Thank you everyone. On race day I wear a skinsuit and calf high socks in lace shoes, with Velotoz covers. The bike gets a disc rear, all the bottles and carriers come off, and a solid 56T chainring for a better chainline to the middle cassette gears. Tires will be what is currently fastest, with latex tubes, 23mm front, 25mm rear.

Races are usually a pure out-back Time Trial, 10 miles or less. I find the whole "go as fast as you can" on a bicycle to be absolutely fascinating!
