If you could see into the future, ten minutes would be just enough time.
You'd have been at Aintree, Liverpool, the home of the Grand National, and mysteriously know the name of the winning horse.
You'd have been disappointed back in 2001 as Red Marauder completed the greatest steeplechase in the world with a winning time of 11m 0.1s. Even worse, you'd have missed out on the odds at 33/1.
All recent winners have been right on time.
You would have been laughing all the way to the bank.
Highlights would be Mon Mone winning at 100/1 in 2009. A very pleasing 9m 32.9s.
To be honest, if you knew the outcome of a race before it started a mighty odds-on would be tempting.
A brazen smile as you placed your bet. We're talking suitcases.
This year's Grand National takes place on the 10th April. To give the race its full title: The Randox Grand National Handicap Chase (Grade 3) (Class 1) 7yo+
The winner gets prize money worth £375,000.
For many, the accolade of winning is worth even more.
Which of the 2021 horses and jockeys will prevail? There will be a maximum of 40 runners. At present there are 77 entrants.
Until the horses have been selected it is difficult to know which jockeys will be riding which mounts.
However, you can guaranteed certain owners and trainers will have their pilot waiting ready for the off.
In recent years, Tiger Roll has been the talking horse, winning consecutive races in 2018 - 2019. Sadly, he couldn't try and emulate the third success of the legendary Red Rum, beaten by an impossible opponent in Coronavirus.
It is disappointing to hear that Tiger Roll won't take his chance this year and heads to the Irish Grand National which takes place at Fairyhouse on the 5th April.
This time round, we have a strongly fancied favourite in Cloth Cap, trained by Jonjo O'Neill who won the National back in 2010, giving Tony McCoy his only success in the race and putting a smile on the face of many including owner J. P. McManus.
Cloth Cap has been well supported at 9/2 and may be one of the shortest priced favourites for over a century
Trevor Hemmings is the owner of Cloth Cap. This billionaire businessman is no stranger to success as he has won the Grand National three times since 2005 when Hedgehunter landed the odds at 7/1 in a time of 9m 20.8s.
That wasn't the best kept secret.
The Grand National is a race full of stories. This April, another story will be told. Perhaps it will be a winning favourite. It could possibly be a horse at odds of 100/1. Wouldn't it be something if this year saw the first female jockey win this biggest prize.
You'll have to wait until after the race because I'm keeping this secret under my hat.
