Great Britain’s Lizzy Yarnold faces a battle to win a second successive Winter Olympics gold at the halfway stage of the women’s skeleton in Pyeongchang.
Yarnold is in third place in the overnight standings, trailing leader Jacqueline Loelling of Germany by 0.10 seconds after two runs.
British team-mate Laura Deas is just 0.07secs behind in fourth as Team GB look to add to Dom Parsons’ bronze medal in the men’s event won earlier in the day.
Yarnold, who won gold in this event at Sochi in 2014, set a track record of 51.66 seconds in her opening heat.
The 29-year-old told BBC Sport: “I have got a throat or sinus infection going on. I am struggling to breathe enough as it cold and dusty.
“I am well in the mix and that is the goal. The goal is to be the first Briton to retain a title and it will not be easy, but I hope to do it for all the people who have supported me.”
The third run starts at 11.20am on Saturday with the final run at 12.45pm.
