That statistic rules out eight runners including First Lieutenant, Wonderful Charm, Sir Des Champs, Soll, Buywise, Ucello Conti, Black Thunder and Pendra. Sorry Nina no female to win this year!

This category rules out another 17 runners that includes favourite Many Clouds, On His Own, Aachen, Vics Canvas, Vieux Lion Rouge, Ballynagour, Katenko, The Romford Pele, Home Farm, Hadrian’s Approach, Kruzhlinin, Shutthefrontdoor, Triolo D’Alene, Gilgamgoa, Double Ross, Ballycasey and Rule The World.

That leaves the following horses in general price order: 12 THE LAST SAMURI 14 SILVINIACO CONTI 16 THE DRUIDS NEPHEW 16 HOLYWELL 18 SAINT ARE 18 GALLANT OSCAR 22 GOONYELLA 25 MORNING ASSEMBLY 33 BOSTON BOB 33 UNIONISTE 40 ONENIGHTINVIENNA 50 JUST A PAR 66 LA REVE 80 ROCKY CREEK 

Interestingly six of the last 10 winners ran over hurdles in the same season though that did not apply to Many Clouds last year. No horse younger than 8yo has won the race since 1940 and we have to go back to 1923 to find a winner older than 12yo.
