Barry Connell remains at a loss to explain Marine Nationale’s disappointing performance in the Irish Arkle at Leopardstown on Saturday.

A brilliant winner of last season’s Supreme Novices’ Hurdle at the Cheltenham Festival, the seven-year-old made a foot-perfect start to his career over fences at Leopardstown’s Christmas meeting and was odds-on to add a third Grade One to his CV back at the Foxrock circuit.

However, while Marine Nationale briefly threatened to challenge rounding the home turn, he found little when push came to shove and was ultimately well beaten in fifth place.

Connell feels underfoot conditions may not have been ideal for his stable star, but will conduct further tests this week to try to discover if something else was amiss.

He said: “He seems fine this morning, but we’ll have to run a lot of further tests on him this week, so we won’t know until later in the week what the full clinical picture of him is.

“He’s sound anyway and seems to come out of the race OK, so we’re still a little bit in the dark.

“I’d say the ground definitely was harder going than it was at Christmas. They had no fresh ground, so it was probably tacky, holding ground, which wouldn’t be ideal.

“We just don’t know (what happened), but the horse had an off day and it won’t be until later in the week when we’ve finalised our checks on him.”

While Marine Nationale’s odds for the Arkle at Cheltenham next month obviously drifted in the aftermath of his defeat, he remains at the head of ante-post lists and Connell is hopeful he can show his true colours on his return to the Cotswolds.

He added: “Our intention is to just put a line through and head on to Cheltenham.

“He obviously showed a lot of speed in the Supreme last year, beating the winner from yesterday (Il Etait Temps) and Facile Vega (finished third on Saturday).

“Hopefully we’ll get spring ground at Cheltenham and he’s proven his liking for the track there.

“All these horses can get beat at some stage and unfortunately that was the case yesterday. We’ll just see if anything else emerges.”

Marine Nationale maintained his unbeaten record with a near foot-perfect display on his debut over fences at Leopardstown.

Owned and trained by Barry Connell, the six-year-old won each of his two bumper starts and was three from three over hurdles last season, culminating in a brilliant victory in the Supreme Novices’ Hurdle at the Cheltenham Festival in March.

Encountering larger obstacles for the first time, having sidestepped a potential engagement at Navan last month on account of testing conditions, Marine Nationale was a 1-2 shot for the Paddy Power From The Horses Mouth Podcast Beginners Chase and those who took the cramped odds will have had few concerns for the duration of the two-mile-one-furlong contest.

Michael O’Sullivan’s mount raced zestfully on the front end from the drop of the flag and was particularly impressive in the jumping department.

The market leader was still hard on the bridle turning for home and another bold leap at the final obstacle put the seal on a comfortable eight-and-a-half-length victory over Firm Footings.

Paddy Power and Betfair were suitably impressed by the winner’s performance, trimming his odds for the Arkle at Cheltenham to 4-5 from 7-4, while Coral are marginally bigger at evens.

“I didn’t enjoy watching it at all. Last year we were coming in under the radar and this year we are favourite for the Arkle and expected to win,” said Connell.

“It’s a horse race and anything can go wrong, but the way he jumped today he’s vindicated what we have seen from his schooling – he’s an absolute natural.

“He’s only three-quarters fit today and Michael said he gave a little bit of a blow. He was a little gassy early on, but you couldn’t ask for any more than that.

“The ground is described as soft, but there is a bottom to it. He goes on every ground, but probably wouldn’t like heavy ground. He’s just class with a super engine.”

Marine Nationale looks set to return to Leopardstown for the Dublin Racing Festival before returning to Cheltenham in March.

Connell added: “He’ll come back here for the Irish Arkle, then the Arkle and hopefully on to Punchestown. The script writes itself this year.

“He’s the horse of a lifetime and I’m just blessed that he came into our yard. They are one in 10,000 these horses.

“He’s taken a bit longer this year to get fit than last year as he had a proper break for 10 weeks, but he’s a tall, athletic horse and comes to hand quick enough.

“If you look at the list of Supreme Novices’ Hurdle winners, there are plenty that just didn’t train on and that was an added pressure.

“He had a little wind operation before he went out at the end of last season and we put a tongue strap on him today. We just thought it might improve him a bit.”

Supreme Novices’ Hurdle winner Marine Nationale will finally get his chasing career under way at Leopardstown over Christmas.

Barry Connell hosted the media at his County Kildare yard on Tuesday ahead of the big meeting over the festive period, and reported his stable star to be firmly on target for his seasonal return, having been delayed by soft ground.

Connell had hoped Marine Nationale would be contesting the Grade One Racing Post Novice Chase, but having yet to run over the bigger obstacles, he will take in a more modest event first.

When asked if all was in place for Leopardstown, Connell said: “Absolutely. His schooling has been 100 per cent. We schooled him twice on the grass at the Curragh and he’s a natural.

“His preparation has been good. He will do his last piece of work at the weekend and then, all systems should be go for Christmas.

“The original plan was to go to Navan, win a beginners chase there, then go for the Grade One at Christmas and then the Irish Arkle but we didn’t want to run him on heavy ground, so we had to forfeit the Grade One at Christmas and go for the beginners instead. But sure, look you have to adapt as circumstances change.

“Last year he won his maiden hurdle then went straight to a Grade One, so I don’t think that’s going to be an issue going to the Irish Arkle after his beginners.”

Connell has always had full faith in Marine Nationale – which was fully vindicated at Cheltenham – and says he knew from the first day the gelding entered the yard he was different.

“He is a one-off really, he is just an incredible athlete. From the first day we had him here, everything came easy to him,” said Connell.

“He is so relaxed as well which is a massive help. If you aren’t keen in a race you aren’t burning up excess diesel and you’ll have a horse for the finish.

“We didn’t want to start the season on heavy ground (at Navan). He can go to Leopardstown for his beginners and come back for the Dublin Racing Festival and then go on to Cheltenham hopefully.

“He is a light-framed horse. He has a preference for good ground, although he does go on soft.”

O’Connell used to ride his own horses and had them trained in various yards before setting out on his own.

“I’ve been a racegoer since I was one or two, my dad brought me racing since I was in the pram. And I’ve been to every meeting, went to Cheltenham, went to all the festivals when I was in school and college with friends and so forth. Then I bought a few horses and had them in training when I was in my late twenties, when I started working.

“I then took out an amateur licence and rode when I was 40 until I was 50. That allowed me to go around and have horses in training in a lot of different places and see how things are done. I always had it in the back of my head that I might like to try to do something like this. Really it was gathering the good staff together and putting the facilities in place, then buying the horses.

“I made loads of mistakes along the way, in terms of buying the wrong type of horse, having to deal with all the injuries and wear and tear that they have.

“We have a nice bunch of young horses there that we are getting going – probably 10 or 15 to run in bumpers and maiden hurdles. You know hopefully they will be the future.”
