Preakness Stakes is an American (United States) Grade I stakes race (Graded stakes race) 1-3/16 mile (1.91 km) thoroughbred horse race for three-year-old horses, held on the third Saturday in May each year at Pimlico Race Course in Baltimore, Maryland. Colts (Colt (horseracing)) and geldings carry 126 pounds (57 kg); fillies (filly (horseracing)) 121 lb (55 kg). The Preakness Stakes has been termed "The Run for the Black-Eyed Susans" because a blanket of Black-eyed Susans (Rudbeckia hirta, the state flower of Maryland) is traditionally placed around the winners neck. The attendance at the Preakness Stakes ranks second in North America and usually surpasses the attendance of all other stakes races including the Belmont Stakes, the Breeders Cup and the Kentucky Oaks. The attendance of the Preakness Stakes typically only trails the Kentucky Derby, for more information see American Thoroughbred Racing top Attended Events.
