Tiger Roll on course in bid to make Grand National history
Tiger Roll is the headline act among 105 entries for the £1million Randox Health Grand National.
Gordon Elliott's charge became the first horse since Red Rum to win back-to-back renewals of the Aintree spectacular last season.
The Gigginstown House Stud-owned 10-year-old is the 7-1 favourite with Betway to emulate Ginger McCain's legendary stayer by claiming the world's richest jumps race for a third time on April 4.
Elliott has made a total of 18 entries, more than any other trainer. If successful for a fourth time, the Cullentra handler would become the joint most successful trainer in Grand National history, alongside McCain and Fred Rimell.
Also among Elliott's team are leading Magners Cheltenham Gold Cup contender Delta Work and exciting novice Champagne Classic.
Willie Mullins has assembled a 10-strong squad, which includes Irish Grand National victor Burrows Saint, Topham Chase winner Cadmium and last week's Thyestes Chase hero Total Recall.
There are two previous Cheltenham Gold Cup winners in the mix, in Colin Tizzard's Native River and the Jessica Harrington-trained Sizing John, while Lucinda Russell's 2017 National hero One For Arthur could bid to regain his crown.
Harrington also has last year's runner-up Magic Of Light engaged - bidding to become the first mare to win the Grand National since Nickel Coin in 1951.
Bristol De Mai is one of seven entries for dual National-winning trainer Nigel Twiston-Davies - while other hopefuls include Robert Walford's dual Becher winner Walk In The Mill, Tom Lacey's Classic Chase victor Kimberlite Candy and the Sue Smith-trained Vintage Clouds.
The latter was an impressive winner of this month's Peter Marsh Chase at Haydock - and while connections were cool on a return to Aintree in the immediate aftermath, he has been entered.
Vintage Clouds fell at the first in last year's National and was pulled up in the Becher Chase over the famous fences last month.
Sue Smith, who tasted National success in 2013 with Auroras Encore, said: "After consideration we have decided to enter Vintage Clouds for the Grand National.
"Having discussed it at length with Trevor (Hemmings, owner), we decided that having won so well in the Peter Marsh, it was worth keeping our options open until nearer the time."
Other high-profile entries include the Paul Nicholls-trained Give Me A Copper, who is part-owned by former Manchester United manager Alex Ferguson, and Christian Williams' Welsh National winner Potters Corner - who counts Wales rugby union international Jonathan Davies among his owners.
