The Tampa Bay Derby is an American Thoroughbred horse race held in mid-March at Tampa Bay Downs. A Grade II event since 2011, it is open to three-year-olds at a distance of one and one-sixteenth miles (8½ furlongs) on the dirt. The race has gained in popularity over the past few years and is now listed as an official prep race for the Kentucky Derby. In 2007, Street Sense became the first Tampa Bay Derby participant to win the Kentucky Derby.
