Though Alydar is nearly always mentioned in conjunction with his great rival, he was a tremendous racehorse in his own right. He faced Affirmed 10 times, and while he was victorious in only three of those meetings, he was such a determined runner that he is as much beloved by racing fans as if he had won them. And for all that, his racing resume is hardly shabby---it includes wins in the Champagne, the Great American, the Tremont, the Flamingo, the Florida Derby, the Bluegrass, the Travers, and the Whitney.
Alydar also proved to be an outstanding horse in the breeding shed, siring superstar Easy Goer; Kentucky Derby, Preakness, and Breeders Cup Classic winner Alysheba; Kentucky Derby winner Strike the Gold; Travers winner Turkoman; Horse of the Year Criminal Type; and champion filly Althea to name just a few.
