Seabiscuit was a champion thoroughbred race horse in the United States. From an inauspicious start, Seabiscuit became an unlikely champion and a symbol of hope to many Americans during the Great Depression. In one of his most famous races, November 1, 1938, Seabiscuit met War Admiral in what was dubbed the "Match of the Century" and was one of the most anticipated sporting events in U.S. history.

As a result of his races that year and the victory over War Admiral, Seabiscuit was named "Horse of the Year" for 1938. On April 10, Seabiscuit's retirement from racing was officially announced. When he was retired to the Ridgewood Ranch near Willits, California, Seabiscuit, the horse nobody wanted, was horse racing's all-time leading money winner. Put out to stud, Seabiscuit sired 108 foals, including two moderately successful racehorses, Sea Swallow and Sea Sovereign.
