Ted Walsh believes even if Willie Mullins does not manage to emulate Vincent O’Brien by being crowned champion trainer in the UK when based in Ireland, both have played their part in changing the face of National Hunt racing.

Given the feats will be over 70 years apart – O’Brien was champion trainer for successive seasons in the early 1950s – Walsh feels it is difficult to compare their achievements.

However, he is left in no doubt that just like O’Brien, Mullins is destined to be remembered as a man who changed his sport.

“It’s very hard to compare anything like that because the prize-money was totally different,” said Walsh.

“Willie has never been that bothered about it, he admits it, but now he’s in front he may as well have a good go. He was very close one year when Vautour fell at Aintree (2016), if he had won Willie would have been champion.

“Whether Willie is champion trainer in England or not – it would be a great achievement, but he’s the real deal whether he does it or not.”

O’Brien was a pioneer who after dominating the National Hunt scene in the 1950s and 1960s, later switched his attentions to the Flat, winning the Triple Crown with Nijinsky in 1970. He remains the last man to win the Triple Crown.

“Vincent won three English Nationals with three different horses three years in a row (Early Mist 1953, Royal Tan 1954 and Quare Times 1955), three Champion Hurdles with Hatton’s Grace (1949–1951), the Gloucester Hurdle at Cheltenham used to divide and in 15 years he won 11 of them!” said an incredulous Walsh.

“Of course after doing all that he went and did the same on the Flat!

“He told me once that he always travelled first class on the train because there was a chance of meeting someone with money! He met John McShane on a train going to Doncaster for the sales and he bought him Ballymoss and Gladness. Ballymoss he won an Irish Derby, the Leger and the Arc and Gladness won the Ebor and the Ascot Gold Cup the following year.

“Vincent set the standard. I knew him, but whenever I saw him I would say ‘Hello Mr O’Brien’ – it was never Vincent. My father knew him well, he was from a similar area to us.”

The victory of I Am Maximus in Saturday’s Grand National means Mullins holds an advantage over Dan Skelton and Paul Nicholls, setting up a fantastic finale with Closutton set to be well represented at Ayr and Sandown over the next two weekends.

“Like Willie is now, Vincent was a hero, everybody looked up to him. I remember growing up as kid listening to my dad and my uncle Ted talking about Vincent,” said Walsh, who won the National with Papillon in 2000.

“I’d say it was pretty similar in those days of people getting sick of Vincent winning, he didn’t quite dominate Cheltenham like Willie does – but I’m sure people were sick of it!

“It was a huge achievement Vincent winning the UK title, I don’t know if he was the first man to try, but he was the first to do it. But Vincent did so many things first.

“He was the first to fly horses from Ireland, the first person to put in an all-weather gallop in Ireland and now everybody has them. He was a pioneer, he brought the sport forward years.

“Like Willie really, Willie has changed it as well but the scale of what he is doing makes it different. Transporting the horses now is different, they have lovely lorries with air conditioning, the roads are so much better so that makes it easier. Everything has moved on.

“I wouldn’t say one fellow was better than the other, but Vincent set the ball rolling and it hasn’t been done by anybody since Vincent.

“When I was growing up Vincent was inaccessible, he was almost treated like royalty, but Willie is the most approachable fellow, he’s very good for the sport and he’s a great ambassador for racing.”

Willie Mullins said it was “game on” in his pursuit of a first British trainers’ championship as I Am Maximus provided him with a second Randox Grand National victory.

While it has taken 19 years for him to follow up his initial success with Hedgehunter, his domination of the National Hunt scene on both sides of the Irish Sea is now such that he is odds-on across the board to win a title in a country in which he does not even reside.

The prospect of emulating the legendary Vincent O’Brien – who did it in successive years in the 1950s – has loomed large ever since Mullins once again commanded the Cheltenham Festival, winning the Champion Hurdle and Gold Cup in the process.

Mullins himself, though, played down the prospect, with one proviso – unless he won the £1 million National.

I Am Maximus was sent off the 7-1 favourite under Paul Townend, one of eight runners for the yard, and despite one or two hairy moments that are generally par for the course in a Grand National, he seldom looked like not winning.

With a lead of almost £40,000 over Dan Skelton, Paddy Power make Mullins the 8-15 favourite, and British racegoers certainly have not seen the last of the man from Closutton this season.

“I didn’t know we’d gone in front. You can expect to see us at Sandown, Ayr and wherever!” he said.

“We’ll have to go for it now. We needed to have a really good National and we have. It’s game on now, isn’t it.

“I’d love to win the championship. Vincent O’Brien has done it in the 1950s and it is something different to do.

“As much as I’d like to win it my owners would like me to win it and so would my staff, so now we’re in this position you have to have a real go.

“JP McManus (owner of I Am Maximus) has been telling me for the past couple of years to have a real go, but I always think just mind yourself at home rather than spread yourself too thin and leave yourself wide open to have a bad season at home.

“Travelling horses takes it out of them, especially early in the season, which is why we don’t do it, but it’s panned out well today.”

Mullins himself is taken aback by the quantity of the quality in his yard. But even for him, winning the Champion Hurdle, Gold Cup and the National is something special.

“You might have the favourites for all those races, but you don’t for one minute think you are going to win all three,” he said.

“We can’t believe it at home. We’re gobsmacked looking at the talent we have in the yard. When I was a smaller trainer I’d be proud to have one of the barns that we have.

“I have an amazing team, I don’t think I saddled a runner at Cheltenham, I let them do it and it probably works better when I’m not involved.

“If someone had said we’d have 100 winners at the Festival you wouldn’t have thought it was possible, so we’re as amazed as anyone that it happened.”

So it could be a very different end to the season for Mullins, with Sandown and Ayr occupying his thoughts rather than Punchestown, but Townend may not be on many of them.

“We have a different programme nowadays to when Vincent won it. I find the English programme very hard to navigate, it seems to be a lot of handicaps and that is tough on horses,” Mullins said.

“I’ll let David Casey (assistant), who plans those things, get to work on it. He’ll be working overtime over the next two or three weeks!

“Paul has a title of his own to try to win so I’m not sure if he’ll be coming over, he’s got four winners to make up on Jack Kennedy.”
