Hi, I have done virtually all of my riding solo for the past several years. I'd like to join a club or at least do some group rides to get to know more like minded folks, but I want to make sure that I follow the rules or at least do some basic research before jumping into a group ride with those that have experience.

Interestingly, I haven't been able to find a good answer in the internet for the following and haven't been able to surface anything when I do a forum search. Group rides are typically labeled A, B or C. While I realize that the groups denote different MPH paces (at least I think!?!) and to soem extent fitness.....what are the break points? For example, is the C group for 14 MPH and under?

Ha, what a n00b I am. But everyone needs to start somewhere and you guys are cool.

But I do know the meaning of HTFU and I'm trying to do that.
