David Mullins, riding Rule The World, celebrates winning the 2016 Grand National steeplechase at the Aintree Racecourse in Liverpool, England.

The 33-1 shot overtook the Last Samuri (8-1) and Vics Canvas (100-1), which finished second and third respectively, late on to claim the £561,300 ($793,000) winner's prize.

The Grand National is the UK's most famous horse race and organizers estimated it would be watched by 600 million people around the world.

The 75,000 capacity racecourse was also packed with fans keen to have a flutter on the outcome of the 169th version of the annual race.

Mullin and Rule The World clear the last fence on their way to victory.

Last year's winner, Many Clouds, ridden by Leighton Aspell, challenged early on but finished back in 16th.

Fans look on engrossed by the action at the Aintree race course.

Run over a distance of four miles and four furlongs, the Grand National is among the the UK's sporting crown jewels, alongside the likes of the Varsity Boat Race, Wimbledon and British Open golf championship.

Jockeys Nina Carberry and P.W Mullins lie on the ground after falling from their mounts at The Chair fence -- an occupational hazard in the race business.

Scores of riders charge down the stretch at the Grand National steeplechase.
