2011 Prix de l'Arc de Triomphe
The 2011 Prix de l'Arc de Triomphe was a horse race held at Longchamp on Sunday 2 October 2011. It was the 90th running of the Prix de l'Arc de Triomphe.
The winner was Danedream, a three-year-old filly trained in Germany by Peter Schiergen. The winning jockey was Andrasch Starke.
Danedream was the second German-trained horse to win the "Arc". The only prior victory was that of Star Appeal in 1975.
The winning time of 2m 24.49s set a new record for the event. The previous record of 2m 24.60s was achieved by Peintre Celebre in 1997.
Unusually for the race, the first three finishers were all fillies.
