Check out my page about Triple Crown Winners.
In all of horse racing, only three races matter:
Kentucky Derby, Preakness and Belmont. They make up racing's
Triple Crown. Eleven thoroughbred horses have won the Triple Crown. Those horses are Sir Barton 1919, Gallant Fox 1930, Omaha 1935, War Admiral 1937, Whirlaway 1941, Count Fleet 1943, Assault 1946, Citation 1948, Secretariat 1973, Seattle Slew 1977 and Affirmed 1978. There were three Triple Crown Winners in the 1930s, four in the 1940s and three in the 1970s. A horse is a horse. Even though I have their pictures on my site, I could put any name on any horse and would not know the difference. All thoroughbreds descended from three Arab stallions brought to England over 300 years ago. Thoroughbreds can run 40 miles an hour.....
