LOUISVILLE, Ky. — While 151 horses have crossed the finish line to win the Kentucky Derby, none captured hearts quite like Secretariat.

Affectionately known as “Big Red,” Secretariat not only dominated the sport but also became an emblem of American spirit, inspiring a Disney movie years after his illustrious career concluded.

His astounding Triple Crown victory was a feat not seen for a generation, renewing the nation’s infatuation with horse racing.

Prior to Secretariat’s triumph, the legendary Citation had been the last to achieve the Triple Crown, doing so in 1948. Between 1930 and 1948, seven horses claimed this honor, but it would not happen again for 25 years.

Chris Goodlett, senior director of curatorial and education at the Kentucky Derby Museum, emphasized the rarity of such an achievement, stating, “You’re reminded that winning those three races in a short time span is very difficult to do, and it takes a special horse in special circumstances to accomplish it.”

In 1973, that special horse was Secretariat.

“When we look back historically, we were in the midst of the Vietnam War at that time as well,” Goodlett said. “A lot of people paint Secretariat is kind of a hero that people could gather around.”

He galloped to victory at Churchill Downs in just under two minutes. Secretariat went on to win the Preakness, setting the stage for history.

Goodlett points out that he won the Belmont Stakes by 31 lengths, a jaw-dropping distance you can rewatch at the museum.

There is an exhibit dedicated to Secretariat on the second floor. There are replays of his victories, trophies and other items including a movie poster, bourbon bottle, and a customized U.K. basketball jersey.
