The United States is hopeful it will be a big day on the ice and ski slope, luge fans get an added treat and the male figure skaters show off their short programs.
Men's figure skating
Russian fans will need to make sure they are at the Iceberg early. Evgeni Plushenko is seventh on the start list for the men's short program.
Skaters worry that going near the beginning will mean a lower score. He'll have to wait through 23 more skaters to see where he stacks up.
Most of the favorites -- Patrick Chan of Canada, Javier Fernandez of Spain and Yuzuru Hanyu of Japan -- are much later in the program.
Chan is still a favorite in the event, as you would expect a three-time running world champion would be. But he was only third in the short program for the team competition, and longtime USA Today Olympics writer Christine Brennan said Chan has looked shaky in practice.
Still, Chan claimed after the team competition that he had gotten the jitters out.
"It wasn't the best, obviously, but I've learned that I enjoy what I do," he said. "The crowd was great and I could feel the energy out there. That's why I do this. Winning and getting a medal would be great but, at the end of the day, it's not why I'm out there."
Others to watch: Denis Ten of Kazakhstan, second at the 2013 world championships but has dealt with recent injuries; Jeremy Abbott of the United States, who had a bad performance during the team competition.
If you only watch the Olympics once every four years, we have great news. Now improved, with even more luge!
This is the first time they'll have a team relay, one of the few mixed-sex events at the Games.
It goes like this: Man slides down track, goes through finish line and hits touch pad. Woman sees light and races down track. After she finishes, the two-person team makes its run and completes the race.
Officials say this will give a chance for nations that aren't dominant in any of the other luge disciplines. Or in Germany's case a chase to earn more medals for the trophy case.
They have won all three events so far at Sochi, so they're the 1 to 20 odds-on favorite.
Who else to watch: Canada and the United States also slid well during the World Cup season. If Canada goes top 3, it will be that country's first luge medal.
Women's speed skating (the long and short of it)
The red, white and blue has been red-faced so far at the Adler Arena. Team USA has zero medals so far in speed skating, but Thursday brings the women a chance to get back on the medal stand.
Now this may sound familiar, but a U.S. skater is a firm favorite to win the long-track 1,000 meters. The skater dominated the 1,000 races this season. The skater didn't do well during the 500.
But can Heather Richardson avoid the same dismal fate as Shani Davis did in the men's race?
Richardson is confident despite her eighth-place finish in the shorter race.
"I used it as a good warmup. My speed is there. I am more calm than I was in Vancouver because I know what to expect," she said, referring to the 2010 Games when she finished ninth in the 1,000.
And Richardson has another thing going for her. Her boyfriend is Dutch skater Jorrit Bergsma, so maybe some of the Netherlands' medal mojo will come the way of Team USA.
Also check out the women's 500 meters on the short track, which is sure to include a few spills. There are four quarterfinals, two semis and the final -- 44 seconds of madness each time.
Who else to watch in the 1,000: Brittany Bowe of the United States, who set the world record this season, and Olga Fatkulina, the champion at last year's worlds held in Sochi. The Russian also won silver in the 500 on Tuesday.
