With over 10 million viewers tuning in each year and £300m bet on the big day in the UK alone, the Grand National is the premier event in the racing calendar.
Held at Aintree since 1839, the first race was won by the aptly named Lottery, with a time of 14 minutes 53 seconds, the slowest ever recorded. Punters are always on the lookout for value bets and regulars know it isn't always the favourites that end up taking the £1million prize home.
Minella Times won the Grand National last time out in 2021, starting the race at 11/1, but horses have won the Aintree main event at a whopping 100/1. This was achieved by Tipperary Tim (1928), Gregalach (1929), Caughoo (1947), Foinavon (1967) and Mon Mome (2009).
