Meriwether Lewis Clark, Jr., who built Churchill Downs in Louisville, wanted his track to have a race that would rival England’s Epsom Derby. After visiting England to study both its tracks and its races, he established the Kentucky Derby, which was first run on May 17, 1875. Except for 1879 through 1895, when it was 1 & 1/2 miles, the Derby has always been run at 1 & 1/4 miles.
