The Rachael Blackmore factor could see Ain't That A Shame go off as favourite for the 2023 Randox Grand National Festival at Aintree Racecourse.
Having been a 25-1 chance ante-post before the Tipperary-born rider had confirmed which horse she would partner in the race at the start of the week, the Henry De Bromhead-trained Ain't That A Shame is now around a 8-1 for glory in the world's greatest steeplechase.
Blackmore, of course, became the first female jockey to win the Aintree showpiece aboard De Bromhead's now-retired Minella Times in 2021. And following more success at last month's Cheltenham Festival and over the first two days at Aintree, Blackmore looks again to be the one punters want in the betting.
