Derby History

Origins: The Louisville Gentleman and His Dream (1875)

The Kentucky Derby was the creation of Meriwether Lewis Clark Jr. — grandson of explorer William Clark of the Lewis and Clark Expedition. In 1872, Clark traveled to Europe and attended the Epsom Derby in England and the Grand Prix de Paris in France. He returned to Louisville inspired, determined to create an American equivalent that would put his city on the sporting world's map.

Clark organized the Louisville Jockey Club, leased land from his uncles (John and Henry Churchill, whose name would eventually adorn the track), and built a racecourse. On May 17, 1875, the first Kentucky Derby was run before an estimated crowd of 10,000 people. The winner was Aristides, a chestnut colt ridden by Oliver Lewis, one of 13 Black jockeys in a field of 15. Aristides covered the then-standard 1½-mile distance in 2:37¾.

The early Derbies were dominated by Black jockeys — Isaac Murphy, Willie Simms, and Jimmy Winkfield were among the most successful riders of the era. Murphy won three Derbies (1884, 1890, 1891) and is still regarded as one of the greatest jockeys in American history. Winkfield won back-to-back in 1901 and 1902 before emigrating to Europe, where he had a celebrated career.

Growing Pains and the Distance Change (1890s–1910s)

The Derby's early years were not an unbroken success. Attendance fluctuated, finances were difficult, and Clark himself fell into debt. In 1894, a new ownership group took over under Colonel Matt Winn — a pivotal moment in the race's history. Winn became the Derby's greatest promoter, growing it from a regional event into a national institution.

In 1896, the distance was shortened from 1½ miles to the current 1¼ miles — considered the optimal test of a three-year-old thoroughbred's combination of speed and stamina. The change improved the racing quality and helped establish the Derby's identity.

The rose tradition is believed to have begun in 1896 when Clark served roses at a post-Derby social event. By the early 20th century, the blanket of roses had become formalized, and by 1925 it was fully established. In 1982, Churchill Downs president Lynn Stone declared the Kentucky Derby "The Run for the Roses" — a nickname that had already been in informal use for decades.

The Golden Age: War Admiral, Whirlaway, and Citation (1930s–1950s)

The 1930s and 1940s produced some of the most celebrated horses in Derby history. Gallant Fox won the Triple Crown in 1930, becoming only the second horse to do so (after Sir Barton in 1919). His son Omaha won in 1935 — the only father-son Triple Crown winners.

War Admiral (1937) — one of the great racing personalities of the era — swept the Triple Crown and became famous for his duel with Seabiscuit, a horse who never won the Derby but captured the public imagination during the Depression. Their 1938 match race at Pimlico drew a radio audience estimated at 40 million — the largest radio audience for a sporting event to that point in American history.

Whirlaway (1941) — trained by legendary horseman Ben Jones — ran with a distinctive wide-sweeping style, swinging far to the outside before charging past horses on the turn. He won the Triple Crown and set a then-Derby record of 2:01.4.

Citation (1948) may have been the greatest thoroughbred of his era — arguably the finest horse until Secretariat. He won the Triple Crown and 19 of 20 races that year, including the Derby in 2:05.4. He became the first racehorse to earn $1 million in career winnings.

The Greatest Derby Ever Run: Secretariat, 1973

No Derby story is told more often, or with more reverence, than Secretariat's 1973 performance. Trained by Lucien Laurin and ridden by Ron Turcotte, Secretariat ("Big Red") had swept through his two-year-old season as the consensus best horse in America. He arrived at Churchill Downs as the heavy favorite.

What happened on Derby Day 1973 was not just a win — it was a display of unprecedented brilliance. Secretariat broke slowly, was last at the first turn, and then began a sustained acceleration unlike anything seen before. He ran each quarter-mile faster than the last — the exact opposite of how horses usually race, as they tire in the final stages. His final time of 1:59.4 broke the track record by nearly two seconds. It stands as the Derby record today, 53 years later.

Secretariat went on to win the Preakness and then the Belmont Stakes by an astonishing 31 lengths — a performance so extraordinary that it was replayed and studied for decades. His times in all three Triple Crown races remain records. Secretariat is widely considered the greatest thoroughbred racehorse of the 20th century.

Seattle Slew, Affirmed, and the Long Drought (1977–2015)

Seattle Slew (1977) became the only undefeated horse ever to win the Triple Crown — winning all three races without a single career defeat. Affirmed (1978) engaged in one of sport's greatest rivalries: a season-long battle with Aloudar in which the two horses finished first and second in all three Triple Crown races, separated by fractions at every finish. Affirmed won all three; Aloudar was right behind him each time.

After Affirmed, the sport entered a 37-year Triple Crown drought. Between 1979 and 2014, fourteen horses won the Derby and Preakness and then failed at Belmont — often falling to "spoilers" who had skipped the earlier races. The drought became one of the great storylines in American sports, broken annually by hopes and followed by heartbreak.

Memorable Derby winners during this era included Sunday Silence (1989), who beat Easy Goer in a classic rivalry; Charismatic (1999), who won the Derby and Preakness before suffering a catastrophic injury at Belmont that ended his bid; and Smarty Jones (2004), who came closest to ending the drought before finishing second at Belmont in front of 120,000 heartbroken fans.

American Pharoah Ends the Drought — and Justify Repeats (2015, 2018)

American Pharoah (2015) — trained by Bob Baffert, owned by Ahmed Zayat, ridden by Victor Espinoza — finally ended the 37-year Triple Crown drought. His Belmont performance was dominant, winning by 5½ lengths while the crowd of 90,000 roared. It was the most anticipated Belmont Stakes in modern history, and American Pharoah delivered.

Three years later, Justify (2018) — also trained by Bob Baffert, ridden by Mike Smith — became only the second horse in over a century to win the Kentucky Derby without having raced as a two-year-old (the first was Apollo in 1882). Justify won the Triple Crown in dominant fashion, giving Baffert back-to-back crowns and cementing his status as the most successful trainer of the modern era.

The Modern Derby: Upsets, Controversies, and Rich Strikes (2019–2025)

The Derby years since Justify have been defined by dramatic upsets and controversy. In 2019, Maximum Security crossed the wire first but was disqualified after stewards ruled he had impeded other horses during the stretch — the first time in Derby history the winner was disqualified for interference. Country House was elevated to the win.

The 2020 Derby — run in September without fans due to the COVID-19 pandemic — produced a surreal, echoing championship for Authentic, trained by Bob Baffert. In 2021, Medina Spirit crossed the wire first but was later disqualified after a positive drug test, further tarnishing Baffert's legacy and leading to his suspension from Churchill Downs.

The 2022 Derby delivered one of the sport's great shock results: Rich Strike, an 80-1 longshot who had barely made the field as an also-eligible, burst from far back to win in a stunning late charge. Rich Strike's victory — announced over the public address system with shock in the announcer's voice — was an instant classic of the "chaos theory" Derby.

Mage (2023) and Mystik Dan (2024) have been the recent winners, both at odds far above the pre-race favorites. The Derby's unpredictability is not an accident — it is a feature of a 1¼-mile race for three-year-olds that has never been run by any of its 20 entrants before.

Recent Winners (2010–2025)

The Legends — Horses Who Defined the Derby

Secretariat (1973) — The Standard by Which All Are Measured

The record still stands: 1:59.4. Secretariat not only set the Derby record — he did it while starting last and accelerating with every quarter-mile. His final quarter of 23 seconds flat remains the fastest final quarter in Derby history. He is the only horse to run the Kentucky Derby in under two minutes.

Citation (1948) — The Horse That Could Win Anywhere

Citation won 19 of his 20 starts in 1948, including the Triple Crown. He dominated older horses, stake races, and all conditions. Eddie Arcaro — who rode him — called him the best horse he ever rode, and Arcaro rode some of the finest thoroughbreds of the 20th century.

Seattle Slew (1977) — Undefeated and Unstoppable

The only undefeated Triple Crown winner. Seattle Slew was purchased for $17,500 as a yearling and turned into the greatest horse of his generation. His Triple Crown sweep was followed by a storied career as a stallion — his sons and daughters became champions for decades afterward.

American Pharoah (2015) — The End of the Drought

The emotional magnitude of American Pharoah's Triple Crown — 37 years after Affirmed — cannot be overstated. Horse racing had almost given up on ever seeing another Triple Crown champion. When American Pharoah crossed the Belmont wire, the crowd eruption was unlike anything seen at a horse race in the modern era. He was subsequently named Horse of the Year and retired to stud, where he has proven equally dominant.

Rich Strike (2022) — The 80-1 Miracle

Rich Strike barely made the Derby field as a late addition, replacing a scratched horse. He had never been considered a contender. Coming down the stretch at 80-1, he wove between horses and overtook the leaders in the final strides. The racetrack announcer's stunned call — "Rich Strike! Rich Strike at 80-1!" — captured a genuine shock. In a race as unpredictable as the Derby, Rich Strike was its purest expression.

Churchill Downs — The Home of the Derby

Churchill Downs has undergone many transformations since 1875, but its iconic twin spires — added to the grandstand in 1895 — remain the most recognizable image in American horse racing. The spires are so synonymous with the Derby that they have become a cultural symbol far beyond sport.

Churchill Downs is located in Louisville, Kentucky — a city that takes enormous pride in the Derby. The weeks leading up to the race transform Louisville into a festival city, with the Kentucky Derby Festival including the Pegasus Parade, Thunder Over Louisville (one of the largest annual fireworks displays in North America), and the Great Steamboat Race. Louisville's airport, restaurants, and hotels fill to capacity as the horse racing world converges on Kentucky.

The track has been expanded many times — the current facility includes multiple grandstand sections, the famed Skye Terrace, the Eclipse Lounge, and the sprawling infield. But the track itself — the 1-mile oval, the long homestretch, the twin spires — has been essentially unchanged since the late 19th century. History is embedded in the dirt.
