how many miles is the le mans track
24 Hours of Le Mans The circuit on which the 24 Hours of Le Mans is run is named the Circuit de la 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 now is 13.626 km (8.467 mi) 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 in 1990, when the FIA decreed that it would no longer sanction any circuit that had a straight longer than 2 km (1.2 mi). To comply with this, two chicanes were added to the 6 km long straight. The addition of the chicanes was further influenced by the fact that the speed of WM P88-Peugeot French driver Roger Dorchy had been timed at 405 km/h (252 mph) during the 1988 race.
