24 Hours of Le Mans - The Circuit

The Circuit

The circuit on which the 24 Hours of Le Mans is run is named the Circuit de la Sarthe (Circuit of the Sarthe), after the department that Le Mans is within. It consists of both permanent track and public roads that are temporarily closed for the race. Since 1923, the track has been extensively modified, mostly for safety reasons, and currently is 13.629 km in length. Although it initially entered the town of Le Mans, the track was cut short in order to better protect spectators. This led to the creation of the Dunlop Curve and Tertre Rouge corners before rejoining the old circuit on the Mulsanne. Another major change was on the Mulsanne itself, when the FIA decreed that it would no longer sanction any circuit that had a straight longer than 2 km. This led to the addition of two chicanes, reducing the time that the cars spent travelling at very high speeds on the old 6 km long straight.

The public sections of the track differ from the permanent circuit, especially in comparison with the Bugatti Circuit which is inside the Circuit de la Sarthe. Due to heavy traffic in the area, the public roads are not as smooth or well kept. They also offer less grip because of the lack of soft tyre rubber laid down from racing cars, though this only affects the first few laps of the race. The roads are closed only within a few hours of the practice sessions and the race, before being opened again almost as soon as the race is finished. Workers have to assemble and dismantle safety barriers every year for the public sections.
