Each race lasts around 9 minutes.
A race ends when the racer in first position completes a specific number of laps depending on the track in use and the type of kart the racer is in. For example, an adult race on the Combined Enduro Track will end once 8 laps have been completed by the racer in first. Alternatively, on the Indoor Sprint Track, an adult race ends after 16 laps have been completed by the racer in first.
Almost all races will go the full distance before the time elapses. The other racers won’t be slowed to enter the pits until at least half a lap after the first racer crosses the finish line. This means if the supplementary racers are only half a lap behind the leader, they will finish the full laps at full speed also.
