Mikaela Shiffrin has two ugly DNF marks by her name so far at the Winter Olympics, but it could be third time lucky for the American on Friday.

The 26-year-old took home one gold medal from both the 2014 Sochi Games and 2018 in Pyeongchang, and came to Beijing with high hopes of adding to that haul.

Ester Ledecka is among the rivals who will also be targeting the super-G podium, while other multiple champions in action elsewhere on Friday include Shaun White and Dario Cologna.

Here, Stats Perform previews each of the day's medal events. 

Alpine skiing

Shiffrin took super-G gold at the 2019 World Championships, so she cannot be counted out here, providing she cuts out the errors and finishes the course.

Italians Federica Brignone, Elena Curtoni and Sofia Goggia are 1-2-3 in the World Cup standings, so should be factors, while Czech star Ledecka is chasing a second extraordinary double. She took snowboard parallel giant slalom gold earlier in the Games, and after winning both that and the super-G in 2018, she cannot be ruled out.

Switzerland's Lara Gut-Behrami won the world title last year and sits fifth in the World Cup standings, but a reigning world champion has never won gold in the women's Olympic super-G.

Biathlon

Can Norway's Marte Olsbu Roeiseland upgrade from silver four years ago in the women's 7.5km sprint? Her World Cup form has been good, with two wins in the sprints, so gold is a realistic aim. She already has one gold from Beijing, in the team relay, and a bronze from the 15km individual.

Norway's Tiril Eckhoff has not shown her best form in the World Cup this year, but Roeiseland's compatriot is the reigning world champion, a two-time Olympic relay gold medallist, and could come into the equation.

Cross-country skiing

Johannes Hoesflot Klaebo won gold in the sprint and should again be a factor in Friday's men's 15km classic, but the Norwegian says Finland's Iivo Niskanen is the hottest prospect for top of the podium. 

"He's definitely the favourite I would say, together with [Alexander] Bolshunov," said Klaebo. "All of us need to have the best day we can have, and it will be tough but we're just going to give it all and hopefully manage to have a good day and to have good skis and everything and then for sure it's possible."

Swiss veteran Cologna has won this event in the last three Olympics, but a four-peat seems an unlikely prospect.

Short track speed skating

Netherlands' Suzanne Schulting competes in the women's 1,000m, looking to defend the title, which has not been achieved since Lee-kyung Chun did so in 1998. South Korea and China have won 16 of the 21 medals in this event since its Olympic debut in 1994.

Skeleton

Christopher Grotheer was star of the show as the men's skeleton began on Thursday, leading by 0.70 seconds after two runs. That is a significant gap, with the German's closest rival being his compatriot Alex Jungk.

World champion Grotheer said: "The first run was brilliant, and the second run was also really good. I have a really good first day and I hope [on Friday] I can show this performance too."

Snowboard

American White heads into the halfpipe knowing this will be his career swan song, having decided to retire. Three times a gold medallist, the 35-year-old is bidding to become the first man to win individual gold medals at four Winter Olympics.

White was fourth in qualifying, with Japan's Ayumu Hirano leading the way.

Speed skating

Sweden's Nils van der Poel has made his mark on and off the rink in Beijing, winning gold in the men's 5,000m before making a raft of accusations, claiming the dominant Netherlands team have unduly influenced racing conditions. He goes again on Friday in the men's 10,000m and is the likely champion.
