Eve Muirhead's team of curlers will, of course, be hoping to make amends for their opening round robin defeat by Sweden on Monday.

Skip Muirhead was off her game in that 6-4 defeat, with a shot accuracy of 61% whereas Sweden skip Margaretha Sigfridsson was higher at 80%.

"It is always disappointing to lose the first match. It was always going to be a tough one anyway, playing the European champions and world runners-up," said Muirhead.

"They are one of the favourites but the game could have gone either way."

Britain's women curling team will take to the ice at around 1506 GMT this afternoon for their round robin match with USA, but that does not mean it's been all quiet on the curling front. And there's good news for Eve Muirhead and co, too, because defending champions Sweden lost 9-3 to Canada. Switzerland, Russia and South Korea also recorded victories.

It's official. Katie Summerhayes has qualified for the final of the women's ski slopestyle in third place. The Briton was the only competitor to score above 80 in both runs and only Canadian pair Dara Howell and Kim Lamarre qualified ahead of her.

Britain's Katie Summerhayes absolutely delighted with her scores in qualification. 84.00 in the heat was impressive and there is still a lot of improvements she can make.

"I was really nervous this morning but I have tried to just think of it as a normal competition," she tells BBC Sport.

"I have another move I'm going to try in the final so we'll see what I can do with that - I'm definitely going for it [a medal]."

For those of you who don't know much about Katie Summerhayes then I can help there. Last season, the 18-year-old won the first World Cup skiing medal by a British female in 19 years when she secured silver. And, apparently, the Sheffield teenager was so star struck when she met Olympic heptathlon champion Jessica Ennis she ran off.

"Katie is happy with that run - a smile is never far away from her face. She was rewarded for good rail technicality and although the score doesn't move her up the standings it is better than her first run and moves her closer to the Canadians."

Katie Summerhayes improved on her first run and was awarded 84.00 points for her second run, which leaves her sitting pretty in third place. The final will start at 0900 GMT.

Union flags are being waved and Katie Summerhayes is smiling broadly after a drama-free second run. The Brit is waiting for the judges to cast their scores.

Thanks to the misjudgement, or ill fortune of others, Katie Summerhayes has qualified for the final of the women's ski slopestyle before her second run. Canadians Dara Howell, Kim Lamarre and Yuki Tsubota, as well as America's Devin Logan, have also gone through. The top 12 will contest the final.

Katie Summerhayes is trying to follow in the footsteps of fellow slopestyler Jenny Jones and win Britain's second medal on snow, and she was at the front of the queue to congratulate her team-mate on that historic snowboard bronze on Sunday, posting the evidence on Twitter., external

Can Great Britain's Katie Summerhayes add to Team GB's medal collection today?

It's overcast here in the Sochi mountains which GB skiing performance director Paddy Mortimer tells me is good for Summerhayes' prospects.

"It's like being at a snowdome in Manchester, or anywhere in the UK," he tells BBC Sport. "This will help her as it's what she is used to - those skiers who grew up on real snow won't like it as they are used to training in the sun."

Katie Summerhayes remains in third and still has a second run in her locker. The 18-year-old suffered a career-threatening knee injury a few years ago and her build up to Sochi was disrupted by injury, with the Sheffield teenager suffering complications from that original knee problem. Nevertheless, Summerhayes is on course to reach the Olympic final, which is good, isn't it.

For those of you who prefer the fourth day of the Winter Olympics to look more like a military operation, then I can assist there. Set your alarms, make sure that stopwatch is working, because this his how the first bit of the day will unfold. (Brits in brackets and all times GMT)

"That's Slopestyle for you!

"Two big pre-event medal favourites - World champion Kaya Turski of Canada and German World Cup leader Lisa Zimmerman - both crash on their first run and must deliver in the second in order to reach the final later today.

"GB's Katie Summerhayes admitted she was nervous ahead of today's qualifiers but has shrugged that off and is third in the standings after the first run.

"I'm 99.9% certain her score of 81.40 will already be enough to progress."

Qualification for the women's ski slopestyle is under way and plenty have tumbled into the snow. Britain's Katie Summerhayes has been and gone and looks likely to progress. She is currently third (81.40) after her first run with the top 12 to go through to the final later this morning.

And there's curling of course. There'll always be curling and Britain's men and women are in action today.

Today cometh the rock star, the world's best known snowboarder, a man famous enough to make cameos in Hollywood movies and adorn the cover of Rolling Stone., external Can Shaun White become the first American man to win three consecutive Winter Olympic titles? Today is the day we find out. It's time to prepare to McTwist and shout.
