Day 7 of the 2022 Beijing Winter Olympics

The Netherlands' Suzanne Schulting has won back-to-back women's 1,000m short track speed skating gold medals — by the thinnest of margins.

The 24-year-old defended the title she won at the PyeongChang Games four years ago by the slimmest of margins, pipping Korea's Choi Min-jeong at the finish line by just 0.052 seconds to win in 1:28.391.

"For the Netherlands, it means a lot," Schulting said.

"I worked so hard for the whole team. I got the gold, but I got the gold for the whole team, and I am super proud."

Schulting arrived in the final in blistering form and brimming with confidence after breaking the world record in the quarterfinal with a time of 1:26.514.

"I became really confident out there after skating a world record. I was really excited," she said.

"I was focusing on what I had to do and on my technique and everything. It's insane."

A nail-biting finish capped an already dramatic race, with legendary Italian speed skater Arianna Fontana — a 10-time Olympic medalist — crashing out as the skaters rounded for their final lap.

Fontana had taken gold ahead of Schulting in the 500m final on Monday to defend her own title from PyeongChang 2018 but saw her hopes for a second gold slide away in the 1,000m.

Having taken out Kristen Santos of the US in the process, the Italian received a penalty and did not finish.

Nicknamed the 'Queen of Korean Short Track,' according to the Olympic website, Choi's silver adds to the two gold medals she won in her home nation in 2018.

Debuting at her first Olympics, Belgium's Hanne Desmet took bronze, with Schulting quick to congratulate her friend and training partner.

"I am super proud of Hanne," Schulting said.

"We train together and we're friends. It makes it even more special."

Norwegian biathlete Marte Olsbu Røiseland triumphed in the women's 7.5km sprint to win her second gold medal of Beijing 2022.

The 31-year-old finished in 20:44.3 to become the first Norwegian woman to win the event, adding to her gold in 4x6km mixed relay on Saturday and her bronze in the 15km individual on Monday.

Sweden's Elvira Öberg won silver — a first Olympic medal for the 22-year-old — in a race that also featured her sister Hanna, who finished 19th.

Italy's Dorothea Wierer completed the podium by winning bronze.

After taking silver in the 7.5km sprint and mixed relay in Pyeongchang four years ago, Røiseland has now gone one better in both at Beijing.

"It feels great. This is my best performance ever and I did it today," Røiseland told reporters.

"This year, I have enjoyed biathlon even more. I am smiling and having fun. I just feel so lucky that I'm here and that I can race good races. I'm just enjoying it."

Røiseland revealed she was "disappointed" with her finish in Monday's 15km event — won by Germany's Denise Herrmann — but emphatically banished any lingering regrets in the sprint with a composed display of sharpshooting at the Zhangjiakou National Biathlon Centre.

"I was a bit disappointed because I missed the last shots, so I have worked a lot for three days now to try to focus on today and forget about the last race," Røiseland said.

"I think I did a really good job in my head before today's race and, for that, I'm really happy."

If you're going to throw yourself head-first down an icy track at speeds of over 100km/h, you might as well look good doing it.

Competitors for the skeleton event at Beijing 2022 have been doing just that as they get creative with their helmet designs.

From colorful parrots to patriotic eagles, it seems there is no artwork too imaginative for the track.

Helmets in the skeleton are certainly a necessity, as participants balance on small sleds and hurtle down a narrow track.

Athletes compete on the same course across two days, getting four runs each. The competitor with the fastest combined time wins the event.

But perhaps the real winner is one of these rather colorful helmets...

Finland's Iivo Niskanen captured cross-country skiing gold in the men's 15km classic event on Friday, winning by 23.2 seconds ahead of the Russian Olympic Committee's Alexander Bolshunov.

Norway's Johannes Høsflot Klæbo took the bronze medal.

After the event, Niskanen made clear that he has been waiting for this opportunity for the past eight years.

"I was fourth, 0.2 seconds behind the medal in Sochi (2014), at this distance, and it's been a long eight years to wait for this race again in the Olympic program.

"Now I managed to win it. I have been focusing on it all the time. This is a really big victory for me."

This is the third Olympic gold medal for the 30-year-old Finnish skier and another win in the bag for the Niskanen family, as his elder sister, Kerttu Niskanen, won the silver medal for the women’s 10km classic event on Thursday.

Featuring balletic techniques and acrobatic skills, the International Ski Federation (FIS) first recognized freestyle skiing as a discipline in 1979.

Athletes ski in a motion that is similar to skating. They perform technically challenging moves during their runs and are scored on different aspects of their performance, depending on the competition they're participating in.

In the aerials events, slopestyle, moguls and halfpipe, judges score competitors based on the finesse of their tricks and the form of their runs.

However, athletes in the big air are judged by the distance and height of their jumps. As for the ski cross, the competition is a timed event — so the athlete who traverses the finish line first takes gold.

Freestyle skiing made its debut as a demonstration sport at the Winter Games in 1988 in Calgary, Canada, and was given medal status at the 1992 Winter Olympics in Albertville, France.

Eileen Gu, who elected to represent her mother's native China over the USA, has been the poster child for these Games and was arguably the biggest name participating in freestyle skiing.

Competing under immense pressure, the 18-year-old wasn't fazed in the slightest and won gold in the women's big air final to delight of the home fans at Beijing 2022.

Gu's victory was so popular in China that fans temporarily crashed the country's leading social media platform, as tens of millions rushed online to celebrate the teenage sensation winning her first gold medal.

Sweden's Nils van der Poel smashed his own world record in the men’s 10,000m speedskating event to secure his second gold medal of the Beijing Olympics on Friday.

Van der Poel’s time of 12:30.74, was over two seconds faster than the previous mark he set last February at the World Championships in the Netherlands. 

After the race, van Der Poel said, "Going in, I thought I should be set to beat second. I was sticking to going after that. Technically, I didn’t have my best race, but physically, I am in great shape.

"I didn’t want to risk going too hard too early. With five laps to go, I felt like the world record was in reach, so I just went for that.

"I am very satisfied. This was the main goal when I started three years ago. It turned out a lot better than I could have ever imagined."

With the victory, the Swede became the first men’s speed skater to win the 5,000m and the 10,000m events at the same Winter Games since Dutch speed skater Jochem Uytdehaage in 2002. 

Patrick Roest of the Netherlands finished with a time of 12:44.59 — 13.85 seconds behind the Swede — to win the silver medal. Italy’s Davide Ghiotto notched a time of 12:45.98 to claim the bronze. 

The gold medal is the fifth for Sweden, which now sits one behind Norway and Germany’s six on the Olympic medal table.

The World Anti-Doping Agency (WADA) announced Friday it will lodge an appeal to the Court of Arbitration for Sport (CAS) in relation to the Russian Anti-Doping Agency’s (RUSADA) decision to lift a provisional suspension on figure skater Kamila Valieva following a doping violation.

WADA did not name Valieva in their statement, instead referring to “a Russian Olympic Committee figure skater.”

Per WADA’s Anti-Doping Code, doping violations involving adult athletes carry a mandatory public disclosure. Minors involved in doping cases (anyone under the age of 18) are considered “protected persons,” meaning their identity doesn't have to be disclosed publicly.

WADA confirmed that a sample was collected in competition by RUSADA on December 25, 2021 before being transported to the WADA-accredited laboratory in Stockholm for analysis.

“On 7 February, the laboratory reported that the sample had returned an Adverse Analytical Finding for the non-specified prohibited substance, trimetazidine,” WADA said in a statement.

“Accordingly, the athlete was notified by RUSADA on 8 February and provisionally suspended, effective immediately.

“Following a hearing on 9 February, the RUSADA Disciplinary Committee decided to lift the athlete’s provisional suspension, allowing her to resume participation in the Games.

“Under the terms of the World Anti-Doping Code (Code), WADA has a right to appeal the decision to lift the provisional suspension before CAS and intends to do so on the grounds that the Code has not been correctly applied in this case,” the statement concluded.

American ice skater Nathan Chen won his first Olympic gold medal on Thursday, with a flawless performance in the men's single skating competition.

Chen, who had been the favorite going into the event, became the first American since Evan Lysacek in 2010 to win a men's figure skating gold medal.

After collecting his medal, he told CNN Sport that the victory was "hard to put into words" and the culmination of years of hard work.

After clinching a bronze medal in the women's super-G on Friday, alpine skier Michelle Gisin revealed she had found an unlikely source of inspiration for her journey to the podium.

Last summer, the Swiss athlete — the Olympic combined champion from PyeongChang 2018 — had been hit hard by a bout of mononucleosis and began to fear her chances of participating at Beijing 2022 were over.

"I was struggling so hard, I almost couldn't make it up the stairs all day long," Gisin told the Beijing 2022 website. "I went downstairs once and then sat on the couch all day." 

But it was during one of those days spent on the sofa watching the Tokyo 2020 Olympic Games that Gisin's outlook began to improve.

There were a number of athletes that she began to draw inspiration from, but there was one in particular who stood out: Italian swimmer Gregorio Paltrinieri.

"There was this Italian swimmer that also had mono a couple of months and weeks before and he got bronze in the 10km open water," Gisin said of Paltrinieri, who also won silver in the men's 800m freestyle in Tokyo.

"That was so amazing to see. It meant so much to me to see him compete because I was really deep, deep down in the hole and to see him achieve this gave me a lot of hope."

Italian Olympic skier Luca De Aliprandini, Gisin's boyfriend, got in touch with Paltrinieri and the swimmer was more than happy to offer his advice on coming back from mono.

"It's just way too beautiful that it all worked out," a delighted Gisin said.
