I think it all has to do with the intention of the group or club itself. I ride with a club on the 2nd and 3rd Saturday of each month and there is normally one group; LETR or Let's Enjoy The Ride. Once in a while some faster cyclist come out and they normally go off on their own. They do the 17-20+ mph ride and the rest of the group does a 10-14 mph ride. The faster group is all road bikes and the slower, LETR group is any bike that you have is welcome. I have ridden with the faster group once or twice but prefer riding with the LETR group as the ride is more of a camaraderie ride then anything else. There are other group and club rides in Tampa, but most of them are pace-line rides on city streets and back roads. I don't like doing pace-line rides where there is a lot of traffic so my pace-line rides are done on a bike path in a county park.
