The Preakness Stakes is an American flat thoroughbred horse race held on the third Saturday in May each year at Pimlico Race Course in Baltimore, Maryland. It is a Grade I race run over a distance of 9.5 furlongs (13â16 miles (1,900 m)) on dirt.
It is the second jewel of the Triple Crown, held two weeks after the Kentucky Derby and three weeks before the Belmont Stakes. First run in 1873, the Preakness Stakes was named by a former Maryland governor after a winning colt at Pimlico. The race has been termed The Run for the Black-Eyed Susans because a blanket of yellow flowers altered to resemble Maryland's state flower is placed around the winner's neck.
