Andrew Newton:, external Thank you BBC Sport for introducing me to snowboarding. Can't believe what I'm seeing.

Leanne: , external Both boys learnt on dry slopes and here they are representing GB...wow!

Peter Capstick: , external Some shocking scores from the judges there, first time ever watched that sport but even I thought the judges weren't great.

From the Rosa Khutor Extreme Park to the slightly less sexily named Laura Cross-country Ski & Biathlon Centre. The women's 15km skiathlon has just started and there is another gold medal at stake. Marit Bjoergen of Norway is the reigning Olympic and world champion.

Billy Morgan on BBC Two after finishing 10th in the slopestyle final: "I just thought go big or go home and it's just didn't work for me. Hopefully I'll get a chance again in four years time."

Jamie Nicholls on BBC Two after finishing sixth in the slopestyle final: "I'm really happy that we both made the final and got a top 10 finish. It's weird because I don't usually fall off the rails, but I'm really proud. The level was so high. If we have the facilities in the UK then maybe we'll see some Brits on the podium in the next one."

Sage Kotsenburg is only 20 years old and from Idaho. His victory is a huge surprise given that he only finished 20th in the 2013 World Championships and 17th the year before. And check this out for cool - Kotsenburg comes from something of a snowboarding dynasty - his brother Blaze and his sister Kirra have both competed professionally as snowboarders.

Staale Sandbech of Norway takes the silver medal, with Canada's Mark McMorris defying a broken rib to win bronze. Jamie Nicholls finishes sixth and Billy Morgan 10th in the first ever men's slopestyle final. Sizzling stuff.

Max Parrot's second run is only good enough for fifth place so Sage Kotsenburg of the USA wins the first gold medal of the Sochi 2014 Winter Olympics.

Staale Sandbech of Norway absolutely nails his run, finishing with a triple spin and celebrating with a Klinsmann dive across the snow. It's a great score of 91.75, but it can't knock Sage Kotsenburg off the top of the podium, with only Max Parrot to go.

"Not a fan on their seats, everyone is standing during the final runs of the men's Olympic snowboard Slopestyle."

How did 20-year-old Jamie Nicholls get started in slopestyle? Here's his biography on the Team GB website: , external

"Jamie started snowboarding when he was seven years old at Halifax Ski and Snowboard centre. By the age of nine, he could already do front flips and backside 900s, and at 13 years old, he was already considered one of the best UK snowboarders.

"Since 2009, Jamie has travelled the globe, competing in Big Air, Slopestyle and Rail contests. His goals are to film good snowboard video parts, get on the cover of snowboard magazines and achieve the podium at the main competitions.

Sven Thorgren glides over the rails and sails over the giant Russian doll in the middle of the course. His arms are aloft. The Swedish flags are flying. Even his rivals are clapping....

...and it's bad news for the Brits as he goes third with 87.50 to knock Great Britain's Jamie Nicholls out of the medal positions.

Seb Toutant of Canada stumbles at the last and is given 58.50. Another of the big hitters is out of the hunt for slopestyle medals.

Six riders to go. Nicholls is still in the bronze medal position with a score of 85.50. Cross everything.

BBC Sport snowboarding and freestyle skiing commentator

"It's almost like sliding off the first ride put Jamie Nicholls off his stride. He's a perfectionist. He's still in the bronze medal position though. We should stop the competition now."

Nicholls slips off the first rail and then trundles down very half-heartedly. It's only a 46.50 this time round, but he remains in the bronze medal position for now.

Bye bye Billy. It's heartbreak for the first of the Britons as he lands on his rear after a triple flip to shatter his chances of a medal. A score of 39.75 leaves him in ninth place in the final.

Leader Sage Kotsenburg - dressed like an astronaut - loses his balance early on and has to settle for an 83.25. But he remains in first place after scoring 93.50 first time round. Next up, the British pair.

Flower Power:, external Woohoo! Go Jamie Nicholls nearly choked on my cornflakes when he landed that last jump!

Tracy Pinder:, external Slopestyle final is gripping - this is making me late for work. Boys in the commentary box delivering brilliant lines.
