Derby winner Workforce wins Prix de l'Arc de Triomphe
Replay - Workforce wins thrilling Arc
Derby winner Workforce followed up with victory at Longchamp in the Prix de l'Arc de Triomphe for English trainer Sir Michael Stoute and Ryan Moore.
Stoute had never won an Arc before but saw Moore hold off a surprise challenge from Japanese entry Nakayama Festa.
Sarafina finished strongly to take third, with favourite Behkabad fourth.
Earlier, the Freddie Head-trained Goldikova won a record 11th European Group One with victory in the Prix de la Foret under Oliver Peslier.
Fittingly, Miesque, the previous record-holder, had been ridden by Head.
Peslier positioned the five-year-old, who has won 13 of her 19 starts in all, on the rails early on. And any doubts she would be inconvenienced by the soft ground were put to bed as she held off the Richard Hannon-trained pair of Paco Boy and Dick Turpin.
Head said afterwards: "It's extraordinary. I was very scared about the going, it was touch and go whether she would run. Olivier rode a great race, now she will head to America for the Breeders' Cup Mile."
In the Arc, the most famous prize in French racing, Stoute had to withstand some post-race nerves as a stewards' inquiry was announced.
But it was soon clear that Workforce, given an assured ride from champion jockey Moore, was not involved in their deliberations, allowing the Newmarket-based veteran a chance to celebrate his maiden success in the Arc.
It was announced some time later that the horse finishing seventh, Planteur, had been disqualified for interference.
Workforce travelled strongly throughout but was nearer last than first on the turn for home - until showing an excellent turn of foot in testing conditions to hit the front approaching the final furlong.
But Nakayama Festa, barely mentioned in pre-race deliberations, gave Moore concern all the way to the finish, with the fast-finishing French filly Sarafina taking third-place prize money.
Workforce, a brilliant winner at Epsom where he broke the course record, was not confirmed as an Arc participant until Thursday following his dismal performance in the King George VI and Queen Elizabeth Stakes at Ascot on his previous start.
Stoute said: "He was a big disappointment in the King George. It's been a real team effort [to get him back] and I'm not just saying that as a cliche.
Jockey and trainer praise Workforce
"The jockey gave him some ride. He got a nice run through, it got a bit tight at the top of the false straight but there was half a gap there and he was very brave and really quickened into it well.
"If you have any ambition when you start training, you want to win the Arc.
"We have had a lot of horses running particularly well in it without doing it, so I'm thrilled, especially as he was so impressive on Derby day and the King George performance was inexplicable.
"Ryan felt he should have just switched him off more and I think I may have trained him too hard for the race. I said that to Prince Khalid [Abdullah, owner] afterwards so I think I was proved right on that.
"I don't know if I'm likely to train him as a four-year-old but I'd love to."
The other leading British-trained hope, Youmzain, had finished runner-up in the last three renewals of the race but never threatened to land a blow this time.
His trainer Mick Channon said: "There were no real excuses, although he didn't travel as well as he normally does.
"I'm disappointed, but not with the horse, as he's given it everything in this race over the last four years.
Behkabad's trainer Jean-Claude Rouget felt he had reason to be a little hard done by, reporting: "He had a wall of horses in front of him at 400m and was blocked."
And Aidan O'Brien said of Coolmore hope Fame And Glory (fifth): "He was coming to challenge and then he got mullered."
