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.

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.

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.

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.

Bracketing Sunday’s Prix de l’Arc de Triomphe (G1) are four additional Breeders’ Cup “Win and You’re In” races.
