Found triumphs in O'Brien's Arc 1-2-3
The Prix de l'Arc de Triomphe has been a long-held dream for Found and the Aidan O'Brien-trained filly hit the jackpot on a never-to-be-forgotten afternoon for Ballydoyle at Chantilly.
In a script that could scarcely have been written, Ryan Moore's mount atoned for her unlucky-in-running ninth to Golden Horn 12 months ago as she led home an O'Brien one-two-three from stablemates Highland Reel and Order Of St George.
Roger Varian's hot favourite Postponed could only manage fifth place, while Dermot Weld's dual Derby hero Harzand was ninth.
O'Brien said: "We've had our eye on this for a long time.
"When Ryan rode her as a two-year-old and said that she could win an Arc - he was obviously right.
"It's a great feeling to saddle the first three home in an Arc, there's not much to beat it, but it's all down to a fantastic team effort and I'm delighted for John (Magnier), Michael (Tabor), Derrick (Smith) and their families."
First blood on the big day had gone to Britain with Charlie Appleby's Wuheida impressing in the Prix Marcel Boussac to assume favouritism for the 1000 Guineas and Oaks.
Appleby said: "She saw out that trip well, and I've always thought of her as an Oaks filly."
James Fanshawe does remarkably well on his trips to France and it was a second Group One across the Channel for Speedy Boarding and the Newmarket trainer as she floored Pleascach and So Mi Dar in the Prix de l'Opera.
It was another for Britain in the Prix de l'Abbaye, as Luke Morris timed it to perfection on Sir Mark Prescott's Marsha.
Morris said: "The boss had freshened her up for this, we've always had high hopes for her and this is the icing on the cake."
Nunthorpe heroine Mecca's Angel was third, with trained Michael Dods saying he will give his pride and joy a week to recover before thinking about the British Champions Sprint at Ascot on October 15.
Proceedings were complete when Harry Bentley steered Henry Candy's Limato to a most impressive victory in the Prix de la Foret.
