The Kentucky Derby is a horse race held annually in Louisville, Kentucky, United States, almost always on the first Saturday in May, capping the two-week-long Kentucky Derby Festival. The competition is a Grade I stakes race for three-year-old Thoroughbreds at a distance of one and a quarter miles (2.0 km) at Churchill Downs. Colts and geldings carry 126 pounds (57 kilograms) and fillies 121 pounds (55 kilograms).It is dubbed "The Run for the Roses", stemming from the blanket of roses draped over the winner. It is also known in the United States as "The Most Exciting Two Minutes in Sports" or "The Fastest Two Minutes in Sports" because of its approximate duration. It is the first leg of the American Triple Crown, followed by the Preakness Stakes, and then the Belmont Stakes. Of the three Triple Crown races, the Kentucky Derby has the distinction of having been run uninterrupted since its inaugural race in 1875. The race was rescheduled to September 2020 due to the COVID-19 pandemic. The Preakness and Belmont Stakes races had taken hiatuses in 1891–1893 and 1911–1912, respectively. Even with the Olympics and major professional sports leagues canceled at those points, the Derby, Preakness, and Belmont took place during the Great Depression and both World Wars.A horse must win all three races to win the Triple Crown. In the 2015 listing of the International Federation of Horseracing Authorities (IFHA), the Kentucky Derby tied with the Whitney Handicap as the top Grade 1 race in the United States outside the Breeders' Cup races.The attendance at the Kentucky Derby ranks first in North America and usually surpasses the attendance numbers of all other stakes races including the Preakness Stakes, Belmont Stakes, and the Breeders' Cup.
