In the world of cinema, Secretariat, featured in the movie of the same name, holds the title of the fastest horse. The real-life Secretariat was an American Thoroughbred racehorse who, in 1973, became the first Triple Crown winner in 25 years. His records in the Kentucky Derby and the Belmont Stakes still stand today. In the Belmont Stakes, he ran the 1.5 miles in a breathtaking 2 minutes and 24 seconds, finishing an astonishing 31 lengths ahead of the second-place horse.
