Trueshan showed his class to comfortably win the Group 1 Al Shaqab Goodwood Cup in the feature race of the opening day of the Glorious Goodwood festival.
It was the first win on flat for trainer Alan King and provided even more Group 1 glory for jockey Hollie Doyle, who becomes the first woman to ride a winner in the Goodwood Cup's 213-year history.
Stradivarius, who had been bidding for five consecutive successes in the race, was pulled out shortly before as a non-runner because of the ground, leaving Trueshan as the 6/5 favourite. Away He Goes came in at second (33/1), while Sir Ron Priestly (9/2) finished third in a field of eight runners.
"He's a superstar on this ground. They didn't go very quick early on and he was quite free which he can be but at halfway I just let him slide onto the girth of the leader and he dropped the bridle on me," Doyle said.
"The further I went the better and he's hit that rising ground and found another gear. All credit goes to Alan and the team.
"It's been in my mind every day since Champions Day about when we could get back together in a big race like this. These are the days you do it for."
