The Legend of Arkle: Ireland’s Unbeatable Racehorse

The Arkle horse is the name British and Irish racing reaches for whenever it needs a benchmark. He won three Cheltenham Gold Cups in a row, carried crushing weights to victory in the biggest handicaps of the day, and forced the Irish authorities to publish two separate sets of weights for the same race: one for when he ran, and one for when he did not. His Timeform rating of 212 remains the highest ever awarded to a steeplechaser, more than half a century after his final race.

This guide covers where Arkle came from, how he was bred and trained, the Mill House rivalry that turned him into a national figure, exactly what he achieved under top weight, and why his name still carries weight every March at the Cheltenham Festival.

Arkle at a glance: the essential facts

If you have arrived here looking for one specific detail about the Arkle horse, this table covers the questions asked most often.

Early life and breeding

Ballymacoll Stud, 19 April 1957

Arkle was foaled on 19 April 1957 at Ballymacoll Stud in County Meath, bred by Mary Baker of Malahow House, near Naul, County Dublin. He was a bay, and was gelded before his racing career began. On pedigree alone, nothing pointed to greatness. His sire, Archive, never won a race of any consequence, though he came from a blue-blooded Thoroughbred line: Archive was a son of Nearco, the unbeaten Italian-bred champion who became one of the most influential stallions of the twentieth century. His dam, Bright Cherry, was the more obvious source of jumping ability, having won over fences herself.

That combination, a well-bred but unproven sire over a genuine jumping mare, was typical of the Irish half-bred and Thoroughbred jumping stock of the period, the same tradition that produced the Irish Draught influence found throughout National Hunt pedigrees.

A 1,150-guinea purchase at Goffs

In August 1960, the three-year-old gelding was offered at Goffs Bloodstock Sales in Dublin. Tom Dreaper, the leading National Hunt trainer in Ireland at the time, bid 1,150 guineas on behalf of Anne, Duchess of Westminster. It was a modest sum even by 1960 standards, and no one in the ring had any reason to think otherwise. Within four years the horse bought for that money would be reshaping the way Irish handicaps were framed.

Named after a Scottish mountain

The Duchess named him after Arkle, a mountain in Sutherland in the far north-west of Scotland, which bordered her Scottish estate. She had a long-running habit of naming her horses after landmarks on the estate. The choice proved apt: like the mountain, Arkle came to stand alone.

How big was Arkle?

Arkle stood 16.2 hands high, measured in the standard way from the ground to the withers. That made him a big, rangy chaser but not a giant, and notably he was not the physically imposing one in his own greatest rivalry. Mill House, the horse he displaced, was the one nicknamed “The Big Horse”. Contemporary accounts consistently describe Arkle’s advantage as being one of athleticism, balance and conformation rather than sheer scale.

Training and the making of a chaser

Tom Dreaper’s Greenogue yard

Dreaper trained at Greenogue, near Kilsallaghan in north County Dublin, and ran a yard known for patience rather than pyrotechnics. He had already trained Prince Regent, the 1946 Cheltenham Gold Cup winner, and would later train Flyingbolt, whose Timeform rating of 210 is the second-highest ever given to a steeplechaser, behind only Arkle himself. That Dreaper had the two highest-rated chasers in history in his stable at the same time says a great deal about the operation he ran.

From bumpers to hurdles to fences

Arkle made his racecourse debut on 9 December 1961 in a bumper at Mullingar, finishing third of 17. He did not win first time out, and several of his early efforts looked workmanlike rather than electric. His first win came on 20 January 1962 in the Bective Novice Hurdle at Navan. By the end of that season he had announced himself, and the decision was taken to send him over fences the following autumn. He never fell in his entire career.

Pat Taaffe: the partnership that defined him

Pat Taaffe became Arkle’s regular jockey and rode him in all of his major victories. Taaffe was a tall, quiet horseman who already understood Dreaper’s horses, and the pair turned raw power into rhythm and precision. Paddy Woods rode Arkle in much of his work at home. The Taaffe partnership is among the most celebrated in National Hunt history, and Taaffe later wrote a memoir of the horse.

The Mill House rivalry

Mill House: “The Big Horse”

Every great champion needs an opponent worth the title, and Arkle’s was Mill House. Trained in Lambourn by Fulke Walwyn for owner William Gollings, Mill House won the 1963 Cheltenham Gold Cup as a six-year-old and was nicknamed “The Big Horse” for his size and presence. He was no paper rival: Timeform rated him 191, a figure that would make him a champion in most eras. He had the misfortune to be foaled in the same decade as Arkle.

The 1963 Hennessy: Arkle beaten into third

Their first meeting came in the Hennessy Gold Cup at Newbury in November 1963. Mill House, the reigning Gold Cup winner, started favourite despite conceding 5lb to Arkle, and won. Arkle could finish only third after making a bad mistake at the third-last fence. Pat Taaffe was adamant afterwards that the error, not the horse, was the difference between winning and losing. English racing was not convinced, and the argument ran all winter.

Cheltenham Gold Cup, March 1964

The rematch was the 1964 Cheltenham Gold Cup, and it settled the argument permanently. Mill House started 8/13 favourite; Arkle was 7/4. The two matched strides up the Cheltenham hill before Arkle went clear to win by five lengths. It was the race that broke Mill House and made Arkle.

Every Arkle and Mill House meeting

The pair met five times in total. Mill House won the first. Arkle won the other four, each more decisively than the last.

Three Cheltenham Gold Cups (1964 to 1966)

1964: five lengths over Mill House

The 1964 Gold Cup was a small, high-class affair. Arkle’s five-length win on his first attempt set the template for what followed: travel kindly, go to the front whenever asked, jump cleanly under pressure.

1965: a 20-length annihilation

A year later the Gold Cup turned into one of the most lopsided contests in the race’s history. Arkle won by 20 lengths from Mill House. Whatever doubt had survived 1964 did not survive this.

1966: 30 lengths from Dormant

In the 1966 Cheltenham Gold Cup, Arkle won by 30 lengths from Dormant. He had now carried his form through three full seasons at the very top of the sport, and he was still only nine years old.

Where three in a row sits in Gold Cup history

Arkle’s hat-trick is often described as unique. It is not, and the real context is more interesting. Four horses have won the Cheltenham Gold Cup three or more times:

• Golden Miller: five in a row, 1932 to 1936, still the outright record
• Cottage Rake: three in a row, 1948 to 1950
• Arkle: three in a row, 1964 to 1966
• Best Mate: three in a row, 2002 to 2004

Arkle was therefore the third horse to complete the treble, not the first, and Best Mate was the fourth. Al Boum Photo, the most recent multiple winner, took the 2019 and 2020 renewals back to back but did not add a third. What separates Arkle from the others on that list is not the hat-trick itself. It is that he did it while simultaneously giving away up to two stone in the best handicaps in Britain and Ireland, which none of the others attempted.

Handicaps and the Arkle weight scale

Two sets of weights for one race

Handicaps are supposed to level the playing field by loading the best horse with the most weight. Arkle broke the system. Irish handicappers began framing races with two separate sets of weights, an A scale to be used if Arkle ran and a B scale if he did not, because a single set could not accommodate him and produce a competitive race for everyone else.

In the 1964 Irish Grand National at Fairyhouse he carried 30lb more than his rivals and won by one length. The margin looks narrow until you register the weight concession behind it.

The major handicap haul

Beyond the three Gold Cups, his major victories included the following. The recurring 12st 7lb is the point: it is the maximum weight in these races, and winning under it repeatedly is close to unheard of.

The Whitbread win on 12st 7lb brought him the largest single prize of his career to that point, £8,230. He also won the Leopardstown Chase three times. The Hennessy is now run as the Coral Gold Cup, but the weights Arkle carried in 1964 and 1965 still stand out in the historical record more than sixty years on.

Career record by the numbers

Arkle ran 35 times under Rules. He won 27, was second twice and third three times, meaning he finished out of the first three on only three occasions in his entire career. Over fences specifically, he won 22 of his 26 starts.

The 212 figure is worth dwelling on. Timeform, which has rated racehorses on a consistent scale since 1948, has never matched it in the decades since. Flyingbolt sits second on 210. Below that the gap widens sharply: Mill House and Kauto Star are rated 191, Sprinter Sacre 192p. On the only scale that allows generations to be compared directly, Arkle is not narrowly ahead of the field. He is twenty-odd pounds clear of almost everything that has ever jumped a fence.

“Himself”: personality and the Guinness story

Fan mail addressed to “Arkle, Ireland”

Arkle attracted a following well beyond the racing public, and in Ireland he was known simply as “Himself”. Fan mail arrived at the Greenogue yard from around the world, some of it addressed to nothing more specific than “Arkle, Ireland”, and it reached him. He was easy-going at home, more interested in his routine than in showing off. The contrast between his manners around the yard and his ferocity over a fence was a large part of why people warmed to him.

Two pints of Guinness a day

The story is true, and it is better documented than most racing folklore: two pints of Guinness were added to his daily feed of oats. Whether the stout did anything physiologically is doubtful, and no modern yard would build a feeding regime around it. Whether it added to the legend is not in question at all. It remains the single most repeated fact about the horse.

The injury that ended it

King George VI Chase, 27 December 1966

Arkle’s career ended at Kempton Park in the 1966 King George VI Chase. Jumping the open ditch, he struck the guard rail with a hoof and fractured his pedal bone, the bone encased within the hoof capsule. Astonishingly, he raced on and finished second to Dormant, beaten by a horse he would have dismissed on any sound day. He was nine years old and at the height of his powers.

A fractured pedal bone is a serious injury in any horse and was close to a death sentence for a top-class chaser in 1966. Arkle was in plaster for four months. Modern veterinary medicine treats such fractures far more successfully, just as it has changed the outlook for other conditions of the equine foot such as navicular syndrome, but the options available at the time were limited.

Retirement, decline and death

He recovered well enough to go back into training, which in itself was regarded as remarkable, but he never ran again and his retirement was formally announced in 1968. He spent it at the Duchess of Westminster’s Bryanstown estate near Maynooth, where he was ridden as a hack. In 1969 his condition deteriorated and he began to show stiffness in his hind legs, possibly the result of arthritis. On 31 May 1970 he was put down on humane grounds, aged only 13.

Legacy: records and honours

The Arkle Challenge Trophy

The Cheltenham Festival’s championship two-mile novices’ chase is run as the Arkle Challenge Trophy, a Grade 1 contest traditionally staged on the opening day. Winners include Klairon Davis, Moscow Flyer, Sprinter Sacre, Altior, Energumene and Marine Nationale, which gives some sense of the company the race keeps. For many trainers, winning the Arkle is the clearest signal they have a genuine Gold Cup horse on their hands.

Statues, the skeleton and the museums

A bronze statue of Arkle sculpted by the Royal Worcester artist Doris Lindner was unveiled at Cheltenham Racecourse by the Duchess of Westminster in 1972. A second statue stands in Ashbourne, County Meath. His skeleton, exhumed in 1976, is on permanent display at the Irish National Stud at Tully, County Kildare, and the National Horseracing Museum at Newmarket holds material from his career.

Why he is still the benchmark

Every generation produces a new champion, and every generation hears the same question: was he as good as Arkle? The honest answer is that the ratings have not come close. Until somebody beats 212, Arkle remains the horse against whom the others are measured.

Frequently asked questions

How many Cheltenham Gold Cups did the Arkle horse win?

Arkle won the Cheltenham Gold Cup three times in succession, in 1964, 1965 and 1966. He was the third horse to win three or more consecutive Gold Cups, after Golden Miller (five in a row, 1932 to 1936) and Cottage Rake (1948 to 1950). Best Mate later became the fourth, winning from 2002 to 2004.

How tall was Arkle?

Arkle stood 16.2 hands high. He was a big, athletic chaser, though not the largest horse in his own generation: his rival Mill House was nicknamed “The Big Horse” for good reason.

Did Mill House ever beat Arkle?

Yes, once. Mill House beat Arkle in the Hennessy Gold Cup at Newbury in November 1963, when Arkle finished third after a bad mistake at the third-last. They met five times in total and Arkle won the remaining four, by margins that grew from five lengths to twenty.

Did Arkle ever run in the Grand National?

No. Arkle never contested the Aintree Grand National. He did win the 1964 Irish Grand National at Fairyhouse, carrying 30lb more than his rivals and winning by one length.

What was Arkle’s race record?

Arkle ran 35 times, winning 27, finishing second twice and third three times. Over fences he won 22 of his 26 starts, and he never fell in any race. His Timeform rating of 212 remains the highest ever given to a steeplechaser.

What happened to Arkle and how did he die?

Arkle fractured his pedal bone in the King George VI Chase at Kempton on 27 December 1966 after striking the guard rail of the open ditch, and still finished second. He spent four months in plaster and recovered enough to return to training, but never raced again and was formally retired in 1968. He lived at the Duchess of Westminster’s Bryanstown estate until his condition deteriorated with stiffness in his hind legs, possibly arthritis, and he was put down on humane grounds on 31 May 1970, aged 13.
