Three Group 1 races and a Group 2, with prizemoney ranging from $1 million to $6 million, highlight a strong turf card on Dubai World Cup Day.

The latest additions to the Breeders’ Cup Challenge series, Saturday’s Champion S. (G1) and Queen Elizabeth II S. (G1) serve up terrific clashes that promise to be the highlights of British Champions Day at Ascot.

Royal Ascot’s glittering five-day stand begins Tuesday. Three Group 1s are on tap, beginning with the Queen Anne S. (G1) that serves as a “Win and You’re In” for the Breeders’ Cup Mile (G1), and a couple of American sprinters are taking on defending champ Battaash in the King’s Stand S. (G1).
