The Preakness Stakes is an American flat thoroughbred horse race held on the third Saturday in May every year at Pimlico Race Course in Baltimore, Maryland. It is a Grade I race kept running over a separation of 9.5 furlongs (1 3⁄16 miles (1,900 m)) on dirt. Colts and geldings carry 126 pounds (57 kg); fillies 121 lb (55 kg). It is the second gem of the Triple Crown, held two weeks after the Kentucky Derby and three weeks before the Belmont Stakes. First keep running in 1873, the Preakness Stakes was named by a previous Maryland senator after a triumphant foal at Pimlico. The race has been named "The Run for the Black-Eyed Susans" in light of the fact that a blanket of yellow blooms modified to resemble Maryland's state flower is put over the shrinks of the triumphant foal or filly.
