September 15th, 1973, Secretariat ran a race at Belmont against a horse that had just recently beat him, Onion, and previous Kentucky Derby Winner, Riva Ridge. In the end, Secretariat proved to be the great that he was and won by 3.5 lengths. Also true to fashion, Big Red set a record while schooling the horses too. He ran a mile and an eighth in 1.45. Simply amazing.
Congrats again Secretariat! I'm glad I could share this happy date with you!
