Teaforthree finished ahead of Teaforthree when they met in last season’s Welsh National and Michael Scudamore’s charge has been the subject of strong market confidence in recent weeks. Monbeg Dudehas been a strong fancy for the race for some time and was third in last year’s renewal. Trained by Rebecca Curtis, he ran well for a long way in the Cheltenham Gold Cup and any rain wouldn’t be to his disadvantage.

. At thirteen, the statistics are very much against him but he showed he still retains his enthusiasm with a solid third in this season’s Welsh National.Tidal Bay is undoubtedly the class act in the field having landed the Cheltenham Gold Cup in 2011 and won the King George VI Chase at Kempton on two occasions. Although he’s not lived up to those heights this season, his presence at Aintree is all the more interesting.Paul Nicholls won the race in 2012 with Neptune Collonges and attempts to repeat the dose with Long RunAmong his part-owners is former England Rugby Union ace, Mike Tindall, and his wife, Zara Phillips.Nicky Henderson is yet to win a Grand National and the current champion trainer has four runners in Saturday’s showpiece.

He made a belated seasonal reappearance at Cheltenham last month where he finished an eye-catching third, and with Tom Scudamore riding so well at present, it’s no surprise that his odds have tumbled in recent days.  ^thwould come into this category.

Shakalakaboomboom probably has the best name of the forty starters but he’s certainly no mug bet if Nicky Henderson can have him back to his best.He finished ninth under what was probably too positive a ride in his previous experience of the National, but injury has meant that we haven’t seen a great deal of him since.Two recent runs have been nothing to write home about although he performed particularly well in a race around Kempton’s Flat track earlier this year, and the fact that his owners have persevered with a couple of years of training fees suggests that he must have shown something worthwhile on the gallops.

Ryan Mania managed the feat last season on Auroras Encore and followed in the footsteps of Liam Treadwell, who won the 2009 renewal on 100/1 outsider Mon Mome.Nick Scholfieldwent close on Whats Up Boys in 2002 though he has at least got completed the course in three of the last four contests. Richard Johnson There are, however, a number of high profile riders that have never won the National.

Trainers

Nicky Hendersonhas a particularly impressive record. Walsh sent out the well-backed Papillon to victory in 2000 and he has placed with a further two of his other nine runners over the years. Ted Walsh is another to have followed in the footsteps of his father with Comply Or Die (2008) but from a statistical perspective, David Pipefamily have been the masters of Aintree having made it their own through the exploits of Red Rum (1973, 1974 and 1977); Amberleigh House (2004) and Ballabriggs (2011).  McCain ’s record of never winning a National is clearly a rare gap in his CV but the

Depending on the ground

The ground is one of the most important things in racing and while some sunshine anticipated ahead of the Grand National, there are also a fair amount of showers. Recent renewals have seen the going generally good or good to soft and the state of the going can often effect the number of finishers in the race. The Nationals of 1998 and 2001 were staged on going officially described as “heavy” and six completed in the former with just four getting round in the latter (two of those being remounted – something that is no longer allowed.)The going in 1991 was officially described as good to firm and Mr Frisk’s time of 8 minutes and 49seconds is a record that appears unlikely to be troubled on this occasion.

Sixth in this season’s Welsh National, he is owned by locally based owner, Trevor Hemmings, who is no stranger to success in this race having won it twice with Hedgehunter and Ballabriggs. Vintage Star .The ten-year-old had been something of an underachiever in his career having seemed a smart prospect in his younger days, but he’s looked a different horse this year, finishing third over the National fences in the Becher Chase in December before going on to win races at Musselburgh and Carlisle. Ryan Mania will take the ride.
