I don't think I go fast honestly, in reality technically 65-70 is fast i would also assume most bike riders consider this quite slow. I don't think I'm riding too fast but then again that's why I made this post to see when you realize what too fast is.
I've had a bad itch lately wanting to go to the track I have to find one local or someone local ish I can attend with. Cross country ninjette track weekend?
