First we build the machine with which we can race. We organise teams who receive the elements and gokart building can start. Teams have ca. 1 hour to build a not just nice, but also a fast vehicle. As soon as the vehicles are ready, race can begin. 1 machine – without engine -, 1 driver – of course with a helmet -, instead of 4 horse-power 4 colleagues/ friends will give us the speed. During the time-race racers drive on a slalom court then comes 3 circles in the ring. They have to change wheels, put petrol in the car and compulsorily stop at the boxes.
