Prix Hocquart
On his three-year-old debut Adelaide travelled to France for the Prix Hocquart at Longchamp. He finished half a length behind Free Port Lux but beat eventual Grand Prix de Paris winner Gallante into third place. He returned to Ireland to win the Group 3 Gallinule Stakes being ridden by regular Ballydole Jockey Joseph O'Brien for the first time. A month later Adelaide started the favourite for the King Edward VII Stakes at Royal Ascot but finished second place behind Eagle Top.
