Here is some pretty good research for all the punters out there...
Good luck! 8)
Trends from the last decade for the big race, are as follows:
* Aged between 8 and 12, ten winners in last ten runnings
* Ran at least ten times over fences, 10/10
* Officially rated at least 136, 10/10
* Carried less than 10st 13lb, 10/10
* Won over at least 3m, 10/10
* Achieved a chase Racing Post Rating of at least 142, 10/10
* Between four and six runs since the start of August, 10/10
* Won Class A or B chase, 10/10 (eight at Class A level)
* Ran in the past 42 days, 10/10
* Running in National for the first time, 7/10
Out of the 40 left in only four tick all 10 boxes: Lord of Illusion, Joe's Edge, Ballycassidy, Nil Desperandum.
Then there are eight that tick almost all: Innox, Silver Birch, Clan Royal, Juveigneur, Garvivonnian, Jack High, Baron Windrush and Heros Collonge.
Another influential stat is that seven of the last 10 winners had run over the National fences, three of them winning or finishing in the frame. That favours Nil Desperandum, Innox, Silver Birch, Clan Royal, Garvivonnian and Heros Collonge.
Ballycassidy and Juveigneur have both tried these fences but ran too badly to be true so they're off the list.
In last year's race Nil Desperandum seemed to stay better than Heros Collonge and Innox, and is carrying 4lbs less with arguably a better prep. Innox looks stronger this year but is carrying 7lbs more (plus no Frenchie has won in the last decade) while Heros Collonge carries 4lbs less.
Clan Royal could piss this race but at 5s is unbackable. I haven't even mentioned Hedgehunter because he can't win under 11-12 and he's 8s with me. Lay of the day as far as I'm concerned. Nothing carrying above 11st looks to have a chance.
Horses to back look like Nil Desperandum at 40s, Silver Birch at 25s (praying for a return to form), Garvivonnian at 22s and either Joe's Edge (25s) or Jack High (16s).
Looks like it'll go to the Irish boys like all the big NH races do these days.
