Trainer Aidan O’Brien picked up the 400th Group 1 win of his career when 2023 Breeders’ Cup Turf (G1) hero Augustin Rodin pounced to a determined triumph in the Prince of Wales’s (G1) at Royal Ascot.

Opera Singer stole the show on the undercard with a five-length conquest of the Prix Marcel Boussac. So devastating was the Aidan O’Brien pupil that the ever-reticent jockey Ryan Moore was already talking up her chances in the 2024 Arc.

In addition to Alpinista in the main event, British-trained horses captured two other Group 1s on Arc Day, and the French turned their own Group 1 triple in Breeders’ Cup Challenge races.
