Secretariat (March 30, 1970 – October 4, 1989) was an American Thoroughbred racehorse considered by many to be the greatest racehorse of all time: Secretariat not only won the 1973 Triple Crown but set still standing track records in two of the three races in the Series, the Kentucky Derby and the Belmont Stakes. Secretariat was affectionately nicknamed "Big Red" by his owner because of his size and brilliant chestnut color, or, perhaps, in an attempt to draw comparisons to the great Man O'War (who never raced in the Kentucky Derby).
