"Monster method air to kick off for GB's Ben Kilner and a pretty solid first run in snowboard halfpipe. A bit of a hand down on his last landing cost him and he scores a 43 to place 6th. Bit surprising, but encouraging signs. 'Kildog' - his pilot name if he was in Top Gun, apparently - was 18th in Vancouver."

Katie Summerhayes has vowed to "come back stronger" at the next Olympics, which will be held in South Korea.

"We set out to inspire and make people want to go the sport, make people fall in love with it and hopefully we, as a team, have done that," she says.

"I was just thinking this is the most important day of my life, and it's alright I'm lucky to be skiing everyday as my job. My friends are at college.

"That's my goal [to go to another Olympic Games]. I wanted to win a medal but I'll take this experience and come back stronger."

"I think I was scored correctly [in the second run] I made two massive mistakes and it's my fault really my run wasn't clean," a disappointed Katie Summerhayes told BBC Radio 5 Live.

"It's alright [the result] but I skied better in qualifying. I got to the final and that was the target, so that's something I suppose.

"The first run I was chilled and ready to go and the second run felt better, but I knew if I did a good run I'd get a medal so tried to keep calm, but I'm disappointed."

"The women have completed their third and fourth official training runs in the skeleton at Sanki Sliding Centre and Britain's Lizzy Yarnold topped the timings in both, which is boding well for her bid to emulate Amy Williams and win gold. Teammate Shelley Rudman is still struggling to figure out the track and was down in 13th and 14th place. Interesting Noelle Pikus-Pace, the American who finished second in the World Cup standings to Yarnold, did not train today. The Russians, who have had hundreds of practice runs on the track, are also performing well."

I've just wiped the dust off the halfpipe rule book and what I've learnt is, basically, the riders are judged on the overall impression of their run, including amplitude (how high they jump), the difficulty, variety and execution of their tricks and landing. I hope that helps.

Shaun White will do his stuff in the second heat so we won't see the great American in action for some time. There are Brits taking part in the first heat, however, and they are Ben Kilner and Dominic Harington.

"Will the real Arthur Longo please stand Up? A slightly confusing start to the halfpipe contest. We were all led to believe the first rider was France's Arthur Longo. He didn't appear to be that good - he just did some straightforward jumps. Pretty ordinary for this level. Turns out it was a forerunner. The real Arthur Longo was, in fact, excellent."

We will now turn our attention to the men's halfpipe and there have been concerns about the course all morning. Workers have been pumping artificial snow onto it all morning but we seem set to go, go, go.

Katie Summerhayes had spoken about being inspired by Jenny Jones' historic Olympic snowboard slopestyle bronze medal ahead of her own event and she was certainly galvanized during qualifying.

She said she would not play it safe in the final, promising to "go for it" with a more difficult routine, and the teenager certainly stuck to her guns. She will probably leave Sochi with no regrets and that, ultimately, is all an athlete can do.

"The snowboarders had the better conditions. The warm weather has certainly not helped these women competing here today and the only really fantastic run we saw was Dara Howell's."

Katie Summerhayes was pushed to seventh and that faceplant in the first run proved to be very costly indeed. Should the Brit have been a tad more pragmatic on the first run? Maybe, but maybe not. We'll never know. She improved on the second run though and was awarded 70.60 for her efforts.

Teenager Dara Howell celebrates with the two other ladies who will join her on the podium, and they are silver medallist Devin Logan (85.40) of America and Howell's compatriot, Kim Lamarre, who took bronze.

"Ladies and gentleman, here is your Olympic gold medallist - a 19-year-old from Ontario in Canada, Dara Howell. It's a clean sweep on the podium for the North Americans."

The second run was merely a lap of honour for Dara Howell as her amazing 94.20 first run had already secured her the gold.

Emily Chambers:, external Great effort from Katie Summerhayes. Shame no medal but cracking performance, I think I'm obsessed with Sochi.

Joshua Parkinson:, external She went big but the judges scored low. Unlucky Katie Summerhayes, still one for the future.

A triumphant shriek from Kim Lamarre because she has nicked the bronze from Australia's Anna Segal with a 85.00 second run.

"She just had to stick it on her first run. The second run is so much harder. It came down to her not landing that first run."

"Oh no! 70.60. It's not enough, and the hand drags have cost her there, they really have. But you know what? She's 18 and will be 22 in South Korea. Summerhayes is going to feel robbed, but she has done herself and British sport proud."

Katie Summerhayes will not be leaving Sochi with a medal as she is only awarded 70.60 for that second run and that's only good enough for sixth. It was the 'hand drags' which apparently proved costly.
