Wow, what a ride, very fast, I led the group through Cisco then stayed near the front in a group of eight guys, including Dave, Jeff, and others that I don't know. Although I met another Jeff for beer and pizza later and he told me about Chris Horner youtube updates on the Vuelta, and we shared our reflections on the Tour de France. But that's not important. He was in a group of four that went out faster than us, and then we came across them on Eldridge where he had flatted. Anyway, I felt good on South Acton road, staying near the front and then started getting dropped a little on hill on Taylor, catching up to everyone by Finn, but eventually got dropped going onto Codman Hill Road, by a front group of three or four guys. My psoas on left was a little sore, but not my hamstring. I felt good probably because it was flat, not hills. My bike needs new tires and a cleanup for sure.
