Anybody can enter a JCRC event. Best to register online first and get a registration number for yourself.
You will need to allocate a team as well which may also have its own seperate #. No problems if you start a new team name.
James, not sure I have the legs to do that. Certainly don't have the legs I had in May. I've been focussing mostly on hillclimbing since then. I have a hillclimb on Monday and after that I want to focus on getting some speed practice - hopefully my wife will agree to a bit of motorpacing. Ever tried it?
