Two of France’s top thoroughbred horse races, the Prix du Jockey-Club and the Prix Diane, will be raced on the same card for the first time ever at the Chantilly racetrack on July 5, likely behind closed doors. Horseracing is a major economic activity in France with 10,000 licensed professionals, over 9,000 thoroughbred racehorses and 142 racetracks. Warm-up races to the Diane and the Jockey Club should be raced at Longchamp in Paris June 1, where France’s top race the Prix de L’Arc de Triomphe is raced in October.
