Famous Racehorses of All Time
From Secretariat's 31-length Belmont to Frankel's 14 unbeaten races — profiles of the horses that defined racing eras, broke records, and shaped the thoroughbred breed.
Modern Era Champions
The greatest horses from 1950 to the present day.
Secretariat
1970–1989 · United States
The greatest American racehorse — Secretariat's 1973 Belmont Stakes by 31 lengths in a world record 2:24 remains the most extraordinary single race performance in thoroughbred history.
Secretariat — a chestnut son of Bold Ruler bred by Meadow Stable — is the defining American racehorse: the 1973 Triple Crown winner whose Belmont Stakes performance (31 lengths, 2:24, still the course and world record over 50 years later) is the most physically astonishing result in the sport's history. His cardiovascular system, examined post-mortem, was reportedly twice the normal size for a thoroughbred. His times in all three Triple Crown races were records; his Preakness time was subsequently confirmed as a record only after Pimlico's timing equipment error was corrected decades later.
Frankel
2008–2012 · United Kingdom
The world's highest-rated horse in Timeform's 65-year history — Frankel won all 14 races unbeaten, including the 2012 Queen Anne Stakes at Royal Ascot by 11 lengths.
Frankel — a bay son of Galileo bred by Juddmonte Farms, trained by the late Sir Henry Cecil — is rated by Timeform at 147, making him the highest-rated horse in the organisation's 65-year history. His 14-race unbeaten career spanned two seasons of elite European flat racing, with victories at distances from 7 furlongs to 1½ miles — a range that demonstrated both extreme speed and genuine stamina. His final race, the 2012 Champion Stakes at Ascot, was his farewell appearance and produced a performance that his trainer Cecil (who was battling stomach cancer throughout Frankel's career) described as 'the perfect race.' Cecil passed away eight months later.
Winx
2012–2019 · Australia
The most prolific consecutive winner in modern thoroughbred history — Winx won 33 consecutive races including 25 Group 1 victories over five years in Australia.
Winx — a bay mare bred in New Zealand and trained by Chris Waller — won 33 consecutive races from 2015 to 2019, including 25 Group 1 victories, making her the most prolific Group 1 winner in history. Her dominance of Australian weight-for-age races — particularly the Cox Plate (won four consecutive times, a record) and the Turnbull Stakes — was so complete that bookmakers refused to take significant bets on her final appearances. Her retirement race, the 2019 Queen Elizabeth Stakes at Randwick, was watched by 40,000 spectators and generated unprecedented Australian racing media coverage.
Arkle
1957–1968 · Ireland
The greatest steeplechaser in history — Arkle's three consecutive Cheltenham Gold Cups (1964, 1965, 1966) were won so dominantly that the handicapper created a separate weight scale for him.
Arkle — a bay gelding bred in Ireland and trained by Tom Dreaper for Anne, Duchess of Westminster — is the definitive steeplechaser: three consecutive Cheltenham Gold Cups (1964, 1965, 1966), multiple King George VI Chases, and a reputation so dominant that the Irish and British handicappers created a separate weight assessment for him — races were handicapped 'with Arkle' and 'without Arkle' as separate divisions. His rivalry with Mill House (the 1963 Gold Cup winner, regarded as the horse of the century before Arkle appeared) defined the mid-1960s jump racing era. A fractured pedal bone sustained in the King George in December 1966 ended his racing career; he never raced again.
Nijinsky
1967–2000 · Ireland/Canada
The last British Triple Crown winner — Nijinsky's 1970 season produced the Guineas, Epsom Derby, and St Leger in sequence, a feat no horse has replicated in over 55 years.
Nijinsky — a Canadian-bred son of Northern Dancer, trained by Vincent O'Brien — was the last horse to win the British Triple Crown (2,000 Guineas, Epsom Derby, St Leger) in 1970, a feat that has not been repeated in over 55 years. His two defeats that year — in the Prix de l'Arc de Triomphe (ran with a ringworm scar affecting his coat) and the Champion Stakes (second start after the Arc) — came at the end of an extraordinary season that had included the Triple Crown plus the Irish Derby and King George VI and Queen Elizabeth Stakes. As a stallion, Nijinsky became one of the most influential sires in thoroughbred history, producing multiple champion sires who have shaped the modern thoroughbred pedigree.
Black Caviar
2007–2013 · Australia
Australia's greatest sprinter — Black Caviar won all 25 races unbeaten including 15 Group 1 victories and a Royal Ascot triumph that brought 8,000 Australians to Berkshire.
Black Caviar — a grey mare trained by Peter Moody in Melbourne — won all 25 races including 15 Group 1 victories, making her Australia's most prolific Group 1-winning sprinter. Her 2012 Royal Ascot appearance in the Diamond Jubilee Stakes — won in what was subsequently judged to be a compromised performance (she was eased near the line by Luke Nolen when clearly feeling the effects of her long journey) — became the moment that defined Australian racing's international ambition: an estimated 8,000 Australians made the trip to Berkshire to watch her race.
Enable
2014–2020 · United Kingdom
Back-to-back Arc winner and the dominant European mare of the modern era — Enable's consecutive Arc victories in 2017 and 2018 were the highlight of six seasons of elite middle-distance racing.
Enable — a bay filly (later mare) by Nathaniel, trained by John Gosden for Juddmonte Farms — won back-to-back Prix de l'Arc de Triomphe in 2017 and 2018, following an attempt at a third Arc in 2019 that ended in defeat by Waldgeist. Her six-season career included victories in the Oaks, King George VI and Queen Elizabeth Stakes (twice), and multiple international Group 1 races. Her attempt at an unprecedented third Arc in 2020 — at age six, after a year off due to injury — produced a creditable fourth as the oldest horse in the field.
Sea-Bird
1962–1973 · France
The most dominant Arc winner of all time — Sea-Bird's 1965 Arc de Triomphe victory by 6 lengths over the best European field of the decade established him as Timeform's all-time highest-rated flat horse.
Sea-Bird — a chestnut son of Dan Cupid trained by Etienne Pollet — ran eight times and won eight times, culminating in the 1965 Prix de l'Arc de Triomphe, won by an easing-up 6 lengths from Reliance, with Diatome (who ran 2nd in the Washington DC International next time) third. Timeform rated him 145 at his peak — matching or exceeding Frankel's figure depending on the era adjustment applied — and the 1965 Arc field is considered the deepest in the race's history. Sea-Bird never raced again after the Arc; his subsequent career as a stallion was disappointing, which remains one of racing's most frustrating breeding mysteries.
Cigar
1990–1996 · United States
America's Horse of the 20th Century (People's Vote) — Cigar's 16 consecutive wins from 1994 to 1996, including the Breeders' Cup Classic and Dubai World Cup, revived American racing during a period of waning national interest.
Cigar — a bay gelding by Palace Music, trained by Bill Mott — won 16 consecutive races from late 1994 through August 1996, equalling Citation's US record for consecutive wins. His run included the 1995 Breeders' Cup Classic at Belmont Park and the inaugural Dubai World Cup in 1996 — becoming the first major international horse to win at Meydan and establishing the race's global credibility in its inaugural running. Cigar was voted America's Horse of the 20th Century in a public vote in 1999, narrowly defeating Man o' War and Secretariat — a result that reflected his accessibility to a generation of racing fans who could watch him in real-time.
Historic Legends
Racing greats from before the modern era whose records remain unbroken.
Kincsem
1874–1887 · Hungary
The most prolific unbeaten racehorse in history — Kincsem won all 54 of her races from 1876 to 1879 across five countries including Austria-Hungary, Germany, France, and England.
Kincsem — meaning 'my treasure' in Hungarian — is the most prolific unbeaten thoroughbred in recorded history: a chestnut mare who won all 54 of her races between 1876 and 1879 across Austria-Hungary, Germany, France, and England. Her Goodwood Cup victory in England confirmed her as a genuine international champion rather than merely a Central European curiosity. Her physical characteristics were reportedly unusual — large and heavy-boned, defying the classical ideal — but her cardiovascular capacity was apparently extraordinary. She was accompanied everywhere by a cat who slept in her box. Budapest's Kincsem Park carries her name and legacy.
Man o' War
1917–1947 · United States
The first great American racehorse — Man o' War's single loss (to Upset at Sanford Memorial) gave English its word for a shocking result, and his 20 wins included defeating older horses as a two-year-old.
Man o' War — a chestnut son of Fair Play, foaled in 1917 — is the horse from whom the American thoroughbred's physical standard is still measured, known as 'Big Red' for his distinctive copper-chestnut coat and extraordinary size. His 20 wins from 21 starts include defeats of older horses in weight-for-age competition as a three-year-old, a feat of extraordinary quality given the competitive depth of American racing in 1920. His single loss — to Upset in the 1919 Sanford Memorial at Saratoga — gave English the word 'upset' as a term for an unexpected defeat. His trainer kept him in a specially built barn after retirement, where he received visitors for over 25 years until his death in 1947.
Phar Lap
1926–1932 · Australia/New Zealand
Australia's greatest sporting icon — Phar Lap won 14 consecutive races including the 1930 Melbourne Cup and died under mysterious circumstances in the United States in 1932.
Phar Lap — a bay gelding bred in New Zealand and trained in Australia — won 37 races including the 1930 Melbourne Cup (by 3 lengths) and was so dominant in Australian racing that the handicapper attempted to make him unraceable by assigning extraordinary weights. His owners sent him to America in 1932 for the Agua Caliente Handicap in Mexico, which he won in track-record time. He died 17 days later in suspicious circumstances that have never been definitively explained — possibly arsenic poisoning, possibly a medication overdose. His stuffed hide is preserved in Melbourne Museum; his skeleton is in Te Papa Tongarewa in Wellington; his heart (weighing 6.35kg, more than twice the normal thoroughbred heart) is in the National Museum of Australia.
