The Kentucky Derby, the longest-running continuous sporting event in the United States, has been a major part of the event's spectacle since its inception in 1875. The race has produced legendary horses like Secretariat and trainers like Bob Baffert and Ben Jones. The Derby attracts high-profile guests such as celebrities, royalty, and U.S. presidents. Matt Winn, former vice president and general manager of Churchill Downs, is credited with popularizing the Kentucky Derby in the early 20th century, shipping his highly regarded filly, Regret, from New Jersey to compete in the race. The event has also produced several notable trainers, owners, and jockeys.
