The great and the good of British and Irish racing have long understood that the Prix de l'Arc de Triomphe is no ordinary contest. It is the supreme test of the thoroughbred, a race that separates the champions from the also-rans, and a cornerstone of the breeding industry that sustains our sport. Now, in a move that has sent shockwaves through the paddock, the mighty Coolmore operation has thrown its considerable weight behind a campaign to stop France Galop from opening the race to geldings.
John Magnier, the Coolmore supremo, and his trusted lieutenant Aidan O'Brien, have been vocal in their opposition to the proposed change, which would allow geldings to contest Europe's most prestigious prize from next year. Their intervention, in the form of a statement posted on social media under the banner 'Protect the Prix de l'Arc de Triomphe', urges all those with a stake in the sport to sign a petition against the move. It is a classic piece of Coolmore muscle, deployed in defence of a tradition that many fear is being eroded by modern commercial pressures.
Why is Coolmore opposing the change?
At the heart of the matter lies a simple but profound concern. The Arc, run over a mile and four furlongs at Longchamp, has always been a race for the very best colts and fillies, animals destined to shape the future of the breed. To admit geldings, Magnier argues, would be to undermine the very essence of the contest. 'I hope they don't let the geldings into the Arc,' he said in June. 'I think most of the purists would be against it. There are two sides to every coin but I'm only giving it from the breeding side and from the breed as a whole. The Arc is one of the real races and it won't be any more if you include geldings.'
O'Brien, the master of Ballydoyle, has been equally forthright. 'It's so much easier to train a gelding, they will have an unfair advantage in the race,' he warned, highlighting a practical concern that resonates with trainers up and down the country. A gelding, freed from the distractions of the breeding shed, can devote his entire being to the track. To pit him against colts who may be thinking of other matters is, in the eyes of the traditionalists, a travesty.
Who started the petition and what does it say?
The petition itself was launched by Henri Bozo, the prolific French breeder and director of Ecurie des Monceaux, and the man who bred Diamond Necklace. It argues that opening the Arc to geldings would not only diminish its unique status as a premier race for future breeding prospects but could also deter connections of three-year-olds and reduce opportunities for emerging talent. The wider consequences for thoroughbred breeding, the petition warns, could be severe, and it calls for proper consultation with owners, trainers and breeders before such a fundamental change is made.
By Friday morning, the petition had already attracted around 500 signatures. Coolmore's endorsement, announced on Thursday evening, is likely to swell those numbers considerably, such is the respect in which the operation is held across the globe.
What has France Galop said in response?
France Galop, the sport's governing body across the Channel, has shown little appetite for compromise. In June, its board gave 'overwhelming approval' to a proposal put forward by its president, Guillaume de Saint-Seine, to open the Arc to geldings. The decision was subsequently approved by the European Pattern Committee last month following a member vote.
De Saint-Seine has welcomed the change, insisting it 'will make the race even more compelling on the track and further strengthen its international profile and media appeal'. It is a view that has gained momentum, not least because of the exploits of the Francis Graffard-trained pair Goliath and Calandagan. Both won the King George VI and Queen Elizabeth Stakes at Ascot, yet were ineligible for France's biggest race. Their connections, and many neutrals, saw this as an absurdity that needed correcting.
What is at stake for the Arc's tradition?
For Magnier and his allies, however, the issue is not about entertainment but about identity. The Arc is not merely a spectacle; it is a vital link in the chain that connects racing to breeding, and breeding to the long-term health of the thoroughbred. Coolmore, which has been involved in the ownership of four previous Arc winners, Montjeu in 1999, Hurricane Run in 2005, Dylan Thomas in 2007 and Found in 2016, knows this better than most. To open the race to geldings, they argue, would be to sever that link and reduce the Arc to just another handicap.
The coming weeks will be crucial. Will France Galop listen to the voices of tradition, or will it press ahead with a change that many believe will fundamentally alter the character of the race? One thing is certain: the battle for the soul of the Arc has only just begun, and the British and Irish racing community, with Coolmore at its head, is not about to surrender without a fight.
Frequently asked questions
Why are geldings currently banned from the Prix de l'Arc de Triomphe?
The Arc has traditionally been restricted to entire colts and fillies because of its importance to the breeding industry. Winners of the race are highly sought after as stallions, and the race is seen as a key indicator of future breeding potential.
What would change if the proposal goes ahead?
From next year, geldings would be permitted to run in the Arc, opening the race to a wider pool of horses. Supporters argue this would increase competition and excitement, while opponents fear it would diminish the race's prestige and its role in breeding.
Who is John Magnier?
John Magnier is the head of Coolmore, the world's largest thoroughbred breeding operation, based in Ireland. He is one of the most influential figures in global racing and has owned four Arc winners.
