Aintree Grand National Festival Day 1 preview: Corbetts Cross to challenge Shiskin and Geri Colombe

Emmet Mullins' Corbetts Cross is bidding for an Cheltenham-Aintree double as he prepares to contest the William Hill Bowl Chase on the opening day of the Grand National meeting on Thursday.

The chestnut was a wide-margin winner at the Cheltenham Festival, taking the Maureen Mullins National Hunt Challenge Cup, named after his late grandmother, by 17 lengths under Derek O’Connor.

That run proved his stamina and his ability in heavy ground, and now his class will be tested as he steps down in trip from three miles and six furlongs to three miles and a furlong at Aintree.

Frank Berry, racing manager to owner JP McManus, said: "He’s probably in at the deep end, but he’s in good form, came out of Cheltenham very well and Emmet was keen enough to have a crack at it.

"The other horse is in the three-mile novice, Inothewayurthinkin, so we said we’d give Corbetts Cross a crack at this and see how we get on.

"He’s obviously coming back from Cheltenham where he had a hard enough race and he is in at the deep end, but as long as he runs well and gets round we’ll be happy."

Nicky Henderson’s Shishkin is the reigning champion in the race but has met with mixed fortunes this year, refusing to race in the 1965 Chase at Ascot and then falling with the race at his mercy in the King George VI Chase.

He bounced back to stroll to victory in the Denman Chase but his participation in the Gold Cup was prevented by an unsatisfactory scope ahead of the race during a difficult time for the Seven Barrows stable.

"We had to miss the Gold Cup but there was nothing else you could do, it just hasn’t been his year.

"The King George, you could argue
