Pride made amends for finishing second in the Prix de l'Arc de Triomphe with victory in the Emirates Airline Champion Stakes at Newmarket.
The six-year-old mare, trained in France by Alain de Royer-Dupre and ridden by Christophe Lemaire, won comfortably by three lengths.
The 7-2 shot, runner-up 12 months ago, came out on top from Rob Roy (20-1), with Hurricane Run, the 9-4 favourite, a head away in third. Derby winner Sir Percy finished unplaced.
With no natural front-runner or pacemaker in the field, Hurricane Run was sent into the lead by Mick Kinane, with Notnowcato and Sir Percy, tracked by Pride, close up.
There was little change in the order until the Dip when Pride made her move on the stands side.
Hitting the front at the furlong marker, she galloped on strongly up the hill to run out a convincing winner.
