hora – go through the accreditaiton process. Then you have the right to ride at the SQT (Structured Quality Training, donchaknow) sessions. These are for any accredited rider, whether in a club or not.
It is also hired out to clubs for their own track nights (my club had its annual night there on Saturday), and these are popular enough to mean clubs need to book a year in advance. However, they are essentially the exception, with the SQTs (and taster, etc.) sessions being the dominant activity.
So, get into the accreditation programme, and then you get to ride properly, get fit and enjoy it without having to wear club kit and shave your legs (mind you, you probably shave your legs anyway…).
