Ben Linfoot looks through the horses that are 'well-in' at the weights, have form over the Aintree fences, have proven stamina and more ahead of the Grand National on Saturday.
Anibale Fly will be the horse most 'well-in' at the weights in this year's Randox Health Grand National.
Now rated 168 after an excellent third in the Timico Cheltenham Gold Cup, he gets to race off a 9lb lower mark at Aintree and given the way he finished his race at the Festival it could well be that he'll relish the stamina test as well.
He took a heavy fall in the Irish Gold Cup at Leopardstown in February and isn't the most fluent of jumpers, while he has no experience of Aintree, either.
However, despite that, he looks to have the most obvious form claims and should arguably be favourite following his Cheltenham exploits. Crucially, because of the timing of Easter, there is an extra week's recovery time this year between Cheltenham and Aintree.
That will also help Shantou Flyer following a terrific effort at Cheltenham, while Regal Encore will go into the race after a 56-day break - exactly the same number of days he had off prior to his latest win at Ascot.
Plenty of horses in this year's National have experienced the famous race before. Four of this year's runners have placed in the first four in the race before; Blaklion, The Last Samuri, and Saint Are. There are no previous winners running this year.
Blaklion runs off a mark 9lb higher than when he was fourth last year, The Last Samuri is 10lb higher than when he was second and the 12-year-old Saint Are is on exactly the same mark of 147 as when third last year.
Not much to see here apart from perhaps some vital Aintree experience for Bless The Wings.
He is 13 now and it's surprising he's yet to run in the Aintree spectacular, but he didn't really take to the famous spruce when making mistakes on his way to a 45-length ninth in the 2015 Topham.
Several National regulars ply their trade in the Becher earlier in the season and that's been the case for Saint Are, Vieux Lion Rouge and The Last Samuri the last couple of years.
This season's Becher was all about Blaklion, though, his nine-length victory over The Last Samuri off a mark of 153 the major reason as to why he's disputing favouritism at around 12/1.
Winning form in the Grand Sefton for Gas Line Boy enhances his chances for the big one, while Captain Redbeard was stopped in his run when hampered at the fourth last this season.
He was going well at the time and has run well since, so he's a possible lively outsider towards the bottom of the weights.
Plenty of recent Grand National winners have had good previous form on the conventional course. Mon Mome, Don't Push It, Neptune Collonges and Many Clouds had all either won or been placed on the Mildmay Course prior to their National successes.
Neptune Collonges was third in the Sefton as a novice hurdler, which bodes well for Seeyouatmidnight, while the handicap chase wins for Mon Mome and Don't Push It gives hope to Dan Skelton's Virgilio, a horse that bolted up off just a 3lb lower mark than the one he races off in the National when he won at the Liverpool track last May.

(Won over 3m5f+ / placed over 4 miles)
It might not be quite four-and-a-half miles anymore, but the official distance of 4m2f74y still takes some getting and it's no surprise horses that have proven themselves over long distances before have gone well.
Comply Or Die won the Eider Chase over four miles less than two months before his 2008 National win, Mon Mome had been second in a Welsh National and Classic Chase before his 100/1 shocker in 2009, Auroras Encore had been second in a Scottish National before his 66/1 Aintree success in 2013 and One For Arthur had won the Warwick Classic Chase before he won last year.
There's a big list to go through above this time around, but the interesting one could be Vicente. He got no further than the first fence in last year's Grand National, but won the Scottish version for the second time just two weeks later.
He started his season well when a neck second to Perfect Candidate at Cheltenham in November, but has gone off the boil in two starts subsequently. The winter ground is a viable excuse for him, however, and if conditions turn up on the Good side he'd have to be considered.
In recent years, thanks to the way this race is handicapped and the modifications to the fences, top-class horses have been running more and winning more.
Neptune Collonges won in 2012 having been previously third in a Cheltenham Gold Cup, Many Clouds won in 2015 having run in three Grade Ones and Rule The World won at 33/1 in 2016 having run six times at the top level.
He was owned by Gigginstown and, unsurprisingly, they are responsible for the prolific Grade One runners this year - if they turn up. Valseur Lido, Alpha Des Obeaux, Tiger Roll and Road To Riches are all possibles this year and they have run at the top level 47 times between them.
Blaklion was arguably unfortunate to be only fourth last year and set the record straight with a resounding success in this season's Becher.
Virgilio has some excellent Aintree form, all on the Mildmay track, and it's not a surprise he's been sent for wind surgery with connections citing a wind problem before.
He'd probably need good ground and he's never tackled the fences, but he's handicapped to go well and if the procedure works he's a very lively outsider.
Pendra has a lot to prove currently.
Horses that have won over fences on Soft or worse ground...
With the Grand National course officially Soft, Good to Soft in places on Tuesday morning (10/04/2018) and more rain forecast, we could well be looking at a very testing Grand National.
As you can see from the list above, there are plenty of mud lovers in the line-up. Perhaps, then, it's more useful to mention the horses that aren't there.
Anibale Fly has won on Yielding to Soft at best over the bigger obstacles, while Saint Are hated the last Soft ground National he ran in but bounces off the better spring ground in Liverpool. Virgilio is another that has excelled on much better conditions at this track.
