Tiger Roll will not run in the Aintree Grand National this year.

Following the publication of the weights for the race, Tiger Roll's owner Michael O'Leary issued a statement confirming that the dual winner of the race would not run in this year's edition.

It means that the horse is set to miss out on the chance to emulate the achievements of Red Rum in winning the famous steeplechase three times.

Tiger Roll won the race in 2018 and 2019, but missed out on the chance to defend his crown in 220 because the race was not held due to the pandemic.

The horse did not run in the race last year because the owners felt that the handicapper gave him too much weight to carry, and, for the same reason, he will not be competing at Aintree this year either.

Tiger Roll is now 12 years old, and his owner, Michael O’Leary, feels that it is ridiculous to ask a horse of his age to carry such weight.

Instead, he could be retired after the Cheltenham Festival next month, where he will be chasing his sixth success.

The Grand National is a handicap race held annually over a distance of four and half miles, two a half furlongs at the Aintree race course near Liverpool.

First held in 1839, and it is the one race where people who don't take any interest in horseracing for the rest of the year will sit down and watch, and many of them will have a bet, often for just a few pounds.

That is in addition of course to the serious punters who will place thousands of pounds on the outcome of the race, along with their more traditional betting events like online casino games.

The most famous Grand National horse of them all was Red Rum.

Bred in Co Kilkenny, he won his first Grand National in 1973, winning the race in a record time of nine minutes and two seconds. The following year he defended his title and also won the Scottish Grand National as well (the only horse in history to win both in the same season).

He came second in 1975 and 1976, but, the following year, at the age of 12, he won the race for an unprecedented third time, many regarding the moment he crossed the finishing line as the most memorable in jump racing history.

An attempt at a fourth success the following year was ended when he developed a hairline fracture, and, instead, he settled into a happy retirement where the horse became a personality in his own right, opening supermarkets, making celebrity appearances, and leading the Grand National parade before the big race itself for many years.

His image adorned mugs, posters, puzzles, playing cards and plates. He was the subject of several books, and he even had a pop song issued as a tribute to him.

When he died at the grand old age of 30, he was buried at the winning post at Aintree.

Even today, he remains the best known racehorse in Britain, ahead of the fictional Black Beauty.
