Dubai Millennium began his three-year-old season at Doncaster in May, where he was "impressive" in leading from the start and winning by nine lengths. On his next start, he was moved up in class and distance for the Listed Predominate Stakes over a mile and a quarter at Goodwood, a recognised trial for the Derby. Accompanied by a large Godolphin entourage and looking "magnificent", he started at odds of 4/11. In the race, he moved to take the lead two furlongs from home and went clear to win by three and a half lengths. Immediately afterwards, his connections expressed no worries about the Derby distance, although some concern was expressed about the possibility of firm ground, which was felt to be unsuitable for such a big, heavily built horse.
