I know nothing about club rides but it all seems to be taken terribly seriously doesn't it.
I thought that, but on attending a laps of Richmond Park session with Kingston Wheelers (as a new member) a couple of days ago, I was pleased to witness the following...
"K2 riders? What? One person? Come on, people... ok, K2 riders all THREE of you, over there by the sign."
"K3's ? Really ? OK, K3's down by the tree.. Why is everyone still here?
Are you really ALL riding K4? Right, all K4s over there"
I joined a very nice K4 group and managed to keep up (ish) so that went well. And the pint at the pub afterwards was hugely enjoyable.
