Dont worry about all the do’s & dont’s.
Most of it is just common sense, its just really there to help total novices, which i doubt you are.
Just pick a ride that you think is at your level and go along and see how it goes.
It you dont fancy that, then put a msg up on the message board and ask about any other runs that people are going out on.
The saturday runs are the most popular and you can sometimes get 50+ riders on one run, but if this happens then the group will get split up latter.
It can be a bit daunting at first (we’ve all be there), but after a few runs you’ll get the hang of it.
