That cycling track is pretty bad to be honest. I know Blockland vehicles don't quite follow the physics of real racing bikes, but it should probably be quite a lot bigger and maybe have a slight outwards gradient like a real velodrome.
Then again, the World Record for persuit is ~14.53 seconds/lap, so I guess that size you have there is about right.
Hehe.
As for event signup, I'll sign up if you actually disclose a schedule of events, even if it's approximate with a day and a time to within 4 hours or so.
