We used to have a Tue/Th afternoons group ride that left from a local HS, crossed the river and meandered around the rural fields across the river before returning. I'd very occasionally join and try to hang with the pack, which usually included Cat 2 and 1 riders and the occasional pro, wintering here. At some point every ride, the pros would simply drop the pack and motor on, never to be seen again.
Part of my education that we are indeed built differently from those folks. Okay, me at least.
When Amgen came through town I occasionally saw a team out and about on training rides, but it's not as though I ever had a "Hey, that was Cavendish!" moment. Miss that race.
