Yeh CTC ..... sounds about right, they are all eccentric........
They also can vary in speeds and club ride policy, some dawdle between pubs [ possibly stopping to brew up by the side of the road using some 1940's petrol stove they bought in an army surplice store] and some are quick and might stop every 100 miles or so for a bit of cake.
Our club though small does cater for most riding, tt's are the mainstay but the club rides are not chain gangs and always wait for the slower riders. We do a bit of MTB night riding in the winter and members are often off doing audax or road racing or touring.
You might have to try a few local clubs out before finding one suitable, this is the 3rd that I have ridden with and they haven't chucked me out yet
