The 24 Hours of Le Mans (French: 24 Heures du Mans) is the world's oldest active sports car race in endurance racing, held annually since 1923 near the town of Le Mans, France. Commonly known as the Grand Prix of Endurance and Efficiency, race teams have to balance speed against the cars' ability to run for 24 hours without sustaining mechanical damage to the car and manage the cars' consumables, primarily fuel, tyres and braking materials. The endurance of the drivers is likewise tested as drivers frequently spend stints of over two hours behind the wheel before stopping in the pits and allowing a relief driver to take over the driving duties. Drivers then grab what food and rest they can before returning to drive another stint. Today it is mandated that three drivers share each competing vehicle.

The race is organised by the Automobile Club de l'Ouest (ACO) and runs on the Circuit de la Sarthe, a circuit containing a mix of closed public roads and specialist motor racing circuit that are meant not only to test a car and driver's ability to be quick, but also to last over a 24 hour period. The competing teams will race in groups called classes for cars of similar specification while at the same time competing for outright placing amongst all of the classes. Originally the race was held for cars as they were sold to the general public which were then called Sports Cars compared to the specialist racing cars used in Grands Prix. Over time the competing vehicles evolved away from their publicly-available road car roots and today the race is made of two classes specialised enclosed-bodywork two-seat Prototype sports cars and two classes of Grand Touring cars which bear much closer resemblance to high performance sports cars as sold to the public.

Le Mans (French pronunciation: [ləmɑ̃]) is a city in France, located on the Sarthe River. Traditionally the capital of the province of Maine, it is now the capital of the Sarthe department and the seat of the Roman Catholic diocese of Le Mans. Le Mans is a part of the Pays de la Loire region.

Its inhabitants are called Manceaux and Mancelles. It has been host to the famous 24 Hours of Le Mans sports car race since 1923.

First mentioned by Ptolemy, the Roman city Vindinium was the capital of the Aulerci, a sub tribe of the Aedui. Le Mans is also known as Civitas Cenomanorum (City of the Cenomani). Their city, seized by the Romans in 47 BC, lies in the ancient Roman province of Gallia Lugdunensis. An amphitheatre built in the third century AD is still visible, but the thermae were demolished during the crisis of the third century to build the city's walls, which remain some of the most complete circuit of Gallo-Roman city walling that survives.
