This grade 1, 3 mile event usually throws up some promising novice stayers. BIRCHDALE could be one of those horses for the Nicky Henderson yard. He comes here unbeaten and one of those wins was here at Cheltenham. He looks highly progressive and his previous course win will give him a confidence and experience edge over a lot of the other horses in this field. 10/1 looks a big price for this potentially talented horse.
