The Irish rider was top jockey at the Cheltenham Festival, where she won the Champion Hurdle, and crowned a fabulous season with an historic triumph in the world’s greatest steeplechase.
Blackmore said: “This is the Aintree Grand National. I’m completely blown away.
“I got a fantastic passage the whole way. Minella Times was unbelievable, he jumped fantastic, I don’t think he missed a beat anywhere.
“He was able to travel into a gap, I seemed to have loads of space everywhere and you couldn’t have wished for a better passage. He was just unbelievable, he really was, his jumping was second to none.
“I’m so lucky to be riding these horses for Henry de Bromhead. He trained a one-two there which is incredible. That can’t be forgotten in the whole scheme of things.
“It’s great to win it in these colours, too. It’s always a privilege to ride for JP McManus and to win it for him is unbelievable. They’ve had a tough year so hopefully this can make things a little easier.
“This is a massive deal for me personally, not the fact I’m a female. The thing that hit me when I crossed the line was that I’d won the National, not that I’m the first female to win the National. I’m just delighted.”
