Sky Sports Racing ambassador Hollie Doyle previews four major handicaps at Ascot on Saturday, live on Sky Sports Racing, along with the feature events at Haydock and Kempton.

Almeraq is on a retrieval mission after flopping in the July Cup, but he can clinch his second Group 1 of the season in the Betfair Sprint Cup (3.40) at Haydock Park on Saturday. A combination of the fast ground on an undulating track may have been his downfall at Newmarket, but Doyle's husband Tom Marquand reports his mount fresh and well for an assignment he should relish. Shadwell's colt came of age in the Queen Elizabeth II Jubilee Stakes at Royal Ascot and has proven form on soft ground, which Doyle expects will bring out the best in him.

Clive Cox's Coppull looked a colt going places when stepping up to seven furlongs to win the Hungerford Stakes at Newbury and arrives at Haydock in rude health. He's a Group 1 winner in waiting but has never encountered soft ground before, raising a question mark if he takes his chance. The step up to seven furlongs is ideal for another William Haggas horse, Thunder Call, who reappears in the Schweppes Handicap (1.40) at Ascot on Saturday. He was doing his best work in the closing stages of the Shergar Cup Sprint at this track last month and remains well treated off 93 to capitalise under Cieren Fallon.

Heyzoom has been gelded since finishing a creditable fourth to St Leger fancy Enceladus in the King George V Stakes at the Royal Meeting and looks sure to go well in the Tote.co.uk Money Back 2nd Handicap (2.10) at Ascot. However, Owen Burrows' three-year-old faces a formidable opponent in Decade Of Time, who has been in great form this year and has been crying out for the step up to this 12-furlong trip. Since winning his novice, Jack Channon's colt has produced two solid runs in 10-furlong handicaps at Newmarket and Goodwood, and won't be troubled if the rain comes.
