In 1973, Secretariat, the greatest champion in horse-racing history, won the Triple Crown. The only horse to ever grace the covers of Time, Newsweek, and Sports Illustrated in the same week, he also still holds the record for the fastest times in both the Kentucky Derby and the Belmont Stakes. He was also the only non-human chosen as one of ESPN's "50 Greatest Athletes of the Century". The tale of "Big Red" is an enduring and inspiring classic, more than 30 years after its initial publication.
