The $2 million Kentucky Derby takes place on the first Saturday in May at historic Churchill Downs in Louisville, Ky. Inaugurated in 1875, the legendary 1 ¼-mile race for 3-year-olds is the oldest continuously held major sporting event in North America and the first leg of horse racing's challenging Triple Crown series. Also known as the "The Run for the Roses" and "The Most Exciting Two Minutes in Sports," the Kentucky Derby is the most attended horserace in the nation, with more than 170,000 attendees in 2015.
