The Longines Breeders’ Cup Classic is a marquee race each autumn, headlining the Breeders’ Cup World Championships which are held this year at Santa Anita Park. This year’s race is Nov. 2 and is full of intrigue including a mare taking on the boys, 3-year-olds eager to prove their form against older foes, and handicap stalwarts aiming for the biggest prize of their careers.
