Impaire Et Passe had to survive a lengthy stewards’ inquiry before being declared the winner of the William Hill Aintree Hurdle.

Willie Mullins’ evens favourite rounded the final bend on the bridle but did not run straight to the line as both Langer Dan and Bob Olinger threw down their challenges in what was a thrilling finish to the Grade One contest.

Impaire Et Passe appeared to cross Langer Dan’s path after the last, while Bob Olinger also seemed to drift inwards on the run to the line, leaving Langer Dan sandwiched between them.

The judge was required to split the trio as they crossed the line, with Impaire Et Passe coming home a nose in front of Bob Olinger, with Langer Dan a further short head back in third,

A stewards’ inquiry was soon called, but Impaire Et Passe was eventually confirmed the victor.

Daryl Jacob is extremely excited to be given the opportunity to ride Impaire Et Passe in the Matheson Hurdle at Leopardstown on Friday.

Only four are due to go to post in the two-mile Grade One, and three of those are trained by Willie Mullins.

It is an event Mullins has farmed in recent years – since 2010 he has won all bar three renewals, with Hurricane Fly and Sharjah winning four apiece.

Last year the champion trainer was successful with State Man and he lines up once more as the choice of Paul Townend.

That meant the ride on last year’s hugely impressive Ballymore Novices’ Hurdle winner Impaire Et Passe was free and as retained rider to owners Simon Munir and Isaac Souede in the UK, Jacob was in pole position.

Impaire Et Passe lost his unbeaten record on his seasonal return in the Hatton’s Grace, and Mullins has taken the decision to drop him in trip to two miles. But Jacob feels the testing ground will make it more of a stamina test.

“I’m very much looking forward to riding him. He’s a very exciting horse for Simon and Isaac and everyone and this is another step on the ladder for him,” said Jacob.

“He’s racing over two miles for the first time in a while, but I’ve been in Ireland all week and there has been a lot of rain.

“The hurdle course on Wednesday went soft then heavy, but he has handled that sort of ground, he’s won over further and he has got speed.

“He’s a hugely exciting horse and I’m very grateful for the opportunity, I can’t wait to ride him.

“I rode him out on Thursday morning, he seems in really good form and I really don’t see the ground being an issue at all.”

Jacob has enjoyed a particularly fruitful spell of late and is operating at a strike-rate of over 40 per cent for the past two weeks, and he would love to top it off with a Grade One.

“I’ve had a nice few winners of late, but a Grade One win before the new year would be lovely,” he said.

Understandably given his choice, Townend feels State Man sets the standard given the only horse who has finished in front of him when he has completed since joining Mullins is Constitution Hill.

He told his Ladbrokes blog: “He seems to set the standard this side of the water. His only defeat was by Constitution Hill last year. It’s interesting he’s being taken on by Impaire Et Passe.

“I thought Impaire Et Passe ran with a lot of credit in the Hatton’s Grace in Fairyhouse. He has a run under his belt and State Man won the Morgiana.

“It’s a big test, but State Man played at the top table all last season and sets the standard. The pair are sure to make a good race of it.”

Mullins also runs the mare Echoes In Rain, while Gordon Elliott’s Fils D’oudairies is the only other contender.

Connections of Impaire Et Passe insist there were “a lot of positives” to take from his comeback defeat in the Hatton’s Grace Hurdle at Fairyhouse.

The Willie Mullins-trained five-year-old was one of the star novices of last season, carrying the ‘double green’ colours of owners Simon Munir and Isaac Souede to four victories, including Grade One triumphs at the Cheltenham and Punchestown festivals.

With some bookmakers rating him as the biggest threat to Constitution Hill for the Champion Hurdle this term, Impaire Et Passe was odds-on to pick up where he left off on Sunday, but after travelling strongly in the hands of Paul Townend, he was mowed down by the defending champion Teahupoo.

While disappointed to suffer defeat, the owners’ racing manager Anthony Bromley is keeping the faith.

“I was perfectly happy with Impaire’s return, he took a good blow and just got done close home. I think he showed plenty and we’ll look forward to the season ahead,” he said.

“It was his first step outside of novice company and I think he performed with a lot of credit. He’s such a lovely horse and there were a lot of positives to take from the run.”

What route Impaire Et Passe takes to the Champion Hurdle at Cheltenham remains undecided, with Mullins also responsible for another major player in the form of State Man.

The latter won the Morgiana Hurdle, the Matheson Hurdle, the Irish Champion Hurdle and the Punchestown Champion Hurdle last term, with his only defeat coming at the hands of Constitution Hill when runner-up at Prestbury Park.

State Man made a successful reappearance when registering back-to-back wins in the Morgiana last month, and Bromley believes there is every chance Impaire Et Passe will meet his stablemate at some stage before Cheltenham in March.

He added: “Whether he comes out again at Christmas or waits for the Dublin Racing Festival (Irish Champion Hurdle), we’ll just wait and see what Willie wants to do.

“I’d imagine he’s going to come back to two miles now because there’s isn’t a two-and-a-half-mile race at Christmas in Ireland – it’s either two miles or three miles.

“Whether or not he does run in the Matheson Hurdle will be Willie’s decision as he’d obviously be taking on State Man, but if he doesn’t take him on at Christmas he’d be taking him on at the Dublin Festival and that will tell us more as to where we are with the horse.

“There aren’t the races in Ireland to split them up, the only time you could was for their reappearance runs as one could go Morgiana and one could go Hatton’s Grace.

“From now on they’ll have to meet and then, come March, there’s another one for us to meet (Constitution Hill)!”

A possible alternative to locking horns with State Man over the festive period would be to make the trip to Britain for an early clash with Constitution Hill in the Christmas Hurdle on Boxing Day, but that appears highly unlikely, with Bromley saying a trip to Kempton was of “no interest at all”.

Teahupoo proved too game for hot favourite Impaire Et Passe as he completed back-to-back wins in the Bar One Racing Hatton’s Grace Hurdle at Fairyhouse.

Gordon Elliott’s charge ended the long unbeaten run of Honeysuckle in the Grade One contest last year and this time it was Willie Mullins’ Impaire Et Passe who had his bubble burst.

Sent off the 4-5 favourite, Impaire Et Passe was looking to pick up where he left off last term with top-level successes at both the Cheltenham and Punchestown Festivals and he appeared to be travelling supremely well as they turned for home.

Pacemaker Zanahiyr dropped out in the straight, leaving Paul Townend to go for home on the market leader – but Teahupoo had other ideas.

The pair were neck and neck on the approach to the final flight but it was Teahupoo who kept finding for pressure on the run to the line, with Jack Kennedy’s mount registering a length success at odds of 85-40.

Teahupoo finished a close third in the Stayers’ Hurdle at Cheltenham last term and Betfair go 4-1 from 6s about him for that race, while Impaire Et Passe is out to 8-1 from 11-2 for the Champion Hurdle following the first defeat of his career.

Connections of Impaire Et Passe are keen to have a crack at the Champion Hurdle despite the imposing figure of Constitution Hill standing in their way.

Trained by Willie Mullins and owned by Simon Munir and Isaac Souede, Impaire Et Passe looked imperious in winning all four outings last term.

While his six-and-a-half-length victory over stablemate Gaelic Warrior in the Ballymore Novices’ Hurdle last season was impressive, he is a best-priced 13-2 for the Champion Hurdle, with current title-holder Constitution Hill the general 4-9 favourite after his connections ruled out a chasing switch.

“Impaire Et Passe is staying hurdling. Connections are keen to have a crack at the Champion Hurdle,” said Mullins.

“I’m not sure if that decision was made before the Constitution Hill one or not, but I think he has a fair crack at the Champion Hurdle.

“He won the Ballymore, the only reason he ran in that was because we had Facile Vega in the Supreme, so that is the route he will go down.

“If he improves any little bit – he’ll probably have to improve a fair bit to beat Constitution Hill – but I think he can and that is the decision we’ve made. I think he might start in the Hatton’s Grace.”

Second to Constitution Hill last season was Mullins’ State Man. He won all his other four outings at Grade One level but has nine lengths to find with Nicky Henderson’s supreme talent.

“I think when you can win four Grade Ones in Ireland – every horse is only one gallop away from an injury – it’s all to play for. Constitution Hill has to get there and so do we, so we just felt that he could earn his keep easier over hurdles, that was the main reason (for staying over hurdles),” said Mullins.

“The obvious race is the Morgiana. It’s hard to see him beating Constitution Hill, but I’m hoping he’ll improve.

“The two of them will get entries in both the Morgiana and Hatton’s Grace, the two could run in either, it will depend on who is ready first. Whoever runs in the Morgiana, we might let the other go for the Hatton’s Grace.”

Some bookmakers have Mullins’ Triumph Hurdle winner Lossiemouth in the Champion Hurdle betting but she is likely to stick to her own sex.

“Lossiemouth could go for the Champion Hurdle or the Mares’ Hurdle but it will more than likely be the Mares’ Hurdle,” said Mullins.

“I haven’t decided where I will start her yet as she had a busy enough season last season, she’s only four. We’d probably like to run her at Christmas, Dublin Festival and Cheltenham so whether she runs before Christmas, I’ve not decided and might just keep her fresh.”

Connections of Impaire Et Passe insist a potential clash with Constitution Hill was not a factor in their decision to keep last season’s star novice hurdler over the smaller obstacles this term.

There were differing views on Tuesday after Nicky Henderson confirmed his Champion Hurdle hero Constitution Hill would not be embarking on a chasing career in the immediate future, with some bemoaning the decision due to the perceived lack of depth in the two-mile hurdling division.

In Impaire Et Passe, though, he could face a new and significant rival, with the five-year-old having won each of four starts since joining Willie Mullins, including a dominant success in the Ballymore Novices’ Hurdle at the Cheltenham Festival in March.

Given the irresistible force that stands in their way, many expected Impaire Et Passe’s owners Simon Munir and Isaac Souede to elect to send their charge over fences in the autumn – but he will indeed head down the Champion Hurdle route, regardless of the opposition.

The owners’ racing manager, Anthony Bromley, said: “Basically it was always the thinking all summer that Impaire Et Passe was pretty inexperienced and another season hurdling would be good for the horse.

“We weren’t making the decision based on what other horses were around us, we were making the decision based on what was the best decision for the horse and his long-term career.

“You never know what will happen to all these horses, so you make the decision based on what’s best for the actual animal rather than what’s around you, that was the thinking really.”

While the chances of Constitution Hill going chasing in the future appear slim, Impaire Et Passe is expected to switch disciplines next term.

Bromley added: “He’s so lightly raced that another season hurdling will hopefully toughen him up and then we can go chasing next season.

“He is the stamp of a chaser so he is exciting for that job, but we’ll see how high he can go over hurdles first.”
