Like the Kentucky Derby, the Longines Kentucky Oaks race is one of the longest continually held sporting events in American history, and one of the only horse races to take place at the original site of its inception. The race was established on May 19th, 1875, by the same founder of the Kentucky Derby, Colonel Meriwether Lewis Clark, and is modeled after the British Epsom Oaks.

Kentucky Oaks Day at Churchill Downs is the second highest attended horse race in the United States – following the Triple Crown of racing; the Kentucky Derby, the Preakness Stakes, and the Belmont Stakes. Aside from thunderous live horse racing, fans celebrate fashion and fundraising for critical women’s health issues.
