The Grand National is renowned for big prices, drama and punters hoping to win big.Since its inception in 1839 it’s no surprise there’s been some big shocks and some huge priced winners.Tipperary Tim was probably the biggest shocks in Grand National historyGettytalkSPORT BET betting offer: Get up to £35 matched if your first bet loses – CLAIM HEREThere’s been a fair few short prices recently, Tiger Roll won as the 4/1 favourite in 2019 to secure back-to-back Grand Nationals after his incredible win in 2018.In fact there’s been 52 winners at single digit prices, so it’s even more memorable when horses who are at big odds get past the line first, but who are the biggest shocks and biggest priced winners?Top ten biggest Grand National shock winnersLast horse standing – Tipperary TimThe first ever 100/1 winner of the Grand National and the highest ever priced winner was Tipperary Tim back in 1928.Tipperary Tim will always go down in history for the biggest shocks in the race, as there’s only one horse that can do it at this price for the first time.But it wasn’t just the price of 100/1 that was the most shocking.It has been reported that the jockey William Dutton’s friends shouted to him before the race that he’d only win if every other horse failed to finish.But they were true, all other horses fell, or pulled up due to the awful conditions on the day after a weeks of rain.As the race neared its end Tipperary Tim still needed a miracle, as great Span led the way… until his saddle slipped opening up the chance for Billy Barton to win.Only for him to fall as well, leaving Tipperary Tim the most astonishing winner of all.Mon Mome 100/1Punters had to wait decades to see another 100/1 winner in the Grand NationalGettyThe fifth joint biggest priced winners in National history and the biggest priced winner since 1967, at a massive 100/1.The Venetia Williams-trained winner Mon Mome goes down as one of the biggest shocks in horse racing.It’s rare to see 100/1 winners let alone in the biggest jumps race of the year.The reason he was not fancied to win was his form prior to winning the 2009 national.He finished a disappointing eighth place a huge 57 lengths behind the winner at Uttoxeter in the Midlands Grand National the month prior.It called to question his stamina over anything over 4m, especially having also finished in similar fashion in the 2008 Grand National, when placing tenth.His only other race over 4m+ was at Ayr in the Scottish Grand National, where he also finished 47 lengths off the victor.So it was a bit of a shock when Mon Mome who was towards the back of the field at the start of the race, went on to bypass almost all runners steadily and surged on to win by 12 lengths!Foinavon 100/1The 1967 Grand National will always go down in history as the biggest shocks and top moments of the famous race.So much so that the 23rd fence in the race was named after the winner Foinavon in the aftermath.At 100/1 he is amongst the five biggest priced winners of the race, but it was also the way in which he won that also grabbed the attention of viewers.At the 23rd fence, a loose horse by the name of Popham Down caused mayhem, resulting in a plethora of horses unseating riders, fallers and more.Foinavon was far enough behind to avoid all that by the time he came to the fence, which saw him gain the lead as jockeys scrambled to get back on their mounts.If 100/1 was big, it is said that Tote punters managed to get 444/1 is even more memorable.Gregalach 100/1What’s more surprising is that punters only had to wait a year to find the next 100/1 winner after the first with Tipperary Tim.As Gregalach won just 12 months later in 1929 after that shocking victory in 1928.That year saw as many as 66 runners, a record even at that time for the most runners, where the prize for the winner was £14,000.Those winnings, adjusting for inflation, would be the equivalent of nearly £780,000 in today’s money.45 camera operators were deployed across the Aintree course, which shows how big the race is as it was a World record number at one event.Remarkably he beat the favourite Easter Hero who was carrying a mammoth 12st7lb who somehow finished second.Auroras Encore 66/1Ryan Mania riding Auroras Encore to win in 2013GettyThe 2nd highest priced winners of the Grand National are 66/1, there’s only been four such victories at that price.And one of them came in 2013 with the 11-year-old Auroras Encore.He was one of the lowest rated for that renewal so only carried 10st3lb on the day.The 11/2 favourite Seabass finished over 85 lengths behind placing 13th of the 40 runners, in a race that largely fell apart for most horses.A total of 23 horses didn’t finish, where one even refused to race, while only two fell and a huge 14 pulled up.To make matters more shocking, it was jockey Ryan Mania’s first ever ride in the race, where he guided Auroras Encore to win by nine lengths.CaughooCaughoo was the only other 100/1 winner, the eight-year-old under jockey Eddie Dempsey trained by Herbert McDowell, owned by John McDowell.There are a few aspects that make this one for the history books and again not just for the odds.Fog absolutely covered the track on the day and after the race allegations came out that the jockey had hidden the horse behind one of the jumps.But that was soon debunked… after 50 years! When film of the race was able to be analysed.The win was a huge one for Ireland as the Irish-trained horse emerged from the fog to win for the nation.It was also just the second Grand National after the Second World War prompted the abandonment of the race between 1941 and 1945.66/1 winnersAuroras Encore won at 66/1 and there are just three others to win at that price: Rubio in 1908, Russian Hero in 1949 and Ayala in 1963.Making these and the above the top nine priced and shocking winners of the biggest race in the world.talkSPORT BET Boosted Favourites30 minutes before the start of every UK & IRE race, we are boosting either the favourite or 2nd fav to win!Get the latest price boosts here18+.
