Mon Mome, the 100-1 winner of the 2009 Grand National has been retired, aged 13.

The gelding, trained by Venetia Williams, will spend his retirement at her Herefordshireyard.

Mon Mome, ridden by Liam Treadwell, became the first 100-1 winner since Foinavon in 1967, and therefore the joint highest priced winner of the race. It was the jockey’s first ride in the race.

He also made Venetia only second woman in the history of the Grand National to train a winner, after Jenny Pitman (Corbiere in 1983 and Royal Athlete 1995).

The French-bred, owned by Vida Bingham, won six from 53 starts, he also finished third in the 2010 Cheltenham Gold Cup. But his Aintree victory was his final win and he was pulled up on his final outing, at Warwick on 10 March.

Clare Balding’s post-race interview with jockey Liam Treadwell attracted complaints to the BBC — after she joked about his bad teeth, urging him to “Give us a big grin”. But Liam had the last laugh — he was inundated with offers of free dental work, and now sports a perfect set of gnashers.
