Tiger Roll is bidding to become the first back-to-back winner of the Grand National since the great Red Rum completed the feat back in 1974.
He is one of 11 runners for trainer Gordon Elliott, whose team also numbers Bless The Wings, the well-fancied Jury Duty and the 2018 Irish Grand National victor General Principle.
Rathvinden leads the Willie Mullins squad, and will be ridden by Ruby Walsh, with 2018 runner-up Pleasant Company aiming to avenge his head defeat for the master of Closutton.
Walsh explained his decision to ride Rathvinden.
He said: “He has 11st, which is a nice weight. He won the Bobbyjo, won last year’s four-miler at Cheltenham, and he’s in good form – so I sided with him.
“He beat Ms Parfois in the four-miler, with Jury Duty in behind, so it’s solid form.
“He’s a safe jumper who stays – but he’s won over shorter, so he’s got pace.
“He ticks a lot of boxes – but you still need a lot of luck.”
Cheltenham Gold Cup runner-up Anibale Fly carries top weight for trainer Tony Martin, with the Trevor Hemmings-owned pair of Vintage Clouds and Lake View Lad also prominent in the betting.
Champion jockey Richard Johnson has yet to the win the National and he will team up with the Philip Hobbs-trained Rock The Kasbah as he tries to end his luckless run.
Becher Chase winner Walk In The Mill, 2017 Grand National hero One For Arthur and Step Back – for Gold Cup-winning trainer Mark Bradstock – are other names to note.
In a late twist yesterday, owner Philip Reynolds revealed Mall Dini had picked up an injury and would miss the race, meaning first reserve Just A Par, trained by Jimmy Moffatt, gets a run.
