Tony McCoy has revealed he will ride Blowing Wind in Saturday's Grand National.

The champion jockey, who on Tuesday broke Sir Gordon Richards' record of 269 winners in a season, has yet to win the event.

But he told BBC Sport Online he planned to overturn that record on the Martin Pipe-trained horse.

He said: "Myself and the boss [Pipe] have talked about it and, with Blowing Wind near enough the joint favourite, it was very hard not to ride him.

"He's a horse with plenty of ability and, to have won at the Cheltenham Festival, it shows he's in good form."

McCoy was unseated in last year's race on Blowing Wind but remounted to finish in third place.

And, despite the horse being just one of four finishers, the Irishman revealed he still had niggling doubts about his chances.

"There is a question over whether he lasts the four miles but I think that's the case with most of the runners," he added.

The Grand National is one of the few races to have eluded McCoy so far and he insisted that he was "more determined than ever" to take the top prize.

On Tuesday, the Irishman broke Richards' record riding Valfonic in the Leek Wooton Novices' Handicap Hurdle, one of three winners at Warwick.

Following his latest accolade, some racing pundits have hailed him as the most complete jockey in the history of the sport.

Unsurprisingly, though, the self-deprecating McCoy disagrees.

He said: "I don't really listen to what people say. I'm just lucky to be fit and healthy.

"You only have to look at Adrian Maguire and Joe Tizzard (currently out with a broken neck and back respectively) to know that it can all change very quickly."

Blowing Wind's odds are expected to shorten for the Grand National after McCoy's announcement.

McCoy and the rest of the jockeys at Aintree's three days of racing will wear black armbands as a mark of respect to the Queen Mother.

There will also be a minute's silence before the runners' parade while bookmakers have confirmed betting shops will be closed on Tuesday, the day of her funeral.
