With 30 fences to be jumped over four-and-a-quarter miles, it is no surprise the Grand National produces some shock results.
Over the years, there have been five 100-1 winners of the Aintree marathon – Tipperary Tim (1928), Gregalach (1929), Caughoo (1947), Foinavon (1967) and Mon Mome (2009). The shortest odds winner was Poethlyn in 1919, who went off at a price of 11-4.
And in the last ten renewals, horses with odds of 66-1, 50-1, 33-1 and 25-1 have been successful.
