Katie Walsh has revealed her desire to become the first female jockey to win the Grand National later today.

Walsh finished third on Seabass last year and she will mount the 10-year-old again this afternoon in her bid to make history.

"I feel he will improve for his run in the Bobbyjo," she said. "If I get the same spin as last year I'd be absolutely delighted. He is a year older and hopefully he is a bit better."

Walsh's brother, Ruby, is also taking part in the race and will be on board favourite On His Own.
