Daryz produced a devastating display in the Paris sunshine to capture a second Qatar Prix de l’Arc de Triomphe and establish his place among flat racing’s greats.Only three colts have returned to defend their crown in the Arc since the end of the second world war, with none managing the feat since Alleged in 1978.However, Francis-Henri Graffard’s exceptional four-year-old eagerly grasped his moment in time on the Bois de Boulogne, delivering his trademark turn of foot in the Longchamp straight under Mickael Barzalona to run down the gallant Bay City Roller and score by a length-and-a-quarter.The victory took the winner’s course record to a remarkable eight victories from nine starts at the Paris venue, but hopes of seeing him trying to complete a record-breaking hat-trick next autumn were swiftly expunged with a stud career now awaiting the brilliant son of Sea The Stars.‘I was never worried,’ said owner Princess Zahra Aga Khan, who took over the racing operation of the Aga Khan Studs following the death of her father last year.‘He has such a will to win, and such speed, I was pretty relaxed. Daryz has won back-to-back Qatar Prix de l’Arc de Triomphe, cementing his place among the flat racing greats‘Last year was especially tough as I was caught up in the moment and still dealing with the loss.’Referring to her colt’s future, she added: ‘You get to the point where you’re taking a risk every time you run the horse.‘His mother improved with age but would we want him to train on for another year? I’m not sure. He has other things to do.’Whereas Daryz’s owner was fairly relaxed throughout, the brilliant Graffard admitted to plenty of pre-race nerves.‘I really felt the pressure for the last fortnight,’ he said.‘I tried to remain zen but it is difficult to do so and the weight on my shoulders was enormous when he went into the stalls before the race.‘But he is such a great champion that once he got a clear run I was more relaxed.’‘I am a trainer and I like to race, so I wish to try for a third time, but I don’t think I will be allowed. I think that would be too much pressure!‘I don’t think he has to prove anything else, it has been beautiful to watch and it was beautiful to watch a champion like him win a race like that.’For George Scott, trainer of Bay City Roller, defeat brought mixed emotions: ‘I could see Daryz coming. We came up second-best to an outstanding racehorse. Congratulations to the connections.‘I’m proud of our horse. He’ll go to the Champion Stakes now and hopefully we’ll get a little bit of rain.’Fellow UK raiders Friendly Soul, Kalpana and Maltese Cross were fourth, fifth and sixth respectively, but there was British Group 1 success on the card for Karl Burke and rider Jack Nicholls with Miss Yechance in the Prix de l’Abbaye, while John & Thady Gosden claimed the Prix de l’Opera courtesy of the Christophe Soumillon-ridden Miss Scott.
