Downend snowboarder Jenny Jones has become the first Briton to defend her gold medal at the Winter X Games in Aspen, Colorado.

Jones held off strong competition to claim her second gold medal in the slopestyle event at the invitational games.

Slopestyle is not an Olympic sport, so Jones will not be competing in Vancouver later this month, but the discipline is one of the popular events at the annual event.

Her victory this year trumped her shock win 12 months ago when top boarders Jamie Anderson and Janna Meyen-Weatherby did not compete.

But Jones cemented her status as one of the best snowboarders in the world, racing with a swollen knee to beat her rivals and take the victory with a score of 92.66.

She said: "It feels great, it really does.

"It is a totally different experience this time because my knee was so sore and everything.

"I didn't really think I was going to get anywhere. So I am still a little bit in shock that I came in first."

Slopestyle is a freestyle event where the rider chooses their own course through a series of bumps, rails and jumps and scores are based on difficulty and execution. Jones managed a 540 degrees rotation before a huge final jump to finish three points ahead of American Anderson.
