Nicky Henderson has few concerns about the cold week ahead as Constitution Hill’s eagerly-awaited return in the BetMGM Fighting Fifth Hurdle draws ever closer.

Having made the decision to stay over the smaller obstacles, the Seven Barrows superstar has long had the trip to Newcastle to defend his Fighting Fifth crown inked on his calendar.

The dry weather last autumn meant Constitution Hill was rerouted from Ascot to Gosforth Park for his seasonal debut 12 months ago, but Henderson does not envisage any similar problems this time around despite temperatures set to fall over the coming seven days.

And having completed his big-race preparations at his Lambourn home earlier this week, Henderson reports his Champion Hurdler to be in rude health ahead of the first step on his journey back to the Cheltenham Festival.

“He galloped yesterday and everyone watched him and he’s fine,” said Henderson, speaking at Ascot, where he suffered the disappointment of Shishkin refusing to start in the 1965 Chase.

“All his work is done, it finished yesterday.

“I would seriously hope with a Grade One like that (there will be no issues), Newcastle will be fine. I’m not worried.

“He’s 100 per cent. He’s in very good form.”
