear from me, so thanks for the tips and the image of sheer speed. I'm dreaming every night of FAST.
