Secretariat, the Triple Crown winner in 1973, has a long-lasting legacy in horse racing for more reasons than one. In the 1973 Kentucky Derby, Secretariat set the fastest Derby time ever posted, getting through the one-and-a-quarter mile track in 1:59.40. Over 50 years later, that record still stands, and the legendary racehorse nicknamed "Big Red" is, incredibly, an ancestor of each horse competing in the 2025 Kentucky Derby.
Yes, really.
