Of the five Thoroughbred Group 1 winners on Sunday’s Prix de l’Arc de Triomphe (G1) undercard at ParisLongchamp, Friendly Soul and Ramatuelle are the likeliest to proceed to the Breeders’ Cup.

Juddmonte’s homebred Bluestocking crowned her season in Sunday’s $5.5 million Prix de l’Arc de Triomphe (G1), giving the late Khalid Abdullah’s operation a record-setting seventh victory in Europe’s fall championship.

On top of the loaded Breeders’ Cup prep weekend stateside, five more “Win and You’re In” events are set for ParisLongchamp on Sunday.

Opera Singer stole the show on the undercard with a five-length conquest of the Prix Marcel Boussac. So devastating was the Aidan O’Brien pupil that the ever-reticent jockey Ryan Moore was already talking up her chances in the 2024 Arc.

Deploying the same lethal acceleration that carried him to a record-breaking victory in the Prix du Jockey Club (French Derby) (G1), Ace Impact overwhelmed the field in Sunday’s Prix de l’Arc de Triomphe (G1) at ParisLongchamp.

Alpinista extended her winning streak to eight in Sunday’s Prix de l’Arc de Triomphe (G1), driving through the very soft going to defeat Vadeni and defending champion Torquator Tasso at ParisLongchamp.

In addition to Alpinista in the main event, British-trained horses captured two other Group 1s on Arc Day, and the French turned their own Group 1 triple in Breeders’ Cup Challenge races.

The marquee event among six Group 1s for Thoroughbreds at ParisLongchamp, the Arc is one of five Breeders’ Cup “Win and You’re In” races on the superb card.

For only the third time in 100 runnings, Germany has captured the Prix de l’Arc de Triomphe. German Horse of the Year Torquator Tasso, overlooked at 71-1, snatched Sunday’s centennial edition.

With the heavy going likely playing a role in the results, favorites were beaten in four other Breeders’ Cup “Win and You’re In” events on Arc Day.

Breeders’ Cup Turf (G1) winner Tarnawa will tackle three-year-old stars Adayar, Hurricane Lane, and Snowfall, with added intrigue courtesy of Japan’s Chrono Genesis and Deep Bond.
