A new £500,000 bonus will be on offer for any horse that wins one of three designated trials before following up with victory in the Randox Grand National.
William Hill is sponsoring three established warm-ups for the famous handicap, the Becher Chase at Aintree, the Classic Chase at Warwick and the Grand National Trial at Haydock
The connections of any horse who can win one of those contests and then go on to take the Grand National itself will receive a £500,000 bonus on top of the existing prize-money – taking the full winning prize-fund at Aintree in April to £1m in total.
Dickon White, regional director north west at the Jockey Club, said: "We're delighted to be supporting William Hill with this fantastic initiative in the build up to the Randox Grand National.
"The introduction of the William Hill Half A Mill will generate a real excitement throughout the season and we hope to incentivise some of the leading Grand National contenders to try out their credentials in one of the three qualifying races."
