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.
The Preakness Stakes takes place precisely 2 weeks after the Kentucky Derby. Did you know it is easy to remember the dates, too. The Kentucky Derby is always the first Saturday in May. (Think First Friday's but make it First Saturday's). The Preakness follows 2 weeks later.
