Just a quick question. When the group picks up the pace a lot near the end, what are you supposed to do? Sit back with some of the slower folks in the group ride, or go with them if you can stay up. I don't think they were sprinting, it was fairly easy for me to keep up, but I wasn't sure if this was normal or if my baggy shorts, steel frame, and poor technique was embarrassing and I thought they might be trying to get away from me.
