Prix Bertrand du Breuil Prix de Diane. In 2013 the race was renamed in memory of Bertrand du Breuil (1926-2011), the last president of the Societe d'Encouragemment, forerunner of France Galop. Prix Bertrand du Breuil The Prix Bertrand du Breuil is a Group 3 flat horse race in France open to thoroughbreds aged four years or older. It is run at Chantilly over a distance of 1,600 metres (about 1 mile), and it is scheduled to take place each year in June. The earliest version of the event was established at Chantilly in 1852. Its prize money was originally provided by the Chemin de
Ellis Park Race Course purses for a five-day race meeting. On November 10, 1922 a 10-day thoroughbred meet with purses of $62,000 was held. The meet was a stop on the train route south to New Orleans for winter racing at Fair Grounds Race Course. These short meets didn't meet the needs of the track and in 1925, after three years of operation, the Green River Jockey Club went bankrupt. In 1925 James C. Ellis, a Rockport businessman, purchased the track, then called Dade Park. He brought about many changes at the track including adding a tote board wagering system and a terrace grandstand.
