2009 Cheltenham Gold Cup

The 2009 Cheltenham Gold Cup was a horse race which took place at Cheltenham on Friday March 13, 2009. It was the 81st running of the Cheltenham Gold Cup, and it was won by the pre-race favourite Kauto Star. The winner was ridden by Ruby Walsh and trained by Paul Nicholls.
