Well, not really, but I did have a great dry run on the TT course I'm riding in Sept. on my Cdale Slice. It's rolling hills, and after 10-15 mins. on this course grinding up gradual upgrades into the headwind I'm thinking 'it's going to be tough to average 20mph here'.
The downhills on this road were friggin SCREAMING on a TT bike. 30-40mph for considerable stretches. I ran out of gear to pedal for hundreds of meters a couple of times and just had to tuck and roll. Man that was a blast. TT bikes are in hyperdrive going down a hill. Amazing. I'm a speed junkie, no fear, loved it. In the end I actually averaged about 21mph for 14 miles. That will be faster on race day with Zipps, TT helmet and race day adrenaline.
Dr. W. will average 28mph : ).
I don't care. I love the whole TT thing. Right up Pcad's alley. Like I said you can't get dropped in a TT. Besides, I'm already not the slowest TT guy in NY State (I'm ranked like 98th out of 140 or so 35+ dudes). Next step: get up into the top half of the Master's rankings. That's really cool: training for races and trying to crawl up that USCF ranking ladder.
Anyway, it was Big Fun, and I did enjoy the course. I'll ride it at least three more times prior to race day. I know the road fairly well, but on TT day I'll have ridden it on my TT bike at least four times. This ROCKS. Never thought I'd like the TT thing so much. Very cool. A welcome new focus for my riding, and an outstanding way to stay involved in racing as I get older.
