The National Sports Center in Blaine, and the NSC Velodrome, are offering indoor criterium racing on grass this winter.
It’s a 5 race series, with 3 races each night. Racers are allowed to bring any bike they want, although it’s to be assumed that cyclocross bikes are likely the best handling. I have to assume that spectating is possible, although I haven’t yet tried and the web page for the series doesn’t mention spectators at all.
I’m hoping spectators are feasible, because this sounds freaking awesome to watch, even if it’s sort of after the littlest racefan’s bedtime.
