Secretariat was an American thoroughbred that won the Triple Crown in 1973, the first to achieve that level in 25 years. He set records in both the Kentucky Derby and the Belmont Stakes, winning the latter by 31 lengths. Secretariat was named Horse of the Year in both 1972 and 1973. Following retirement from racing, he sired as many as 600 foals. He died in October 1989 at the age of 19.
