Rachael Blackmore, the first female jockey to win the Grand National when successful on Minella Times three years ago, will be aboard 2021 Cheltenham Gold Cup winner Minella Indo for trainer Henry de Bromhead.
Minella Indo would be only the third horse, and the first since L’Escargot in 1975, to complete the Gold Cup-National double.
She is one of three women riding in the race, with Gina Andrews partnering Latenightpass for her husband Tom Ellis, while Lucy Turner rides the Venetia Williams-trained Chambard.
Turner is one of two amateur jockeys competing alongside David Maxwell, who bought Ain’t That A Shame – 17th in the National last year – so he could have a ride in the contest.
Irish trainers have developed a stranglehold on big jump races, winning 18 of the 27 contests at the Cheltenham Festival.
After Cheltenham, British Horseracing Authority chief executive Julie Harrington said the domination was “damaging” the sport and said more needed to be done to encourage the top horses to be bred, owned, trained and raced in Britain.
