There were four other Group 1 contests on the undercard of the Prix de l'Arc de Triomphe at Longchamp in Paris. The distaff equivalent of the Arc is the €250,000 (about $345,000 U.S.) Qatar Petroleum Prix de l'Opera (G1), featuring a field of 14 older fillies and mares going 2000 meters. 58-1 Lady Gloria set the early pace while being stalked by 7-2 Treat Gently. Turning for home, Lady Gloria continued to lead but tired and dropped from contention at the 3/16 pole. 2-1 favorite Lush Lashes, who was up close to the pace early, moved up along the rail to take the lead at the 1/8 pole, but 12-1 Lady Marian, 8th at the top of the lane, swung out wide for room and closed with a rush to win going away by 1 1/2 lengths in 2:03.80. It was another 1 1/2 lengths back from Lush Lashes to 9-2 Katiyra third.
