Every first Sunday in June, the Prix du Jockey Club, a galloping horse race on a flat grassy track, is held at the Chantilly racecourse. With a total allocation of €1,500,000, this flat race is the best endowed in France behind the Prix de l'Arc de Triomphe, with its €5,000,000. This Prize is the French counterpart of the Epsom Derby and Irish Derby. Placed under the sponsorship of the mythical Jockey Club and also sponsored by the QIPCO as the Prix de l'Arc de Triomphe, this race is classified as a Group I event.
Until 1946, during the Prix du Jockey Club, only horses born and bred in France were allowed to participate. The race is now open to whole foals and 3 year old fillies from all over the world.
On the grass track of the Chantilly racecourse, the prize puts 3-year-old thoroughbred foals and fillies in competition. Since 2005, the race has been run on a 2,100-meter long course. On the last straight line, there is a 600-meter climb. The greatest gallopers from all over the world meet on the racecourse track located at the foot of the Château de Chantilly, and compete for a total allocation of €1,500,000, the second best endowed French flat race.
