The most races started inside a single hour. Sleep is not a factor here.
Across every confirmed race — including races that were never published.
This board counts races in a one-hour window, so it is not split by car class.
These are for fun. We work them out from what the game reports while a race is running, and we keep them as accurate as we can — but they are not exact and we do not guarantee them. If one looks wrong to you, tell us.
