Ain't That A Shame has surged to the top of the market for Saturday's Aintree spectacular, as bettors are backing Rachael Blackmore to win her second Randox Grand National.
When Blackmore led Minella Times to victory in the four-and-a-half-mile marathon two years ago, she made history by being the first woman to ride the victor.
Like Minella Times, Ain’t That A Shame is trained by Henry de Bromhead.
