Circuit de la Sarthe is a semi-permanent motor racing circuit near Le Mans, France. It is most famous for hosting the annual 24 Hours of Le Mans endurance sports car race, one of the most prestigious automobile races in the world. The event tests the ability of manufacturers, teams, and drivers to produce cars that are fast, reliable, and efficient over a 24-hour period.

Circuit de la Sarthe is known for its mix of public roads and dedicated motor racing sections, which make up a long and challenging circuit with both high-speed straights and technical corners. One of the track's most notable features is the Mulsanne Straight (Ligne Droite des Hunaudières), a long straight where cars historically reached their top speeds before chicanes were added to improve safety.

The track layout has been modified several times throughout its history to enhance driver safety and to slow down vehicles due to the high-speed nature of the circuit. Despite these changes, it still remains one of the fastest and most demanding racing circuits in use today.

Furthermore, Circuit de la Sarthe boasts a combination of modern racing facilities and historic elements, embodying the rich history and evolution of motorsports. Its legacy continues to grow with each iteration of the 24 Hours of Le Mans and other racing events that take place on this iconic circuit.
