The nature of the National has changed in recent years; this year, for the first time, the field size has been reduced to 34 runners and the first fence has been re-sited 60 yards nearer the start.
The going on the National course is currently described as soft, heavy in places, with Turftrax identifying the deep areas as Becher's Brook through the Canal Turn, Valentines and beyond; the ground between the first three fences racing away from the stands and between the Chair and the Water Jump is now described as soft and has dried out since yesterday.
Since 2015 the race has been run on ground classified as soft or heavy twice (2016 and 2018); a horse aged eight or nine has won seven of the eight renewals in the same time frame:
2015: Many Clouds 8-11-09; OR 160; 19/39 runners finish; official going: good to soft
2016: Rule The World 9-10-07; OR 148; 16/39; soft
2017: One For Arthur 8-10-11; OR 148; 19/40; good to soft
2018: Tiger Roll 8-10-13; OR 150; 12/38; heavy
2019: Tiger Roll 9-11-05; OR 159; 19/40; good to soft
2020: No race - cancelled due to Covid
2021: Minella Times 8-10-03; OR 143; 15/40; good to soft
2022: Noble Yeats 7-10-10; OR 147; 15/40; good to soft
2023: Corach Rambler 9-10-05; OR 146; 17/39; good to soft
Last year Corach Rambler beat Vanillier (10-06) two and a quarter lengths with Noble Yeats (11-11) a further six and a quarter lengths adrift in fourth (Roi Mage seventh; Delta Work unseating at 21st fence; Mr Incredible unseating after slipped saddle at Canal Turn on second circuit; Coko Beach pulled up after weakening three out; Capodanno pulled up before last after weakening two out).
Mark Walsh had the pick of the five J P McManus owned runners and opted to ride the mare Limerick Lace; the last mare to win the National was Nickel Coin in 1951.
I Am Maximus and Meetingofthewaters, both trained by Willie Mullins, have been well supported in the market.
The former gave 12 pounds and a 14 length beating to Vanillier in the Bobbyjo Chase at Fairyhouse seven weeks ago; he was subsequently raised to a mark of 164 in Ireland but races off 159 in this.
Meetingofthewaters finished third behind Chianti Classico in the Ultima at Cheltenham four and a half weeks ago.
Willie Mullins saddles a total of eight runners in all - Mr Incredible was a creditable second in the Midlands Grand National at Uttoxeter last month - and has indicated he'll consider an all-out assault on the British trainers' title should one of the eight come home in front here.
Gordon Elliott also saddles eight and has nominated Delta Work his best chance; the last 11-year-old to collect the spoils was Pineau De Re in 2014.
If the ground remains testing, Noble Yeats, Chemical Energy, Galvin and Kitty's Light are unlikely to be seen at their best.
Nassalam won't mind underfoot conditions.
Gary Moore's charge beat Iron Bridge 34 lengths on heavy ground in the Welsh National at Chepstow but was raised 16 pounds for that effort - the handler has publicly made his displeasure known with such a large hike.
Panda Boy finished fifth behind I Am Maximus in the 2023 Irish Grand National at Fairyhouse and four and a half lengths behind Meetingofthewaters at Leopardstown over Christmas; trainer Martin Brassil won this race in 2006 with Numbersixvalverde.
The mare Galia Des Liteaux ran well when second behind My Silver Lining on her first try over an extended trip in Warwick's Classic Chase but looked to struggle on heavy ground at Exeter next time out.
Mahler Mission is one I like although he has his share of weight.
John McConnell's inmate was four lengths clear in the 2023 National Hunt Chase at Cheltenham when coming to grief two out; the winner that day, Gaillard Du Mesnil, was rated 155 (Chemical Energy second).
Last time he had no answer to Datsalrightgino on good to soft ground in the Coral Gold Cup at Newbury, a race in which he lost both his front shoes. The gelding went off 151 that day with Ben Harvey able to claim three, so a mark of 158 here looks stiff enough.
Quoting the handler [RP Weekender 27-31.12.23]:
"... but the Grand National is his main aim and you'd imagine he should take to that. He's a very good jumper and you'd think he was made for it. It's such a big prize and it's too good an opportunity to waste with a horse like him who's on the improve. The trip probably won't be a problem but I don't think he's slow and he has a bit of class about him."
The BBC Pinstickers' Guide is likely to prove more useful than this rambling post but, for those interested, Mahler Mission is the each-way suggestion, currently 12/1 generally with most layers paying six places.
As always, check each-way terms before placing bets. Firms with an online presence as well as a High St outlet tend to pay more places for bets placed electronically.
It just remains for me to wish you all the very best of luck!
