William Hill's spokesman Ben Clarke added: "Its a very competitive renewal of a race that has unearthed some very classy horses in the past with recent winners Noland, Monsignor and French Holly all having gone on to win at the festival. The front three in this years betting have all impressed recently and I wouldn't be surprised to see any of them develop into genuine Cheltenham contenders."
