Great Britain's Lizzy Yarnold won gold at the Skeleton World Championships in Winterberg to complete the career 'grand slam' of major titles.
The 26-year-old added the world crown to her Olympic, World Cup and European golds after another record-breaking performance on Saturday.
Having smashed the track record on Friday, Yarnold lowered it again in the final of her four runs to clinch the victory in a combined time of three minutes, 49.95 seconds.
Second place went to Germany's Jacqueline Lolling, 0.67secs further back, with Canada's Elisabeth Vathje third (+0.79secs).
A delighted Yarnold told BBC Sport: "World champion as well as Olympic champion and European champion, it's all I ever wanted."
Yarnold claimed the European title in Austria last month to add to her Olympic success in Sochi last year and her World Cup triumph during the 2013/14 season. She took silver at this season's World Cup.
Her compatriot Laura Deas was seventh in the World Championships on Saturday, with fellow Briton Rose McGrandle ninth.
