As much as £300m will be gambled on the The Grand National and the steeplechase is said to attract over 500 million global viewers.
The most anticipated event in horse racing's calendar for many, the famous race has appeal outside of normal racing circles, with many usually non-interested punters picking a horse as a tradition.
First held in 1839, with the aptly named 'Lottery' winning, Saturday will see the 175th iteration of the race held in front of thousands of spectators at Aintree. Though the public and bookies have their favourites, the Grand National is no stranger to having an outsider win.
