The Grand National is the biggest event of the British racing calendar, with 40 horses taking to the iconic Aintree fences over the course of 4m 2.5f.
The winner of the steeplechase will receive a £500,000 share of the £1 million prize pot, but it is not a simple race to win with 16 fences to navigate - 14 of which are jumped twice - before a victor emerges.
The race is a handicap event, which means each horse is rated beforehand and weighted accordingly so as to ensure a level playing field. This further complicates the betting market and makes the race the most eagerly anticipated in the National Hunt calendar.
