Stamina, class, toughness and a little bit of luck are all part of the recipe for Grand National glory. Aintree's race has produced some remarkable tales over the years, from Bob Champion recovering from cancer to win on 1981 hero Aldaniti to AP McCoy's first win in 2010 at the 15th attempt.
A Virtual Grand National this year, as the UK battles coronavirus, will give Tiger Roll the chance of a third victory, a remarkable feat Red Rum achieved in the seventies.
Now is a perfect opportunity to look back at runnings of the race from years gone by- and Great British Racing have created their own bit of nostalgia by catching up with four previous Aintree heroes in retirement.
