Nico De Boinville: No room for error with Constitution Hill

Nico de Boinville knows Constitution Hill's electrifying jumping leaves "no margin for error" – particularly in the white-hot cauldron of the Unibet Champion Hurdle.

Nicky Henderson’s star is chasing a second successive win in the race having demolished State Man by nine lengths last year.

There are those who feel State Man has enjoyed a better preparation this term, and he has won four Grade Ones since that reverse while Constitution Hill has only been seen once since April.

However, De Boinville has full faith that Henderson is the right man for getting a horse to peak on the big day.

"I couldn’t have been happier with him at Kempton. State Man has gone and done what he does on that side of the Irish Sea, but there are still four weeks to go and you are just keeping all fingers crossed," De Boinville said.

"I’ve been going there before with the likes of Altior and at the last minute things go wrong, so you are just hoping everything goes right and we have a very good prep."

Regarding his mount’s incredible jumping technique he went on: "You really do feel like there’s no margin for error because you are going so fast, you are literally just clipping the top bar. You are going very, very quick and there will be no exception in the Champion Hurdle, it’s going to be run at a very good pace and hopefully the right horse wins.

"He’s (Henderson) definitely not one to doubt. If the weather hadn’t stopped us, he would have had two runs and no one would be saying anything as he’d have gone to the Fighting Fifth and Christmas Hurdle, so ultimately we were stopped because of the weather.

"Hopefully he’ll be busy enough in the spring, you can go to Aintree and Punchestown after Cheltenham if he comes through it well."
