The Aga Khan Studs ruled ParisLongchamp's Arc Trials Day, with the king of them all Daryz (Sea The Stars) completing a high-profile treble with another tour de force in the G2 Qatar Prix Foy.Treating the Coronation Cup winner Bay City Roller (New Bay) like a lead horse, the reigning Arc hero took that rival's measure inside the final furlong with Mickael Barzalona sitting chilly and at the line the 1-5 favourite had a comfortable 1 3/4-length margin to spare.“I couldn't be happier with this as a trial,” Francis Graffard said. “He got a nice lead and he travelled really nicely, so it's the perfect prep for the Arc. I left plenty on him, so he should be spot-on for four weeks' time.”Roll on the Arc!
