Ruby Walsh: The 5 things you need to win the Aintree Grand National

Have you won the world's most famous race twice? The top jock rides Pleasant Company on Saturday and gives us the skinny on what he'll need to be crowned King

With 40 horses, 30 fences, and the ability to gallop four miles you need a fair slice of luck to win a Grand National. However, if you can tick these 5 boxes  – you’ll go there with a great chance.

1. Stamina

There aren’t many races run over four miles, so what you need are horses that are regularly seeing out trips over 3m 4f or longer.

If a horse is wheezing after running three miles, then what chance does it have of winning over a mile further?

With the history and sense of occasion, some owners are naturally very excited with the prospect of having a runner in the National.

Often they can ignore that their horse isn’t really suited to the extreme trip, although the qualifying criteria now means there are less blatant, non stayers in the race.

2. Good jumping

The clue is in the sport’s name: jumps racing.  But it’s often overlooked.

Good jumping is not the ability to put in one or two monster leaps before nearly come crashing down at the next fence. It’s about consistent, solid jumping from fence to fence.

It’s not a bad thing to see a horse being more economical with their jumping style. They mightn’t catch the eye as much, but that’s not a bad thing as long as he’s steady.

The ability to stay on your feet for 30 fences is more important than looking good at one or two and then ending up face down on the turf.

3. Aintree experience NOT essential

There seems to be a popular trend in recent years in looking for horses who had raced over the National fences previously.

I never really bought into it then, I don’t buy into it now. Rule the World won it in last year on his first visit to the place, Many Clouds’ form there never indicated he was in love with the Liverpool track before winning  in 2015 and Pineau De Re fell on his first visit to Aintree before winning the National in 2014.

Both Auroras Encore and Neptune Collonges hadn’t been over any Aintree fences before they won it either. Experience can help – but it’s obviously not crucial.

4. Under the radar

The Grand National is such a huge prize and such a gruelling race, it’s rare you get a horse who is performing at his or her best throughout the season and then goes on to win at Aintree.

Trainers need to build-up the horse’s stamina and if that means having a couple of uninspiring runs around Plumpton or Fakenham, then so be it. From my point of view, I wouldn’t judge a horse too harshly if he hasn’t been bossing races. It’s hard for a trainer to keep a horse at his peak for six months of the year. So if Aintree was always the target, I’d be willing to excuse a sub-standard run if it looked like there was more to come.

Some of the form figures heading into the National won’t look too impressive, but bear in mind that we may not have seen the horse at his or her best this season.

5. A touch of class

It sounds a bit vague, but you’re looking for something in the horse’s history that on a given day, they can mix it with the best.

Last year’s winner, Rule the World, had finished second in an Irish Grand National 12 months earlier Many Clouds had finished sixth in a Gold Cup before winning the race in 2015. Pineau De Re won an Ulster Grand National and finished seventh in the Champion Bumper years before.

Despite being a 66/1 chance, Auroras Encore had finished second in the Scottish Grand National the year before.

Neptune Collognes had run well in a couple of Gold Cups and some graded races.

It may sound a bit like ‘being wise after the fact’, but when you look back at a Grand National winner’s form, there will generally be some pieces of form that hint at quality – and a big race to come.
