Grand National, Aintree, Tomorrow, 4.15, Free £20 bet

The Spoiler’s pick for tomorrow’s Grand National is Darkness. We didn’t pick him because he’s named after our least favourite spandex-wearing cheese rockers - check out our statistical approach here.

If you enjoy a good flutter, then you should back him with Boylesports. Place £10 on him (or any other nag) and they will give you a free £20 bet to play with. Our advice would be to stick that £20 on a football outcome with short odds (like a Manchetser Utd or Arsenal win this weekend) as a means of insurance. Sound like a plan? Then place your bets here.

Already have a Boylesports account? Then back Darkness with Bet365, who are offering a £200 Free Bet Basket, or Paddy Power, who offer a free matched bet of up to £25. Both firms are also paying each-way on five places.

Don’t resort to picking names out of hats or playing a game of pin the tail on the form guide: our friends at chickendinner have come up with a foolproof plan to identify this year’s Grand National winner. They eliminated all the likely losers who don’t fit the profile of a champion until we were left with just one horse standing. Read on to find out who it was:

14 of the last 17 winners started in the top eight of the betting. Therefore it must be one of these guys (three are joint-eighth):

Step Two
10 of the last 13 winners have been aged either 9 or 10. That means we say goodbye to Rambling Minister (11), Hear The Echo (8), Parsons Legacy (11) and Irish Invader (8). Still fighting are:
