I don't know if it will be more slipery then it was Saturday, but if its the same, I was thinking maybe doing a half a lap, climb the Spanky then do some interval training on Constitution. If its too slick we can just head to constitution. I dont feel like riding in my kitchen tonight.
If conditons are like Early saturday, it should make for some good bike handling skills training. Single speeds will have a rough time on the climbs though.
