in 1973 blowing field away by 33 lengths!! best horse ever! man of war was good too in daay!

Answer 1

This sounds sappy I know, but Seabiscuit.  He raced more, over a longer career than most horses, even overcoming major injuries.  Nevermind that most people thought he wasn't much of a racehorse with his bad legs, but he took the nation by storm, and reintroduced a wary public to the joys of horse racing.  For that alone he is the best, but to accomplish all that on top of the everyday obstacle of a body not designed to be a perfect runner.......wow.
