Shadow,
I have dabbled with a couple of local clubs around Chichester / Littlehampton but find them either too serious or just happy to go out for a Sunday bimble. I 'belong' to a small informal group / club near to Yapton which has 'members' from across West Sussex and one in Sheffield. It varies in numbers for group rides but there is usually 6 or so of us out and about.
Quite often do day rides out and have recently done Leith Hill and Box Hill from home and looking forward to doing the IOW again soon now that restrictions have been lifted.
How about yourself?
