Aimee Fuller, Jones's teammate, helped commentate her friend's run from the BBC box and was moved to tears by her triumph.

"She's been a big role model of mine and one of my best mates, so to see what she's done today for British snowboarding is insane," she said afterwards. "I'm overwhelmed by everything and I could not be happier for her."

Jones was surprised by her parents at the finishing line.

"It's absolutely unbelievable, she has never disappointed us," said mum Helen Jones. "We have always been proud of her but, blimey, this is the icing on the cake."

Congratulations quickly flooded in from fellow athletes. "Amazing @jennyjonessnow I was gripped!!" tweeted gold medalist Jess Ennis-Hill. Andy Murray tweeted, "Jenny Jones! Is it wrong to hope everyone left falls?", then adding: "Yesssssssssssssssss!"

Jones celebrated with a glass of champagne saying, "I'd not had any alcohol for six months in preparation for the Olympics. This tastes good."
