Ksar was the first dual winner of the Arc (there have been six in all) in 1921 and 1922.

The early 1930s saw Motrico become the second dual winner of the Arc. The Maurice d’Okhuysen-trained horse gained his first success as a five-year-old in 1930, bypassed the following year’s running taken by Pearl Cap, and then secured his second victory in 1932.

Bred and owned by Marcel Boussac, Corrida, successful in back-to-back Arcs in 1936 and 1937, was one of the best fillies to race in Europe between the World Wars.

Former cavalry officer Francois Mathet sent out Tantieme to win both the 1950 and 1951 renewals. The horse’s initial success came as a three-year-old, with the first six places being filled by members of the Classic generation. Tantieme justified favouritism the following year and beat Nuccio, who was then successful 12 months later, by two lengths.

Ribot became the second of the three post-war dual Arc winners in 1955 and 1956. One of the greatest horses of all time, the Italian-trained colt won his two Arcs by a combined distance of nine lengths.

The trainer-jockey combination of Vincent O’Brien/Lester Piggott was an awesome team at its peak and the pair assisted the Robert Sangster-owned Alleged in becoming the most recent dual Arc winner in 1977 and 1978.
