The 2004 Grand National (officially known as the Martell Grand National for sponsorship reasons) was the 157th official annual running of the world-famous Grand National steeplechase which took place at Aintree near Liverpool, England, on 3 April 2004 and attracted the maximum permitted field of 40 competitors for total prize money of £600,000 including £348,000 to the winner. For the second year running Bramblehill Duke was a late replacement for the withdrawn Red Striker a day before the race.
