Nick Luck and the Channel 4 Racing team are at Haydock Park with the Lancashire track's biggest day of the flat season. The feature race is the ú260,000 Sprint Cup which was first run 50 years ago. Back to back wins have only been recorded once in the race's history with Sir Peter O'Sullevan's Be Friendly taking the first two runnings, but now Henry Candy's Twilight Son looks to repeat the feat. Haydock Park: 3.00, 3.30, 4.00 and 4.30pm. Ascot: 2.40 and 3.10pm: Kempton Park: 3.45 and 4.15pm.
