Created in 1923, the 24 Hours of Le Mans is the oldest and one of the most prestigious car races in the world. A stern test of the reliability of the machines as well as the physical and mental stamina of the drivers, Le Mans attracts some of the greatest names in motor sport. On the 13.6-kilometre (8.4 miles) Circuit de la Sarthe in north-west France, some 62 cars, each with teams of three drivers, race against each other, divided into two Prototype and one GT Class. The winning team is the one which covers the greatest distance in 24 hours, some 5,300 kilometres (3,293 miles). Rolex has been the Official Timepiece of the race since 2001.
