There are some horse racing stories so unlikely that they resist simple retelling. Caughoo is one of them. An 8-year-old bay gelding, trained by a Dublin jeweller's brother and ridden by a work rider who was practically unknown outside Ireland, Caughoo won the 1947 Aintree Grand National at odds of 100/1, defeating fifty-six rivals by twenty lengths. It remains one of the most improbable results in the race's history.
What is less often told is the part Downpatrick played in making that victory possible. In 1945 and 1946, Caughoo won the Ulster National at Downpatrick — the feature handicap chase on the tight, undulating circuit in County Down. Those wins were his preparation, his proof, and his launching pad. Downpatrick was where Caughoo learned to jump, to battle, and to win on demanding ground against real competition. Without those Ulster National victories on the course near Downpatrick Cathedral, the 1947 Aintree triumph would have been even more extraordinary than it already was.
Downpatrick Racecourse has staged racing since 1685, sharing its foundation date with Down Royal across the county. It is one of the oldest continuously operating racecourses in Ireland, and its track — undulating, right-handed, and notoriously testing — has produced tough, adaptable horses. Caughoo is the most famous of them.
This is the story of a horse formed at Downpatrick and immortalised at Aintree. For anyone who wants to understand the history of Downpatrick Racecourse, Caughoo is the place to start. For those who want to know why the Ulster National has produced Grand National winners, Caughoo is the answer.
Caughoo: The Horse
Breeding and Origins
Caughoo was bred in Ireland, a bay gelding whose pedigree did not mark him out as exceptional. He was owned by Dublin jeweller Jack McDowell and trained by Jack's brother Herbert McDowell, who operated on a modest scale compared to the established training operations of the day. The horse was never destined for the showpiece flat races or the high-profile jumping festivals; he was a working jumper in the truest sense, shaped by practical training and regular competition on provincial Irish tracks.
In the late 1940s, the distinction between the racing establishment and the outsiders who occasionally gatecrashed it was starker than it is today. Herbert McDowell was firmly in the second category. He was not a fashionable trainer with wealthy connections and well-placed entries in the Racing Calendar's major races. He trained what he had, used the tracks available to him, and Downpatrick was one of those tracks.
Physical Characteristics
Caughoo was described by those who saw him as small and unimposing — not the physical specimen that traditionally attracts attention on the parade ring. At a time when the Grand National was dominated by big, strong chasers bred for the unique demands of Aintree, Caughoo's appearance would not have inspired confidence from casual observers. The 100/1 price he went off at in 1947 reflected not only his form but also his looks.
What he possessed, and what the Downpatrick track helped develop, was toughness. The Ulster National course at Downpatrick is unforgiving — tight turns, undulating ground, and fences that require precision as much as scope. A horse that won that race twice, back-to-back, was a horse that could jump accurately under pressure and keep finding more when lesser horses stopped.
Early Career
Caughoo's career before his Ulster National wins at Downpatrick was spent largely in Ireland, building experience on the small circuits that the National Hunt calendar offered in the 1940s. Racing in Ireland at this period was less centralised than it became in later decades; provincial fixtures mattered more, and a horse that won consistently on them was a known commodity among those who followed the game closely.
Herbert McDowell brought him through the grades carefully. Caughoo was not a horse that made the transition from bumpers to hurdles to fences with exceptional speed; he was built steadily, his jumping schooled and refined until the trainer was confident he had a horse capable of competing in serious handicap chases.
Ridden by Eddie Dempsey
The choice of Eddie Dempsey as jockey for both the Downpatrick Ulster Nationals and the 1947 Grand National was itself part of the unlikely quality of Caughoo's story. Dempsey was primarily a work rider — not a race jockey of significant reputation. He was known to the McDowell operation but barely recognised beyond it.
Yet Dempsey rode Caughoo consistently well. He understood the horse's way of going, trusted his jumping, and did not ask him to do things beyond his ability. At Aintree in 1947, in a race run in thick fog that reduced visibility significantly, Dempsey guided Caughoo around the course with a calmness that belied his limited profile. The twenty-length winning margin in fog, over a Grand National field, remains one of the most extraordinary riding performances in the race's history.
Temperament
Those who knew Caughoo described him as straightforward and willing, a horse without complications. He did not need complex handling or particular conditions to perform; he turned up, jumped, and ran. This dependability was part of what made the McDowell operation's approach effective. There was no drama in his preparation, no uncertainty about whether he would travel or perform in unfamiliar environments. He arrived at Aintree in 1947 as a horse who had won twice at Downpatrick and been pointed at the biggest race in the world. He simply did what he had always done.
The Races at Downpatrick
The Ulster National at Downpatrick
The Ulster National is Downpatrick's most significant race — a long-distance handicap chase that tests horses over a trip comfortably beyond three miles on a track that demands versatility. The course runs right-handed, undulating through the countryside of County Down, with fences that are solidly built and placed on ground that can change character with the weather.
For a Grand National preparation, Downpatrick's Ulster National is as demanding a trial as exists on the Irish racing calendar. The distance requires stamina. The tight turns test jumping precision. The competitive field — drawn from the best staying chasers available at the time — ensures that a winner has earned it rather than coasted through lesser opposition.
Caughoo won the race in 1945, then returned to win it again in 1946. Two consecutive wins in the Ulster National were a serious statement. The McDowell operation had demonstrated that they had a horse capable of winning a real race — not a small novice event or a modest handicap, but the leading staying chase run in Northern Ireland.
Why Downpatrick Mattered for Grand National Preparation
The connection between Downpatrick and Aintree is not accidental. Both races demand the same fundamental qualities: jumping accuracy over big fences, the stamina to run long distances at racing pace, and the mental durability to keep competing when tired. A horse that could win the Ulster National twice was a horse with a demonstrable set of skills applicable to Grand National conditions.
Herbert McDowell understood this when he planned the 1947 campaign. The Aintree entry was ambitious — extravagantly so, given that Caughoo was starting at 100/1 — but it was grounded in the evidence of what the horse had done at Downpatrick. He had won a tough race on a demanding course, twice, under pressure. There was a foundation for the ambition.
The 1947 Grand National
On 5 April 1947, Caughoo lined up at Aintree with fifty-six rivals in a race run in notoriously thick fog. The conditions reduced visibility to a level that made spectating practically impossible from the stands; jockeys navigated by sound and instinct as much as sight. In those circumstances, a horse with Caughoo's straightforward jumping technique and Eddie Dempsey's calm guidance had an advantage that the odds did not reflect.
He jumped the course with accuracy, avoided the catastrophes that befell many rivals, and emerged from the fog to win by twenty lengths. The result caused astonishment at Aintree and across Ireland. The 100/1 winner, trained by a jeweller's brother, ridden by a work rider, formed at a provincial Irish track — it had the quality of fiction.
Downpatrick's Place in the Story
Downpatrick Racecourse holds Caughoo memorabilia that connects the course to his victory. The track itself has not fundamentally changed in character since Caughoo ran there; it remains demanding, intimate, and right-handed, with the same requirement for jumping accuracy and stamina that it asked of him in 1945 and 1946.
The Ulster National, now sponsored by Randox and run each spring, continues to attract competitive fields of staying chasers. It is the same race Caughoo won, run over the same ground. For those who visit Downpatrick on race day, the connection to his story is a live part of the course's identity, not merely a historical footnote.
The Course's Other Races
Downpatrick stages a small number of fixtures each year — typically around ten meetings — with the Ulster National as the highlight. The card on National day includes hurdle and chase races across varying distances, providing a full programme for the course's most significant fixture.
The track, described in detail in the Downpatrick complete guide, rewards horses with sound jumping and real stamina. Those were Caughoo's qualities, and they are the same qualities that the Ulster National continues to test. The Gold Cup — the Downpatrick Gold Cup — is the other feature race on the calendar, typically run later in the season.
Great Moments
The First Ulster National Win, 1945
Caughoo's first Ulster National victory at Downpatrick in 1945 was the moment that placed him on the map in Irish racing. He was not a highly fancied horse — his connections operated without the publicity machine that surrounded more fashionable yards — but the performance on the tight Downpatrick circuit made a clear impression on those who watched.
The wartime and immediate post-war period in Irish racing was characterised by limited resources and reduced fields, but the competitive quality of the Ulster National was not diminished. Winning it required a horse to handle Downpatrick's particular challenges: the undulating ground, the right-handed turns, the stamina sapping distance. Caughoo cleared all of those hurdles in 1945 and announced himself as a real contender for major races.
The Second Ulster National Win, 1946
Returning the following year to win again was the more significant achievement. A first win can be fortune; a second wins over the doubters. Caughoo's 1946 Ulster National victory confirmed that his 1945 win was not an accident. He had the ability, the temperament, and the jumping technique to win a race of this standard consistently.
For Herbert McDowell, the two wins justified the decision to keep the horse in training and pointed toward more ambitious targets. The 1947 Grand National entry was made with the knowledge that Caughoo had proven himself at a high level in Irish racing. The 100/1 price reflected unfamiliarity among British bookmakers and British racegoers, not the evidence of the horse's form.
Aintree in Fog, 5 April 1947
The circumstances of the 1947 Grand National have been debated ever since. The fog at Aintree that day was so thick that the race was almost run in darkness — jockeys could barely see beyond the horse in front. In conditions like these, the Grand National becomes less a test of raw speed and more a test of jumping reliability and positional intelligence.
Caughoo's attributes suited those conditions precisely. He was a clean jumper who did not require seeing a fence from distance to measure his take-off correctly. Eddie Dempsey, who knew the horse intimately, kept him balanced and running, trusting Caughoo's instincts over the obstacles. They did not challenge for an early lead; they stayed in a position that allowed them to jump cleanly and pick up the pieces as others fell or tired.
When he emerged twenty lengths clear at the finish, the result was met with near-disbelief. Questions were raised in the years that followed about whether Caughoo had cut the course — taken a shortcut in the fog — and the controversy periodically resurfaces in histories of the Grand National. Contemporary evidence and detailed examination of the accounts suggest these allegations were not substantiated, but the fog meant certainty was impossible. The record books give the race to Caughoo and that has not changed.
The Legacy Moment at Downpatrick
Perhaps the most affecting aspect of Caughoo's story, from Downpatrick's perspective, is the simplicity of it. A horse trained on the course, winning the course's most important race twice, went to Aintree and won the world's most famous steeplechase. There is a directness to that narrative — form at Downpatrick, vindication at Aintree — that makes it both credible and extraordinary.
The memorabilia held at Downpatrick Racecourse gives a physical grounding to the story. Racegoers who visit the course can connect to the history in a tangible way. The paddock, the fences, the undulating back straight — these are the same elements Caughoo encountered in 1945 and 1946. The landscape has not changed fundamentally. That continuity makes the history present rather than distant.
Legacy & Significance
What Caughoo Means for Downpatrick
Caughoo is Downpatrick's greatest racehorse. That claim requires no qualification. He won the Ulster National twice at the course and went on to win the Grand National at Aintree, and his connection to Downpatrick is explicit: without the course, the career as it unfolded would not have been possible.
For a small, provincial racecourse with limited resources and a modest schedule of fixtures, having a Grand National winner in its history is a distinction of notable significance. Downpatrick stages around ten meetings a year; it does not have the financial firepower or the profile of the major Irish tracks. Yet Caughoo gives it a historical standing that outweighs its size. The 1947 Grand National winner came from here. That fact does not diminish.
The Ulster National's Credibility
Caughoo's Grand National win reinforced the credibility of the Ulster National as a real test of National Hunt quality. The race is not run at Cheltenham or Leopardstown, and its winners do not always find their way onto the front pages of the racing press. But the ability to produce a horse capable of winning the Grand National from its graduates is the most persuasive argument any race can make.
In subsequent decades, the Ulster National continued to attract competitive fields and produce winners who went on to perform at a high level. The Caughoo precedent is part of that story — a demonstration that a race run on a demanding course over a long distance can produce the real thing.
The Controversy and the Record
The fog at Aintree in 1947 and the questions raised about Caughoo's route around the course have never been definitively resolved to everyone's satisfaction. The controversy is part of his story. Those who believe he won fairly — and the weight of evidence does not support the shortcut allegation — point to his form at Downpatrick as evidence of real ability. A horse that won the Ulster National twice could win the Grand National honestly.
Those who look at the 100/1 price, the work rider jockey, and the impenetrable fog and remain sceptical have grounds for their doubt. Racing history is full of contested results, and the 1947 Grand National sits in a category of its own.
What remains true regardless of the controversy is that Downpatrick Racecourse holds the memorabilia, holds the connection, and holds the story. The course was where Caughoo's reputation was built. Whatever happened at Aintree, that part of the record is clear.
A Horse for the History of County Down
Racing in County Down has a character distinct from the major urban tracks. Down Royal and Downpatrick are both old, both right-handed, both part of a racing culture that is provincial in the best sense — intimate, knowledgeable, and fiercely proud of its horses. Caughoo embodies that culture.
He was not a horse produced by a fashionable training establishment with wealthy patronage. He was produced by a family operation, on a small course, in conditions that were far from glamorous. His Grand National win in 1947 was the sport at its most democratic: an outsider, from outside the establishment, winning the biggest race in the world.
