Sky Bet are Non-Runner No Bet on the Randox Health Grand National at Aintree

The Leeds-based firm already have the Non-Runner No Bet concession in place for all races at the Cheltenham Festival and now punters can back their Aintree fancy in the safe knowledge that they will get their money back if the selection doesn't line up in the April showpiece.

Blaklion heads the market at 10/1 following his smooth win in the Becher Chase over the famous fences in December, having previously finished fourth in last year's National. Cause Of Causes (20/1), runner-up to One For Arthur, is another from the class of 2017 towards the head of the market.

The Willie Mullins-trained Total Recall (12/1) is the leading Irish fancy following wins at Newbury and Leopardstown while Definitly Red (16/1) is towards the top of the market for Yorkshire trainer Brian Ellison.

Sky Bet Racing PR Manager Michael Shinners said: "The release of the Grand National weights is always eagerly-anticipated and now Sky Bet punters can place their bets on the great race knowing they will get their money back if their horse doesn't line-up.

"As ever it looks a fiercely competitive renewal and while Blaklion and Total Recall have been popular so far, there will be plenty more movers between now and the tapes going up at Aintree."
