The biggest surprise medallist of day four was
Belarus biathlete Anton Smolski, who was ranked 18th in the world in the 20km
event on Gracenote's podium rankings.
He had finished 19th in both of his World
Cup events over the distance this season.
Coming up on Day Five

Women's snowboard cross brings one of Britain's biggest medal prospects in Beijing. Charlotte Bankes is the reigning world champion in a guaranteed crowd-pleaser of an event, in which athletes go toe-to-toe down a course of bumps and jumps, often with spectacular consequences.
Bankes' win in 2021 wasn't a one-off, either - she won silver in 2019 and is this season's World Cup points leader. France's Chloe Trespeuch will be a close rival in Beijing, as will Lindsey Jacobellis, still a regular podium occupant for the US after making her Olympic debut in 2006 (where she took silver after an infamous late fall while leading). Head-to-head racing begins at 06:30 GMT and the final will take place shortly after 07:45 GMT.
One of Great Britain's best hopes for an Olympic podium finish slid south today with Jen Dodds and Bruce Mouat coming a curling cropper in the mixed doubles gold-medal match against an inspired Sweden.
Mad props for Aberdeen schoolgirl Kirsty Muir though who finished fifth in the big air final that had the eyes of the world on it in the early hours of this morning GMT.
Day Four highlights
Well then, that was Day Four. The best so far? I would say so. Why?
Well....
American triple world champion Nathan Chen delivered a world record-scoring routine to lead the men's figure skating at Beijing 2022...
...18-year-old Games golden girl Eileen Gu landed a 1620 - four and a half rotations - for the first time in her competitive career to take gold for China in the big air final.
...and Czech Ester Ledecka keeps on course for a unique Winter Olympics double-double after retaining her women's snowboard parallel slalom title in Beijing.
The 26-year-old will also attempt to defend her super-G title on skis later in the Games.
Olympic dream realised - on borrowed skates
Short-track speed skating
After 45 PCR tests in 21 days, a missed event and his luggage being lost, Casey Dawson was finally able to realise his Olympic dream - on borrowed skates.
The 21-year-old speed skater tested positive for Covid-19 three weeks ago, and a mix-up over testing further delayed his arrival in Beijing.
When clearance finally came, Dawson made the 6,000-mile journey from Salt Lake City to Beijing - via Atlanta and Paris - and arrived just hours before stepping onto the ice for the 1500m.
The American finished second last, but were medals given out for overcoming the odds, he would surely be taking one home
That didn't last long. Sweden are back in front against Denmark and it's a fine effort from Lisa Johansson, drilling into the bottom corner from distance. Their first powerplay goal of the tournament.
Denmark level against Sweden
Women's Preliminary Round
Game on at the Wukesong Sports Centre!
Josefine Jakobsen's effort from distance was going off target, but Julie Oksbjerg is alert and diverts the shot goalwards to bring Denmark level against Sweden.
The Danes needs to win in regulation time in order to reach the quarter-finals.
Meanwhile, Finland are running riot against the ROC. Jenniina Nylund and Minnamari Tuominen have scored to make it 4-0.
