The Mac Diarmida Stakes is a Grade II American Thoroughbred horse race for horses four-years-old and older run over a distance of one-and-three-eighth miles (11 furlongs) on the turf, annually in late February or early March at Gulfstream Park in Hallandale Beach, Florida.
[1] The event was inaugurated on 16 January 1995 for three-year-olds at a distance of 1 mile and 70 yards and was held on the dirt track.
[2] The race was named in honor of Florida-bred Mac Diarmida who was the American Champion Male Turf Horse of 1978.
[4] In 1997, wet weather forced the race to be moved from the turf course to the main dirt track and set at a distance of one-and-one-quarter miles with conditions changed to allow horses four years old and older.
