The 1957 24 Hours of Le Mans was the 25th running of the 24 Hours of Le Mans, Grand Prix of Endurance, and took place on 22 and 23 June 1957, on the Circuit de la Sarthe. It was also the fifth round of the F.I.A. World Sports Car Championship. Some 250,000 spectators had gathered for Europe’s classic sports car race, around an 8.38-mile course. The prospect of an exciting duel between Ferrari, Maserati, Jaguar, Aston Martin and Porsche was enough to draw large crowds to the 24 Hours race, now back at its usual date and reintegrated into the World Championship.
