The Saltaire TT series is usually 10k but the race I went to happened to be changed at the last min to 24k because they wanted to get some practice for the state TT finals on Saturday. The only problem I had was that I didn't bring any water thinking I was only going 6 miles. The wind is intense and the dirt in the throat really hurt but there is 0 elevation so very fast.
My stats: 14.20 miles 34:50 24.4 MPH
