Nicky Henderson is unconcerned about the lack of a recent run for Constitution Hill ahead of his bid for back-to-back victories in the Ladbrokes Christmas Hurdle.

On what Henderson sees as the first day of a “new term” for his star pupil, he will belatedly get his season under way at Kempton on Boxing Day, with the weather having scuppered an intended defence of the Fighting Fifth at Newcastle.

The Seven Barrows trainer flirted with the idea of running the six-year-old in a rescheduled Fighting Fifth at Sandown seven days later, but ultimately branded the prospect of running in heavy ground just over a fortnight before his festive target as “physically not possible”.

“That (Newcastle) was the original plan and that is where he would have been, and we would have been on the same leg as last year. Unfortunately, we are not,” said Henderson.

“He was ready for Newcastle, and he is ready for Kempton. He is big and well and strong, he came in looking very well. At one stage I was a bit behind as he was so big.

“It took a bit longer to get the shape back into him, but that is long gone. He has had to do a bit more work as it is all very easy to him. His schooling is unbelievable.

“As we have always said, his temperament is such that it (journey to Newcastle) wouldn’t make any difference to him and he’s had an away day.

“If he comes through this and it goes like last year I’d be confident about the next bit. But the first day out of the year is crucial, it’s like a first day at school. He’s been good at home, but there are new kids on the block and he’s starting a new term.

“He has got to be as good as he ever was at Kempton, then we can look forward.”

With the privilege of training a horse of Constitution Hill’s stature comes no little amount of pressure, but it is something Henderson embraces.

He added: “If you guys (press) didn’t want to talk to us or there was no pressure then it would be time to give up as you have nothing to talk about.

“Sprinter Sacre was in this position when he was at his best. When he was in his first innings and at his absolute pomp, he was seriously unbeatable.”

Constitution Hill will be extremely cramped odds to dispatch of his Kempton rivals, with the Paul Nicholls-trained Rubaud seemingly his biggest threat.

The five-year-old is unbeaten in his last four starts, having landed the Dovecote at Kempton, the Scottish Champion Hurdle at Ayr, a Listed prize at Kempton and the Elite Hurdle at Wincanton – but Nicholls is well aware his latest assignment is an extremely difficult one.

He told Betfair: “He is going to be an awesome chaser next season, but his form over hurdles is so progressive he deserves a shot at this Grade One prize.

“While he has won his last four starts I realise he probably faces an impossible task against Constitution Hill, but we are giving it a go and if he finishes second we will be delighted.”

Henderson has a second string to his bow in First Street, while Kerry Lee has declared both Nemean Lion and Black Poppy.

Alan King’s admirable veteran Sceau Royal completes the field.
