The whole race consist of a 1000 miles (not really 1000, it was 1300km) mainly on public roads. There were 2 special primes in kart tracks, but only a few laps!!!
This kind of races are not about top speed, it is about average speed (almost always around 60 miles) where the winner is the one who is close to the indicated speed!
I know I need a taller roll-over, because of the one fitted (too short) I was almost prohibited from racing this kart track!!!
