weeksy, i’ll point you at the start of the red or blue. After that follow the signs – you shouldn’t get lost! Any bike is fine – full suss, hardtail, rigid ss – whatever you have will be fine.
Weather – odd light shower? I wouldn’t panic and change tyres for that. Should be running fine. If it rains heavily it might be a bit greasy. It would have to be very heavy for the sessions to be cancelled at this time of year. Bring a jacket just in case. Lots of the trails are under tree cover anyway, so often you don’t notice a light shower.
Yes – most parents just go off and get a ride in, or read a book. We usually have one of the dbs checked parents helping out in one of the 2 sessions. I do one, phil40 sometimes the other. We also have young enduro racer lad who helps out too. So don’t worry about riding with the group – you go off and have some fun!
