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.
In 1890 Morris Park Racecourse in the Bronx, New York hosted the Preakness Stakes. This race was run under handicap conditions, and the age restriction was lifted. The race was won by a five-year-old horse named Montague. After 1890, there was no race run for three years.
