Endurance racing is a form of motorsport racing which is meant to test the durability of equipment and endurance of participants. Teams of multiple drivers attempt to cover a large distance in a single event, with participants given a break with the ability to change during the race. Endurance races can be run either to cover a set distance in laps as quickly as possible, or to cover as much distance as possible over a preset amount of time.One of the more common lengths of endurance races has been running for 1,000 kilometres (620 mi), or roughly six hours. Longer races can run for 1,000 miles (1,600 km), 12 hours, or even 24 hours. Teams can consist of anywhere from two to four participants per event, which is dependent on the driver's endurance abilities, length of the race, or even the rules for each event.
