A short history
With a fifth of France's racehorses trained in town, Chantilly is this nation's capital of the horse. In the shadow of its château, the Prix de Diane and Prix du Jockey Club (the French Derby, held a couple of weeks earlier) are the racecourse highlights. For three-year-old fillies, the Prix de Diane has served as the French Oaks since 1843, seeing six horses graduate to success in the country's premier race at Lonchamp: the Prix de l'Arc de Triomphe. With thousands packed into the stands and course centre, this is one of the country's biggest sporting days out.
What happened in 2023's edition?
The 2023 Prix de Diane Longines was a third Group One success for Christopher Head's Blue Rose Cen, who had Aurélien Lemaître onboard. Blue Rose Cen continued her journey through France's Triple Crown for fillies, after taking the Prix d'Essai des Pouliches at Lonchamp last month. She took this race by four lengths. British hope Running Lion, who had Oisin Murphy aboard, and is trained by John & Thady Gosden, came home a disappointing last.
