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.

Star sophomore St Mark’s Basilica passed his first test versus elders in grand style in Saturday’s Eclipse S. (G1) at Sandown.

Day two of Royal Ascot has just the one Group 1 contest, but it’s a dandy. Wednesday’s Prince of Wales’s S. (G1), offering a free berth in the Breeders’ Cup Turf (G1), could pit champion filly Love against defending champion Lord North.
