Prix Vermeille
On her final appearance of the season, Circus Plume was set to France for the Prix Vermeille at Longchamp Racecourse in September. She tracked the pacemakers before taking the lead in the straight, at which point the race devolved into a match between Circus Plume and the French filly Northern Trick. Circus Plume finished second, a length behind Northern Trick and three lengths clear of the other runners.
