Who could win the Grand National at the first time of asking?
David Mullins struck gold at the first attempt when winning the Grand National aboard Rule The World last year.
Over a quarter of the jockeys competing this seasonwill be having their first crack at the race, we assess their chances of following in the footsteps of Mullins.
Harry Cobden -Just A Par
He has been the outstanding conditional jockey in Britain this season with over 50 winners and a Grade 1 success on Irving to boot.
He has regularly been trusted with big rides by champion trainer Paul Nicholls who again trusts him on an interesting outsider here.
Just A Par has not been at his best at Aintree but has been in pretty decent form overall, and it is The Masters this week.
Jamie Codd -Cause Of CausesCodd may be officially classed as an amateur rider, but don't let that fool you. He has gone toe to toe with the professionals for many seasons, and knows what it takes to win on the big stage.
Cause Of Causes has been a willing partner on more than one occasion. The pair have won the National Hunt Chase, Kim Muir and Cross Country Chase in the last three seasons at the Cheltenham Festival.
A big run would not be a surprise.
Charlie Deutsch -Houblon Des Obeaux
Deutsch has made steady progress each season, and is enjoying his best campaign so far with 22 winners.
He was third on Houblon Des Obeaux in the Welsh National, and the ten-year-old is a thorough stayer, having also finished fourth in Warwick's Classic Chase and the Midlands National.
Venetia Williams won with 100-1 shot Mon Mome in 2009, and there will be worse outsiders to take a chance on.
Mark Enright -Thunder And Roses
Enright may not be that familiar a name to British fans, but he has been plying his trade with plenty of success in Ireland for the last few seasons.
Yet to have a winner in Britain, the Grand National would be some way to break the maiden, and Thunder And Roses is trained by Mouse Morris, who won it last year with Rule The World.
However, Thunder And Roses was pulled up when tackling the National fences in the Becher Chase in 2015, so improvement is needed.
Derek Fox -One For Arthur
A fractured wrist last month would have led to some sleepless nights for Fox, as in One For Arthur he has a leading contender to land the big prize.
Lucinda Russell's stable jockey will be aiming to take the trophy up to Scotland, and One For Arthur looks to have every chance.
Winner of the Classic Chase, the eight-year-old was only three lengths behind Vieux Lion Rouge in this season's Becher Chase, and should be involved at the finish.
Ger Fox -Raz De Maree
Another Irish rider who is not seen that often in Britain, Fox knows what it takes to win a National.
He has plundered the Kerry National and Irish Grand National on Rogue Angel, and the Cork National on Raz De Maree last November.
A 33-1 runner-up in the Welsh National, Raz De Maree has the form to be involved, but would be the first 12-year-old to win since Amberleigh House in 2004.
Adrian Heskin-Double Shuffle
Heskin moved to Britain to link up with trainer Tom George and the duo have quickly established an excellent relationship.
Came close to winning at Cheltenham with Singlefarmpayment and Heskin’s measured, calm approach means he is rarely in the wrong position in a race.
Double Shuffle is only a young horse and can throw in an error at key points. He has run well in general this season though.
Jack Kennedy -Roi Des Francs
Many great days lie ahead for this jockey, who was leading the riders’ championship until hampered by back-to-back injuries earlier in the season.
Steered the reluctant Labaik to Supreme Novices’ Hurdle victory last month and considered to be the heir apparent to Ruby Walsh. He’s only 17 after all.
Roi Des Francs won well in first-time blinkers last time but his overall profile leaves him with something to find.
Donagh Meyler -Measureofmydreams
Another name that may not be the most familiar to British racegoers, but this is a young rider who can get the job done in some style.
He has won the Galway Plate and Munster National this season, and has been regularly used by top trainers Gordon Elliott and Tony Martin.
Measureofmydreams wears headgear for the first time and hinted he was coming back to his best last time. It was only a hint though.
Jonathan Moore -Shantou Flyer
A season of two halves for this talented rider. He started his new role as first rider for Rebecca Curtis in style, capturing the Charlie Hall Chase at Wetherby on Irish Cavalier.
However, after 16 winners in September, October and November Moore has ridden less frequently in Britain, although he did claim the Grade 2 Reynoldstown Novices’ Chase in February.
Shantou Flyer won well on his debut for Curtis in January but may be up against it with plenty of weight on his back.
David Noonan -Ballynagour
Capped an excellent season by riding out his 3lb claim at Sedgefield earlier this month and is closing in on the 41 winners he rode last season.
Strong and determined, Noonan took less than two seasons to reach the 75-winner mark and he sits second in the conditional jockeys’ championship.
Ballynagour has been pulled up on his last three starts but was running okay in the Grand National last year before unseating.
