Maybe a tip for the ones who want to join a race.
I went to Oldenzaal 2weeks ago, where they had a race which lasted an hour. Once every 2months or so, they are hosting a race like that.
You had: 8minutes of qualifying, and immediately after that, the 1hour race. It was much fun, and our winner did 83 laps.
It costed 35euro's which is very cheap for an hour of racing.
They do have a max capacity of 40racers though. 2groups of 20.
