sorry for the delay in a reply but ive been away on holiday having fun....

It very much depends what sort of club you want to start up.
Firstly you need a committee and then you need to sort out your insurance which is best done by affiliating to BC.

Let me know if you are serious about starting a club and i can give you some contacts.

How can I help, your first point of call should be to affiliate with British Cycling this will give you the most important thing insurance cover and form a committee.
If you need any help with any of this please feel free to ask.
