LOUISVILLE, Ky. – You can find three “Ls” in this river city’s name, two more in the name of the city’s storied racetrack, but the world’s most famous horse race at Churchill Downs here in Louisville, will not include a single “L” next to the names of horses racing in the 2021 Kentucky Derby.
“L” in past performance notation stands for “Lasix,” and the masters of the Derby, like much of North American racing, have taken a stand against a race-day medication that, until 2020, had become ubiquitous in the American Thoroughbred.
