Irish runners who could feature in the 2025 Prix de l’Arc de Triomphe

Ireland has long been a powerhouse in the world of flat racing, yet recent history shows how elusive Europe’s most prestigious middle-distance prize has become for Irish-trained horses. Found’s memorable win in 2016 remains the most recent triumph for the Emerald Isle—and just the fourth this century. But could 2025 be the year the drought ends?
With the autumn showpiece at Longchamp fast approaching, we’ve looked at the leading Irish contenders who could line up in this year’s Prix de l’Arc de Triomphe.

Minnie Hauk
Minnie Hauk ended last year with a maiden fillies’ success at Leopardstown on her second start in October and has progressed into a very classy three-year-old.
The daughter of Frankel kicked off this campaign with a win in the Listed Cheshire Oaks at Chester, and she added yet another Classic to Aidan O’Brien’s CV when winning the Oaks.
Minnie Hauk just held off a fierce challenge from her stablemate Whirl by a neck to win the prestigious Epsom contest and is a worthy ante-post favourite for the Arc.
Whirl
Speaking of Whirl, she’s another potential runner for Ballydoyle as O’Brien and Coolmore seek to win their first Arc since the aforementioned Found almost a decade ago.
Whirl bounced back from a lacklustre reappearance at the Curragh when comfortably landing the Group 3 Musidora at York—beating Serenity Prayer.
After being narrowly denied by her companion Minnie Hauk, Whirl returned to winning ways again at the Curragh, winning a first Group 1 when scoring from Kalpana in the Pretty Polly Stakes.
Lambourn
Lambourn is a dual Derby winner this campaign, winning both the British and Irish versions of the race in fine style.
However, many pundits and punters are still questioning his ability based on the quality of the fields in those Classics this season.
However, if he were to win an Arc, there would be no doubt that Lambourn is as good as the races he has won this season.
O’Brien hasn’t dismissed a crack at Longchamp either, saying: “He could be a King George or an Arc type of horse.
“The way he races, I’d imagine he’d race that way regardless of the trip. You’d imagine he’d get further, but he has lots of class.”
Jan Brueghel
Another potential runner for O’Brien, Jan Brueghel is versatile over a range of distances, and his recent Coronation Cup success could set him up nicely for an Arc tilt.
After rounding off last season with a win in the St Leger, beating stablemate Illinois by a neck, but was beaten on reappearance over one mile and two furlongs at the Curragh.
He was back to his best on return to a mile and a half at Epsom, staying on gamely from French raider Calandagan to win the Coronation Cup.
Of course, Secretariat was arguably the greatest racehorse of the second half of the twentieth century and will always be remembered as the ninth winner of the American Triple Crown – that is, the Kentucky Derby, Preakness Stakes and Belmont Stakes – in 1973. All told, the son of 1957 Horse of the Year Bold Ruler won 16 times and amassed a total of $1.32 million in prize money, or $9.1 million in modern terms, based on Consumer Price Index (CPI) data. Secretariat was, himself, named Horse of the Year in both 1972 and 1973.
Every now and then, a horse comes along that changes the entire atmosphere of a race day. Not just for the crowd or the camera crews, but for the bookmakers and the bettors. Frankel did it. So did Flightline. They don’t just win. They pull the entire sport into their orbit. And when horses like that line up at the start, betting habits shift in ways that go far beyond the odds.
