The Kentucky Derby was first held in 1875 and ranks as the longest continuously held major sporting event in the United States.
This year will mark the 148th edition of the Kentucky Derby Presented by Woodford Reserve, which had been held on the first Saturday in May at Churchill Downs every year since 1946 before the COVID-19 pandemic forced the postponement of the race in 2020 until Sept. 5.
In 2021, the Kentucky Derby returned to its normal place on the calendar as the first jewel of the Triple Crown (after following the Belmont Stakes in 2020) and things seemed to return to normal … until a few days after the race when it was discovered that Medina Spirit had tested positive for a banned substance. He subsequently was disqualified and Mandaloun was elevated to first. The 2021 Kentucky Derby marked the second time in three years that the 3-year-old who crossed the finish line first in the Kentucky Derby was not the official winner after Maximum Security was disqualified for interference in 2019 and Country House elevated to first.
With so much history surrounding the first jewel of the Triple Crown, there are many interesting facts about the race since Aristides won the inaugural edition in the 19th Century. Let’s explore:
1) The most common color of Kentucky Derby winners is bay with 56, inclduing Mandaloun in 2021, followed by chestnut with 48 winners and brown with 17. Eight Kentucky Derby winners were gray or roan, most recently Giacomo in 2005.
