During its 180 year history, the Grand National has seen only five horses win consecutive runnings, with this year's victor Tiger Roll joining that exclusive list of dual winners.

Until the legendary Red Rum, the last horse to win on his immediate return to Aintree was Reynoldstown, who won the 1935 Grand National in the hands of Mr Frank Furlong - a subaltern in the 9th Lancers - and again the following year ridden by Furlong's great friend and fellow Army officer Mr Fulke Walwyn, later to become a multi-time champion National Hunt trainer.

Although two totally different kinds of horses, the long, lean, black Reynoldstown and the diminutive Tiger Roll share a parallel in that both had Flat-bred sires. Reynoldstown was by the good-class My Prince who won among other races the Union Jack Stakes at Aintree but went on to become more famous as an outstanding sire of National Hunt horses including Grand National winners Gregalach (1929) and Royal Mail (1937), while Tiger Roll's father Authorized won the 2007 Epsom Derby under Frankie Dettori. Reynoldstown's dam Fromage was the product of a modest mating to the nearest sire who was within walking distance.
