[5] With the help of the larger Automobile Club de France they organised a race on local public roads, on a 65-mile triangular course connecting Le Mans with Saint-Calais and La Ferté-Bernard.
After World War I, the ACO turned its attention to designing a shorter circuit on public roads to the south of the city.
The organisation's chief secretary Georges Durand, together with magazine editor Charles Faroux of La Vie Automobile and tyre manufacturer Emile Coquille, came up with the idea for a 24-hour race.
The ACO set about the task of reconstruction, aided by Government Minister and Sarthe députée Christian Pineau who provided the first millions.
It led to many actions by the ACO to subsequently change buildings and the procedures used at the circuit, as well as to redesign the pit lane and front stretch where the accident occurred.
It also led to a change of ACO rules for the type of cars permitted in the 24 Hours of Le Mans for the following years, as well as applying a fuel-consumption formula.
