The Circuit de la Sarthe is thirteen kilometres long and most of it is public road, closed for the week. Cars run flat out for twenty-four hours, through the night and the dawn, down the Mulsanne straight and past a fairground that operates the whole time. The race rewards reliability over speed, which is why manufacturers have used it as an engineering proving ground since 1923 — disc brakes, fuel injection and hybrid drivetrains all did their public apprenticeship here.
The Automobile Club de l'Ouest reported 350,105 spectators across the 2026 race week, a counted ticketed figure covering practice, qualifying and the race itself.
The crowd is a substantial part of the event. The infield campsites are occupied for days, largely by British, Dutch, German and Belgian visitors who drive down, which makes Le Mans one of the more genuinely international audiences in the French calendar even though no formal origin survey is published.
Campsite and grandstand bookings open the previous autumn and the good ones go immediately. A general admission ticket allows walking most of the circuit, which is the best way to see it.
PlanningSeasonal window in mid-June, fixed a year ahead; campsite bookings open the previous autumn.

Measured share
Not measured on the perimeter of the attendance figure. 431,967 unique visitors in 2023 is neither the 325,000 official count of that edition — the publisher attributes the gap to under-16s and accredited staff — nor the 350,105 spectators of 2026 carried above. Multiplying the share by the attendance figure produces a quantity nobody measured.
