In February 1969, Diane Crump, a 20-year-old jockey, saddled up at Hialeah Park Race Track as the first woman to ride a parimutuel race in the United States. (Parimutuel is a system of betting.) She finished in 10th place out of 12 horses on a 48-1 shot, Bridle 'n Bit, in the seventh race.
This accomplishment sent her across the country, and to Puerto Rico and Venezuela, as a female jockey.
In 1970, with some 40 wins under her belt, Crump made history riding Fathom, a horse she trained with her husband, in the world-famous Kentucky Derby.
