Punters pile into Blackmore's Grand National mount Ain't That A Shame

Punters are backing Rachael Blackmore to land a second Randox Grand National, with her mount Ain't That A Shame rocketing to the top echelons of the market for Saturday’s Aintree showpiece.

Blackmore created history two years ago when steering Minella Times to victory, becoming the first woman to ride the winner of the four-and-a-quarter-mile marathon.

Having been as long as 16-1 with some firms on Friday morning, he halved in price by the afternoon.

And Blackmore feels he has the right credentials to run a big race in the National.

"Ain’t That A Shame has a lovely profile for the race," she told her Betfair blog.

"He was unlucky to be just beaten in the Munster National at Limerick in October, and it wasn’t my best day in the saddle when I finished fourth on him in the Paddy Power Chase at Leopardstown over Christmas.

"But he won nicely at Gowran the last day, and it was no harm that the runner-up came out and won at Fairyhouse there at the weekend.

"He travels well through his races, which is a big help. You’re just hoping that you can get into a nice position and find a nice racing rhythm over the first few fences. I am hopeful that he can.

"After that, you never know, it’s the Grand National, but he has his chance and I’m very much
