Raleighdon and I rode the tdt TODAY. we decided on the 80 mile route since 109 seemed overwhelming to yours truly.
we started at 9am and rode like bandits. we finished in 5 hours and 13 minutes of riding time (i cannot believe i went this fast)
my personal average was 15.8mph!!

i will tell you all more tomorrow. i'm too tired. it was very hot, but this dry air coupled with very very gentle slopes and a bit of altitude makes for a much faster ride.
