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.”
