The Kentucky Derby // is a horse race held annually in Louisville, Kentucky, United States, almost always on the first Saturday in May, capping the two-week-long Kentucky Derby Festival. The competition is a Grade I stakes race for three-year-old Thoroughbreds at a distance of one and a quarter miles (2.0 km) at Churchill Downs. Colts and geldings carry 126 pounds (57 kilograms) and fillies 121 pounds (55 kilograms).
It is dubbed "The Run for the Roses", stemming from the blanket of roses draped over the winner. It is also known in the United States as "The Most Exciting Two Minutes in Sports" or "The Fastest Two Minutes in Sports" because of its approximate duration. It is the first leg of the American Triple Crown, followed by the Preakness Stakes, and then the Belmont Stakes. Of the three Triple Crown races, the Kentucky Derby has the distinction of having been run uninterrupted since it's inaugural race in 1875. The race was rescheduled to September, 2020 due to the COVID-19 pandemic. The Preakness and Belmont Stakes races had taken hiatuses in 1891–1893 and 1911–1912, respectively. Even with the Olympics and major professional sports leagues canceled at those points, the Derby, Preakness, and Belmont took place during the Great Depression and both World Wars.
A horse must win all three races to win the Triple Crown. In the 2015 listing of the International Federation of Horseracing Authorities (IFHA), the Kentucky Derby tied with the Whitney Handicap as the top Grade 1 race in the United States outside the Breeders' Cup races.
The attendance at the Kentucky Derby ranks first in North America and usually surpasses the attendance numbers of all other stakes races including the Preakness Stakes, Belmont Stakes, and the Breeders' Cup.

In 1872, Col. Meriwether Lewis Clark Jr., grandson of William Clark of the Lewis and Clark expedition, traveled to England, visiting Epsom in Surrey where The Derby had been running annually since 1780. From there, Clark went on to Paris, France, where a group of racing enthusiasts had formed the French Jockey Club in 1863. They had organized the Grand Prix de Paris at Longchamp, which at the time was the greatest race in France.
Returning home to Kentucky, Clark organized the Louisville Jockey Club to raise money for building quality racing facilities just outside the city. The track would soon become known as Churchill Downs, named for John and Henry Churchill, who provided the land for the racetrack. The naming went official in 1937.
The Kentucky Derby was first run at 1+1⁄2 miles (12 furlongs; 2.4 km) the same distance as the Epsom Derby, before changing lengths in 1896 to its current 1+1⁄4 miles (10 furlongs; 2 km). On May 17, 1875, in front of an estimated crowd of 10,000 people, a field of 15 three-year-old horses contested the first Derby. Under jockey Oliver Lewis, a colt named Aristides, who was trained by future Hall of Famer Ansel Williamson, won the inaugural Derby. Later that year, Lewis rode Aristides to a second-place finish in the Belmont Stakes.
Although the first race meeting proved a success, the track ran into financial difficulties, and in 1894 the New Louisville Jockey Club was incorporated with the new capitalization and improved facilities. Despite this, the business floundered until 1902 when Col. Matt Winn of Louisville put together a syndicate of businessmen to acquire the facility. Under Winn, Churchill Downs prospered, and the Kentucky Derby then became the preeminent stakes race for three-year-old thoroughbred horses in North America.
Thoroughbred owners began sending their successful Derby horses to compete in two other races. These two are the Preakness Stakes at the Pimlico Race Course, in Baltimore, and the Belmont Stakes in Elmont, New York. The three races offered large purses, and in 1919 Sir Barton became the first horse to win all three races. However, the term Triple Crown didn't come into use for another eleven years. In 1930, when Gallant Fox became the second horse to win all three races, sportswriter Charles Hatton brought the phrase into American usage. Fueled by the media, public interest in the possibility of a "superhorse" that could win the Triple Crown began in the weeks leading up to the Derby. Two years after the term went in use, the race (until that time ran in mid-May since inception) changed the date to the first Saturday in May. This change allows for a specific schedule for the Triple Crown races. Since 1931, the order of Triple Crown races has been the Kentucky Derby first, followed by the Preakness Stakes and then the Belmont Stakes. Before 1931, eleven times the Preakness was run before the Derby. On May 12, 1917, and again on May 13, 1922, the Preakness and the Derby took place on the same day. On eleven occasions the Belmont Stakes was run before the Preakness Stakes, and in 2020, the Belmont was run first, then the Kentucky Derby, and the Preakness Stakes last.
On May 16, 1925, the first live radio broadcast of the Kentucky Derby aired on WHAS as well as on WGN in Chicago. On May 7, 1949, the first television coverage of the Kentucky Derby took place, produced by WAVE-TV, the NBC affiliate in Louisville. This coverage was aired live in the Louisville market and sent to NBC as a kinescope newsreel recording for national broadcast. On May 3, 1952, the first national television coverage of the Kentucky Derby took place, aired from then-CBS affiliate WHAS-TV. In 1954, the purse exceeded US$100,000 for the first time. In 1968, Dancer's Image became the first horse to win the race and then faced disqualification. A urine test revealed traces of phenylbutazone (an anti-inflammatory painkiller drug) inside Dancer's Image. Forward Pass won after a protracted legal battle by the owners of Dancer's Image (which they lost). Forward Pass thus became the eighth winner for Calumet Farm. Unexpectedly, the regulations at Kentucky thoroughbred race tracks were changed some years later, allowing horses to run on phenylbutazone. In 1970, Diane Crump became the first female jockey to ride in the Derby, finishing 15th aboard Fathom.
The fastest time ever run in the Derby was in 1973 at 1:59.4 minutes, when Secretariat broke the record set by Northern Dancer in 1964 – a record time yet to be topped. Also during that race, he did something unique in Triple Crown races: for each successive quarter ran, his times were faster. Although the races do not record times for non-winners, in 1973 Sham finished second, two and a half lengths behind Secretariat in the same race. Using the thoroughbred racing convention of one length equaling one-fifth of a second to calculate Sham's time, he also finished in under two minutes. Another sub-two-minute finish, only the third, was set in 2001 by Monarchos at 1:59.97, the first year the race used hundredths of seconds instead of fifths in timing.
The Kentucky Derby began offering $3 million in purse money in 2019. Churchill Downs officials have cited the success of historical race wagering terminals at their Derby City Gaming facility in Louisville as a factor behind the purse increase. The Derby first offered a $1 million purse in 1996; then doubled to $2 million in 2005.
In 2020, The Kentucky Derby was postponed from May 2 to September 5 due to the COVID-19 pandemic. This was the second time in history the race had been postponed, the other being in 1945. Churchill Downs used a new singular 20-stall starting gate for the 2020 Kentucky Derby, replacing the previous arrangement that used a standard 14-stall gate and an auxiliary six-stall gate. The old setup contributed to congestion at the start of the race, especially in the gap between the two gates.
The Kentucky Derby is the oldest continuously held major sporting event in the United States (1875).
Millions of people from around the world bet at various live tracks and online sportsbooks. In 2017, a crowd of 158,070 watched Always Dreaming win the Derby, making it the seventh biggest attendance in the history of the racetrack. The track reported a wagering total of $209.2 million from all the sources on all the races on the Kentucky Derby Day program. It was a 9 percent increase compared to the total of $192.6 million in 2016 and an increase of 8 percent over the previous record set in 2015 of $194.3 million. TwinSpires, a platform for betting online and a partner of the Kentucky Derby and the Breeders' Cup, recorded $32.8 million in handle on the Churchill Down races for the Kentucky Derby Day program. This record was a 22 percent increase over the preceding year. On the Kentucky Derby race alone, the handle of TwinSpires was $20.1 million, which is a 22 percent rise compared to the prior year.
Norman Adams has been the designer of the Kentucky Derby Logo since 2002. On February 1, 2006, the Louisville-based fast-food company Yum! Brands, Inc. announced a corporate sponsorship deal to call the race "The Kentucky Derby presented by Yum! Brands." In 2018 Woodford Reserve replaced Yum! Brands as the presenting sponsor.
In addition to the race itself, several traditions play a significant role in the Derby atmosphere. The mint julep—an iced drink consisting of bourbon, mint, and sugar syrup—is the traditional beverage of the race. The historic beverage comes served in an ice-frosted silver julep cup. However, most Churchill Downs patrons sip theirs from souvenir glasses (first offered in 1939 and available in revised form each year since) printed with all previous Derby winners. Also, burgoo, a thick stew of beef, chicken, pork, and vegetables, is a popular Kentucky dish served at the Derby.
The infield—a spectator area inside the track—offers general admission prices but little chance of seeing much of the race, particularly before the jumbotron installation in 2014. Instead, revelers show up in the infield to party with abandon. By contrast, "Millionaire's Row" refers to the expensive box seats that attract the rich, the famous and the well-connected. Women appear in elegant outfits lavishly accessorized with large, elaborate hats. Following the Call to the Post, as the horses start to parade before the grandstands, the University of Louisville Cardinal Marching Band plays Stephen Foster's "My Old Kentucky Home". This song is a tradition which began in 1921. The event attracts spectators from a large area, flying in hundreds of private aircraft to Louisville International Airport.
The Derby is frequently referred to as "The Run for the Roses", because a lush blanket of 554 red roses is awarded to the Kentucky Derby winner each year. The tradition originated in 1883 when New York City socialite E. Berry Wall presented roses to ladies at a post-Derby party. Churchill Downs founder and president, Col. M. Lewis Clark, attended that event. This gesture is believed to have led Clark to the idea of making the rose the race's official flower. However, it was not until 1896 that any recorded account referred to draping roses on the Derby winner. The Governor of Kentucky awards the garland and the Kentucky Derby Trophy. Pop vocalist Dan Fogelberg composed the song "Run for the Roses", released in time for the 1980 running of the race.
"Riders Up!" is the traditional command from the Paddock Judge for jockeys to mount their horses in advance of the upcoming race. Since 2012, a dignitary or celebrity attendee recites this phrase.
In the weeks preceding the race, numerous activities took place for the Kentucky Derby Festival. Thunder Over Louisville—an airshow and fireworks display—generally begins the festivities in earnest two weeks before the Derby.

- Maximum Security crossed the finish line first, but was disqualified for interference.
- Dancer's Image, ridden by Bobby Ussery, trained by Lou Cavalaris Jr., and owned by Peter D. Fuller, finished first, but was disqualified after a post-race urine sample revealed traces of a banned drug in the horse. The drug in question – phenylbutazone – is now legal for use on racehorses in many states, including Kentucky.
- Apollo (1882) was the only horse to have won the Derby without having raced at age two, until Justify in 2018.
- the Darley Arabian (1700c) sire line (all branched through the Eclipse (1764) line) produced 129 Derby winners (121 colts, 5 geldings, 3 fillies), including all winners from 1938 to present. The main branches of this sire line are:
- the King Fergus (1775) branch (all branched through the Voltigeur (1847) line), produced 14 winners, most recently, Go For Gin in 1994
- the Potoooooooo (1773) branch produced 115 winners (all branched through the Waxy (1790) line), including all winners from 1995 to present. The primary branch of this sire line is through Whalebone (1807), which has produced 110 winners. In turn, the primary branch continues through Sir Hercules (1826), which has produced 88 winners (including all winners since 2006), and then the Birdcatcher (1833) branch which produced 76 winners. From Birdcatcher, the branch of The Baron (1842) has produced 66 winners, of which 64 winners trace to Stockwell (1849). Stockwell's son Doncaster (1870) sired Bend Or (1877), whose sire line accounts for 62 winners. The main branch of the Bend Or sire line continued through his son Bona Vista with 53 winners, exclusively through the Phalaris (1913) line, which has dominated in the last several decades through the following sons:
- the Pharamond (1925) branch (4 winners all through the Tom Fool (1949) line, most recently Silver Charm in 1997);
- the Sickle (1924) branch (22 winners all branched through the Native Dancer (1950) line, nearly exclusively through Raise a Native, continued primarily through Mr Prospector with 14 winners);
- the Pharos (1920) branch (27 winners all branched through the Nearco (1935) line, through his sons Royal Charger (1942), Nearctic (1954), and Nasrullah (1940). The Nasrullah branch has produced 14 winners primarily due to his son Bold Ruler with 10 winners, while Nearctic produced 8 winners, exclusively through his son Northern Dancer with his win in the 1964 Kentucky Derby, and direct male progeny of 7 winners, including recent winners Justify (2018), Authentic (2020) and Medina Spirit (2021).
- Of special note, an offshoot of the Whalebone (1807) branch, the Camel (1822) branch, produced 2005 Kentucky Derby winner Giacomo. Since then, each winner of the Kentucky Derby has gone through Whalebone's more frequent sire line branch of Sir Herecules (1826).
