I realise that there are a few posts already on this - but I have just moved to London and looking for a road club to join. I was hoping to pop along this Sunday (9th) if possible?
I currently ride with a club in North Devon and tend to ride out with their 'coffee & cake' group on a Sunday that covers 40-50 miles at 13-15mph - which takes in to account the lovely Devon rolling hills. I see that you have three groups that go out on a Sunday - A, B, and C - so having had a look at your speeds I would probably be best to go out with C first?
Let me know if it is possible to join you this Sunday and your recommendation of group.
