What is the name of the horse who was Seabiscuit's real competitor?

Answer 1

Seabiscuit had an extraordinarily long career for a racehorse. From his 2 year old year until his retirement at age 7. Most Thoroughbred's racing careers last 2 or 3 years on average. He raced against many horses in those 7 years but his most memorable would have been the match race between him and superhorse champion War Admiral. The Biscuit was the extreme underdog in this historic race held in the fall of 1938. But true to form, the little bay from California humiliated the Admiral, making him eat dirt in the home stretch, crossing the finish line 4 full lengths ahead of his competitor.

Answer 2

Seabiscuit's main challenger in any form, was of course, War Admiral.
