Lizzy Yarnold overcame dizzy spells to win a second successive women’s skeleton gold medal and become the first Briton to defend a Winter Olympics title.
The 29-year-old Sochi 2014 champion trailed leader Janine Flock of Austria entering the fourth and final run, where she overhauled the deficit to win by 0.45 seconds.
British teammate Laura Deas claimed bronze by 0.02secs as Britain won two medals in the same event for the first time in Winter Olympics history.
Yarnold trailed by 0.10 overnight after complaining of being dizzy, but cut the deficit as overnight leader Jacqueline Loelling of Germany slipped back to third place after the third run.
The Briton trailed Flock by 0.02 ahead of the fourth and final run, meaning Yarnold was the penultimate slider to take to the track and had to watch her rival’s run.
Yarnold clocked a track record of 51.46 to lead by a commanding fashion and Flock floundered, relinquishing her spot on the podium to spark jubilant celebrations among a sizeable British contingent at the Olympic Sliding Centre.
Britain have now equalled their record Winter Games medal tally of four – and there are plenty of further opportunities to come.
You can watch Yarnold's immediate reaction to winning gold once again in the video below.
It is the first time ever Britain have won three Winter Olympic medals in the same day, overtaking the record two from Chamonix in 1924.
And, Yarnold is now Britain’s most decorated Winter Olympian.
Only figure skaters Jeannette Altwegg and pair Jayne Torvill and Christopher Dean, who have one gold medal and one bronze each, also have multiple medals for Britain.
And now Yarnold is in an exclusive club all of her own.
