I've been searching the internet, trying to find some info, it is a flat semi oval, MC track, they say 500cc motorcycles turn 4 laps, in 50 seconds, but nothing about size, there are some videos on there, of the racing, which gives some idea of size, and shape, I'm guessing if you ran Madison, you'll be close on gear, just a wild guess, but not anything like some of the guestimates I've heard.
