He could have been forgiven for thinking ‘what if’ when former pupil I Am Maximus sauntered his way to Randox Grand National glory – but Nicky Henderson was simply thrilled for all concerned and three days at Aintree he feels the sport can look back on with pride.

It still seems remarkable Henderson has not trained a National winner during what continues to be a hugely distinguished career, and it is perhaps indicative of his luck in the world’s most famous steeplechase that I Am Maximus was housed at his Lambourn base before switching to Willie Mullins in Ireland.

The future National hero won both a Cheltenham bumper and a Newbury novice hurdle while in the care of Henderson, who admits he was the one runner he was keeping a close eye on during Saturday’s main event.

“I’ve let one slip through the net,” quipped Henderson. “It’s ironic, you spend 45 years trying to win the Grand National and you finally get your mitts on one and we let it get away.

“He was here and spent his first two seasons here – he was a lovely horse – and he was the one horse I wanted to win yesterday.

“I suppose the only thing I might have done to contribute to his success was probably the way we minded him quite a bit when he was young, because he was big and backwards and raw.

“He was a lovely horse with a great temperament, but he wasn’t really ready for big battles in those days and just needed to be treated with respect – and I think that’s what we did.”

He was owned at the time by Michael Grech, who was to switch all his horses to Ireland in the summer of 2022, with I Am Maximus joining Mullins’ swelling Closutton ranks to embark on a novice chasing campaign which culminated in Irish Grand National success in April 2023.

Grech sold I Am Maximus to JP McManus before that Fairyhouse triumph and sadly did not get to see his former charge’s finest hour at Aintree, having died in September last year. But Henderson believes the horse’s big-race victory will be a lasting tribute to his good friend.

He continued: “I’m thrilled, he belongs to JP, who is one of my biggest supporters here and Willie is a great mate – I told him he needed to go get that horse. I’m genuinely thrilled for them.

“Sadly, he had to move on (from ourselves) and Michael Grech was lovely, we had some tremendous days together and it was great fun. The horses then had to go over to Ireland and sadly Michael died and it’s very sad because he was a lovely man.

“All his family were there yesterday, Maxine (his wife) and his children and it was a sad day for them, but he won in Mike’s memory.”

Henderson did not have a runner in this year’s National, but was keen to heap praise on officials at Aintree for not just the successful alterations they made to the race itself, but for the three days in Liverpool overall.

The 73-year-old roared back to form himself on Merseyside after a testing Cheltenham Festival, with star performers Sir Gino and Jonbon both scooping Grade One honours.

He described the action on Merseyside as the “best three days racing you could wish to see anywhere”, with racing deserving of a massive pat on the back after a thrilling three days of action in the north west.

“I thought it was a fantastic race and it was a brilliant three days, you won’t see better racing anywhere,” said Henderson.

“Aintree need huge credit for it and after Cheltenham everyone was so down and out, it was all so gloomy and everything was wrong, so after all that, we need to say this was brilliant.

“I wasn’t going round Cheltenham doom and gloom because I couldn’t play, but I was back playing the game again this week which was good fun and the horses ran well throughout the week.

“It was a fabulous Grand National, with lots of horses getting round and everyone safe and sound, which is always a paramount – and I just thought it was the best three days racing you could wish to see anywhere and it wants to be celebrated and paraded and everyone saying well done to everyone.

“The sport did very well for three days and I know we are all under the cosh at Cheltenham and under pressure and maybe things get a bit heated or overtried, but up at Aintree everyone was there to have a good time and enjoy it and they did – and I thought it was first class all the way through.”
