Knowing which horses to steer clear of in the Grand National is part and parcel of narrowing down the genuine contenders for the race title. This challenge takes on a new slant in 2016 with some top class racehorses entered in the world's toughest stayer's chase and priced amongst the favourites.
Here's our selection of horses to steer clear of in the 2016 Grand National:
Silviniaco Conti was withdrawn from this season's Cheltenham Festival in preference of a run at Aintree. This was a bold move given that he's more accustomed to racing in top class chases over shorter distances. He's the reigning Ascot Chase winner and has won the Betfred Bowl at Aintree previously. However, don't let this fool you. Silviniaco's days of winning races by large margins are behind him, and with no experience at all in races around the four mile mark it's a massive ask for him to find an extra mile to win the Grand National at first attempt.
O'Faolins Boy hasn't quite delivered on the potential he demonstrated when winning the RSA Chase at the 2014 Cheltenham Festival. While he's been run sparingly since then, he's tended to struggle. He achieved a win in Newbury in December but that was sandwiched between two races where he was pulled up, and he's finished outside the top six in his last two races - which included finishing 53 lengths behind Don Cossack in the Cheltenham Gold Cup. Will he show a different side of himself when asked to run an extra mile? Unlikely. In fact indications are he won't pass the finishing post in the 2016 Grand National.
Gilgamboa tends to reserve his best performances for Irish tracks, where he's picked up a Grade 1 chase win over 20 furlongs as well as a Grade 2. His only trips to the UK have been for the Cheltenham Festival, and both have been failures, including a 5th place finish in the Ryanair Chase last time out. There's little in his record to suggest that he's a Grand National winner in the making, as he's tended to struggle the further he's been asked to stay. Considering he'll also be amongst the most heavily weighted horses if he competes, he doesn't look a contender in any way.
Sir Des Champs
Sir Des Champs was one of the top racehorses in Ireland in 2012-13, taking the Jewson Novices Chase at the Cheltenham Festival in 2012 before claiming both the Irish Hennessy and Punchestown Gold Cup in 2013. Rated 173 at his peak, he's dropped down to the 154 mark since coming back from a two year break in 2015. He started his comeback season with a win but has failed to place in either of his races since then, with both of these run over 3 miles. A horse who looks past his best he'll do well to finish the 2016 Grand National.
Without a single win over a distance greater than 21 furlongs, it's hard to imagine how Double Ross will find two more miles in the tank at Aintree. He did manage a place at an Ascot handicap in December, but that's the only one he has achieved in his last 10 races. His low handicap will free him up somewhat, but there's little that suggests he'll be a force in the Grand National.
