If there's going to be a lot of other novice women there then maybe you could ask about whether they do any introductory sessions, prior to the actual racing so people can get a feel for it.

I'm sure there must be other women riders in your position who'd like to try but feel a bit apprehensive, and not eveyone has got access to a big gang of cycling mates they can practise group riding with. If they haven't got an taster session maybe you could suggest it? I'm sure people would be interested.

Whatever happens I'm sure you'll love it! Let us know how it goes.
