Unbeaten Prix de l’Arc de Triomphe victor Ace Impact has been retired to stud.

Trained by Jean-Claude Rouget, the three-year-old has enjoyed an exemplary campaign, rising through the ranks from a Cagnes-Sur-Mer all-weather win in January to an electrifying length-and-three-quarters victory in the ParisLongchamp showpiece at the start of this month.

After his initial win in January, Rouget bided his time until sending Ace Impact for a conditions win in April, with a Listed success coming the following month.

Upped to Group One level for the Prix du Jockey Club after that, the son of Cracksman showed his trademark turn of foot to win the French equivalent of the Derby by three and a half lengths from Big Rock.

A Group Two victor in the Prix Guillaume d’Ornano at Deauville in August, Ace Impact was a short-priced Arc favourite and he justified that confidence with a stylish success under Cristian Demuro.

Owned in partnership by Serge Stempniak and the Chehboub family’s Gousserie Racing, connections had considered a possible Japan Cup bid or even campaigning on in 2024, but eventually opted to retire their star to stand at Haras de Beaumont stud in Normandy.

Ace Impact bows out the winner of each of his six career starts, boasting a rating of 128 which puts him just 1lb behind top Japanese runner Equinox.

“The way he races and his acceleration is very rare in a racehorse,” said Rouget.

“Very few racehorses are able to accelerate like that and for me (2008 Arc winner) Zarkava was a super champion and maybe had the superior acceleration, but he is not far from that.

“He gave me a great day when winning the Arc and also the Prix du Jockey Club and all the races were delicious. We started very slowly and then progressed to Listed, Group One and Group Two and then another Group One.

“We had very good days with Almanzor in the Prix du Jockey Club and Sottsass in the Jockey Club and the Arc and (they) were equally good champions. With Ace Impact his acceleration is stronger and with him, in three steps, the race is over.”

On his overriding memories of Ace Impact and the opportunity to train his progeny in the future, the handler added: “We have a few years to wait and we will try to find another one like him.

“We are champion trainer for the fifth time in France thanks to Ace Impact.

“My memory of him will be he is he is not impressive in the morning, but when racing, he is another horse with very strong acceleration.”

Jean-Claude Rouget is in confident mood ahead of Ace Impact’s bid for glory in the Qatar Prix de l’Arc de Triomphe on Sunday.

It has been quite the rise through the ranks for the son of Cracksman, who did not see the racecourse as a two-year-old and made his debut in the low-key surroundings of Cagnes-Sur-Mer in late January.

Another understated success at Bordeaux followed and he has since proved his class by landing a Listed race and the French Derby at Chantilly, before adding the Group Two Prix Guillaume d’Ornano to his tally at Deauville in the summer.

Ace Impact is the clear favourite to provide his trainer with a second Arc win following the success of Sottsass three years ago and while taking nothing for granted, Rouget feels there are no negatives.

“Why shouldn’t I be optimistic? I’m coming in with a horse that’s unbeaten,” he said on Tuesday.

“We know in any race anything can happen and we’re coming to the end of the season, but he gets three kilos from the older horses, which is important.

“I’m optimistic in the sense that he goes into the race unbeaten and has done everything we have asked him to so far.”

Following his mid-August triumph at Deauville, Rouget considered running his star colt in the Irish Champion Stakes at Leopardstown the following month, while he also had the option of getting a first taste of ParisLongchamp in the Prix Niel.

However, mindful of the fact Ace Impact had been on the go since the beginning of the year, he elected to keep his powder dry for the day that matters most.

Rouget added: “It’s very important that he stays a fresh horse because he started his season very early, which is not the usual start for a Classic horse.

“I didn’t want to run him last year in November, I wanted to wait and he then ran in January, so after he ran in Deauville I preferred to not run him again so that he has some freshness going into the Arc.

“It’s been six weeks (since Deauville) and the six weeks have passed very quickly.”

Ace Impact will be racing over a mile and a half for the first time this weekend, but Rouget does not expect him to be beaten for a lack of stamina, while the fact he has never run on the track is also not a concern for the trainer.

“Obviously we can’t be certain, but with the way he finishes his races and also the fact his sire was a winner over the distance gives us hope that he can stay,” he continued.

“If the Prix du Jockey Club (French Derby) had been over a mile and a half, as it was in the past, he would have won that.

“Last year Vadeni was in the same place for us and he ran really well (finished second to Alpinista).

“It is very rare I run a horse in the Grand Prix de Paris and after that there was just the Prix Niel, which didn’t hold any interest for me.

“I’m not worried about the course, he’s an easy horse once he’s settled in his race and there are plenty of horses that have won the Arc that also hadn’t run at Longchamp before.

“There was just no opportunity to do so, but it’s not something that bothers me.”

With the weather set fair in Paris for the rest of the week, underfoot conditions look likely to be quicker than is often the case for Europe’s premier middle-distance contest.

Rouget is therefore expecting there to be no excuses on the ground front, adding: “I think it is going to be good for everyone, which is an interesting point about this year’s race.

“In the past the race was often criticised for its heavy ground and the fact horses are tired, but this year I think the ground is going to suit everyone.”

Ace Impact and Hukum are among 15 horses to stand their ground for the the Prix de l’Arc de Triomphe at ParisLongchamp on Sunday following the first forfeit stage.

French Derby hero Ace Impact is the clear favourite to provide trainer Jean-Claude Rouget with his second victory in Europe’s premier middle-distance contest, following the success of Sottsass three years ago, but looks set to face a strong challenge from across the Channel.

The Owen Burrows-trained Hukum and Ralph Beckett’s Westover look the pick of the British contingent, with both having been kept fresh since their titanic tussle in the King George at Ascot in July.

Sir Michael Stoute’s Bay Bridge and John and Thady Gosden’s Free Wind, the potential final Arc ride for Frankie Dettori, also remain in contention.

Aidan O’Brien has left in Emily Dickinson, but on Sunday indicated she is likely to head for the Prix du Cadran instead, paving the way for his St Leger hero Continuous to be supplemented on Wednesday.

Irish hopes could also be carried by Sprewell from Jessica Harrington’s yard.

Other contenders for the home team include Pascal Bary’s Grand Prix de Paris hero Feed The Flame, last seen finishing second in the Prix Niel, and Simca Mille from Stephane Wattel’s yard.

The latter has won twice and finished second twice from four visits to the track and was last seen breaking his Group One duck in the Grosser Preis von Berlin at Hoppegarten in August.

Wattel said: “I have to say everything is fine, he’s in good shape and he has done some nice work. We are expecting good ground, which is important for him, and really I am happy with his condition.

“I don’t think we will have heavy ground and that would have been a reason not to run.

“I am really happy to have a runner in the Arc, not a first (top) chance but a fair chance to run well, which is exciting for us as a stable.

“He loves Longchamp and has always run very well there, which gives us a little more expectation than if we were running in England.

“I know the quality of the English horses and I know the quality of the two three-year-old French horses (Ace Impact and Feed The Flame), but our horse is running on his best racetrack and hopefully his best ground, so that gives us a little more chance.”

The German pair of Sisfahan and Mr Hollywood (Henk Grewe), Japan’s Through Seven Seas (Tomohito Ozeki), Haya Zark (Adrien Fouassier), Onesto (Fabrice Chappet) and Place Du Carrousel (Andre Fabre) are the others in the mix.

Jean-Claude Rouget’s Ace Impact extended his unbeaten record with a brilliant performance to land the Qatar Prix du Jockey Club at Chantilly.

Having completed a hat-trick on his previous run over 10 furlongs at this track last month, he gained a fourth success in scintillating fashion, coming from well off the pace in the hands of Cristian Demuro to collar long-time leader and favourite Big Rock inside the final furlong.

The additional half-furlong certainly helped the son of Cracksman, as Ace Impact looked better the further he went.

British raider Epictetus, trained by John and Thady Gosden, held every chance turning in, but Frankie Dettori’s mount faded to finish fifth, while Aidan O’Brien’s Continuous was in third throughout, before failing to see out the final furlong, eventually finishing eighth of the 11 runners.
