Tiger on a roll?published at 13:52 British Summer Time 6 April 2019
Last year's winner Tiger Roll is back to defend his title, hoping to become the first horse to land back-to-back Nationals since Red Rum in 1973 and 1974.
Trainer Gordon Elliott believes he has had better preparation than he had before the 2018 race.
"But it is the Grand National, you have more than four miles to go and a lot of fences to jump and 40 other horses to take on, so the best horse does not always win," he added in an interview with BBC Sport.
