Fast 50, halted.
I tried the Fast 50 for the first time, and was blown out the back by mile seven. 23-25mph average speed is too fast for me! My top speed on dead flat ground was 28.5mph. I can't sustain that to save my life.
Once dropped, I slowed down to a more reasonable (and enjoyable) 17-18mph and enjoy the orchards and farms south of Chico.
Psst: it was secretly fun to show up with the grumpy racer boys wearing a t-shirt and khaki shorts. ;-)
