Saturday 26th May 1923
The first 24 Hours of Le Mans, organised by the Automobile Club de L’Ouest, began. The race traditionally starts at 4 p.m. on the Saturday and uses mostly normal country roads. Over the years, several purpose-built sections replaced some of the normal roads previously used, including the Porsche Curves, which bypass the former dangerous Maison Blanche section between buildings. The permanent Bugatti Track surrounds the facilities at the start/finish. That first Le Mans was won by French drivers André Lagache and René Léonard in a Chenard et Walcker. British driver Frank Clement and Canadian John Duff finished fourth in a 3-litre Bentley.
