The 24 Hours Le Mans race is held in June, leading at times to very hot conditions for drivers, particularly in closed vehicles with poor ventilation. The race begins in mid-afternoon and finishes the following day at the same hour the race started the previous day. Over the 24 hours, modern competitors often cover distances well over 5,000 km (3,110 mi). The record was set in 2010 when 5,410 km (3,360 mi) was covered during the race. It is six times the length of the Indianapolis 500, or approximately 18 times longer than a Formula One Grand Prix.

The race is the world's oldest active sports car race in endurance racing, held annually since 1923 near the town of Le Mans, France. It is one of the most prestigious automobile races in the world and is often called the "Grand Prix of Endurance and Efficiency". The event represents one leg of the Triple Crown of Motorsport; other events being the Indianapolis 500, and the Monaco Grand Prix.

The race is organized by the Automobile Club de l'Ouest (ACO) and runs on the Circuit de la Sarthe, which contains a mix of closed public roads and a specialist racing circuit, in which racing teams have to balance speed with the cars' ability to race for 24 hours without sustaining mechanical damage.
