Fair play to our man from Tonga. It worked in Rio, so why not do it again.

It was one of the most memorable moments of the opening ceremony of the 2016 Olympics - a bare-chested and oiled up Pita Taufatofua of Tonga in a native outfit.

Well, he's back. He will swap the taekwondo mat for cross-country skis to become one of the most unlikely double Olympians of all time.

Taufatofua, 34, had not seen snow until a couple of years ago, and following his Rio exposure he had acting offers from Hollywood and potential modelling deals.

However, he was motivated by a desire to find his "next big challenge" in something "completely impossible". Cue an attempt to qualify for Pyeongchang in cross-country skiing - something he managed in the final qualification race in Iceland last month.

"Every time I ski I feel like I die a little inside," he says. "The burn starts and you hold the burn for an hour or more. I haven't had a race where I felt completely happy in terms of no pain."

He had no shirt on during the 2014 Rio Olympics, he has done the same again. He must be freezing.

The journalists near me have resorted to dancing to keep warm. Well, if you can't beat them...

Pretty decent collection of Olympic swag to keep spectators warm tonight! A padded mat for your bum, a blanket, an overcoat, a hat, heating pads, a ‘traditional’ tambourine like Korean instrument, free coffee & a mini torch that lights up!

Talking of great stories...

Nineteen-year-old alpine skier Sabrina Simader will become only Kenya's second Winter Olympian in Pyeongchang.

Typically, when skiers from smaller nations compete at the Winter Games they do so in the 'safer' technical events of slalom or giant slalom.

Not so for Simader. Born in Kenya but raised in Austria, she skis in speed events such as the super-G, where competitors regular top 60mph.

"At the beginning, people looked at me. OK, a black skier always gets looked at - but when your performances get better and you improve, you win them over," she said in January.

She has had to rely on sponsors and crowdfunding to get her to South Korea and now here she is, holding her country's flag proudly.

Canadian slopestyle snowboarder Spencer O'Brien, one of the favourites to win gold in Pyeongchang, describes her struggle with rheumatoid arthritis ahead of the 2014 Sochi Games.

Throughout these Games we will hear of incredibly motivating stories - and Canadian four-time Olympic speed skating medallist Denny Morrison has an incredible tale to tell.

In the last three years he has suffered a motorcycle crash and a stroke but still managed to qualify for the 2018 Winter Olympics.

"People ask me 'why are you doing this, you have the perfect reason to retire'," said the 32-year-old.

"I've spent my life telling people if you follow your dreams, work hard and overcome adversity you could go to the Olympics. Then I faced true adversity with the motorcycle crash and the broken leg, the punctured lung, the concussion, broken everything, so it's time to walk the walk and not just talk the talk.

"Physically the very lowest moment was in the hospital bed shortly after, within 48 hours of the crash, I had the hiccups. Every hiccup, every five, ten seconds I felt a jolt of pain through my whole body but my spirit never broke."

Morrison and the rest of the 226-strong team are expected to do well over the next two weeks.

Watch the incredible interview with Morrison below.

Gemma Bailey: Wow Bermuda. You would think they would wear proper coats rather than blazers!! All that training to possibly waste with a serious cold!! All for the shorts but really the blazer!!

Members of the Czech delegation wanted to “sample life with the fans” tonight, so took a local bus to the stadium rather than their official transport. “It’s just amazing” they say.

Amazing it is. Now they are in the arena, which is even more amazing.

The Olympic athletes from Russia emerged under the Olympic flag to a mixed chorus of jeers and cheers.

It’s not the kind of weather the Jamaicans are used to, but bobsleigh trio Jazmin Fenlator, Carrie Russell and Audra Segree will be marching with purpose at the opening ceremony.

They’re the nation’s first ever female Olympic bobsleigh team and will make their debuts 30 years after the 'Cool Running' men made their legendary bow at Calgary 1988.

“We’re proud to represent Jamaica and represent women here in Pyeongchang,” says pilot Fenlator.

Jamaica are the 63rd team to walk out into the arena. Will their story have a Hollywood ending?

Number 62. Come on down, Japan.

Japan's Ayumu Hirano, 19, is hoping to go one step better than his silver medal in the 2014 Sochi Olympics, which he achieved at the age of 15, by taking the gold in the snowboard halfpipe event.

"I have been training for the past four years so that I can get a gold," says the teenager. "If I can throw down the best run I can do I am confident I can get the gold."

Their inclusion is a controversial one after Russia was banned. But individual athletes were not and they will be competing under the banner of "Olympic Athlete from Russia". They walk in under the Olympic flag, as they are banned from having any Russian flags or any indication of their national colours.

That's one way to embrace the cold.

The Bermuda team bravely wear shorts despite the cold conditions at the opening ceremony.

None of the short track speed skaters are at the Olympic Stadium for the ceremony, as their first qualification event in the women's 500m is on Saturday (10:44 GMT).

Elise Christie, the reigning world champion, is competing at her third Games and will be watching from her base in the athletes' village.

"It's a shame because it's the first one I've not been to," said the 27-year-old Scot.

"But there will be plenty of other Team GB people out there representing us."

Great Britain bobsleighers Mica McNeill and Mica Moore find out how well they really know each other before the Winter Olympics in Pyeongchang.

You have to have some nerves (and incredible skill) to do twists, jumps and somersaults on a snowboard or skis while worrying about the impending disaster coming if you land badly.

But what if you were guaranteed a safe landing?

Watch below as Ski Sunday's Jenny Jones tries out Team GB's secret weapon, a "giant bouncy castle".

The 60-metre long and 23-metre wide airbag is the biggest of its kind in the world and cost around £100,000 of UK Sport and Sport England money. UK Sport say it enables athletes to "be far more experimental without fear of crashing out on landing".

Go on, admit it. It looks fantastic fun.

And here come Great Britain, with 2014 gold medallist Lizzy Yarnold with a massive smile on her face as she waves the flag and leads the team into the stadium.

Britain have never won more than four medals at a single Games, can they do that this time around?

The five-person team of Ireland are the 45th team into the stadium. Their flag-bearer is snowboarder Seamus O'Connor.

Some sports that we will see over the next two weeks you may well think 'that looks fun, I'd like a go at that'. Then there is the ski jump.

Meet Peter Prevc, the first ski jumper to jump over 250m, who has the expectations of Slovenia on his shoulders and admits you have to be "crazy" to do his sport.

"When all the pieces came together and I jumped 250m it was just amazing it is a new thing in history but when you are in the air it doesn't seem so far," he says.

"They say that ski jumpers are crazy, we just jump into nowhere, into the air, but when you make a good jump you are flushed with adrenaline."

Slovenia are the 40th nation to come into the arena. Great Britain are 52nd.

Watch (with awe) the interview below.
