[a] A mixed team relay event was contested for the first time at the 2014 Winter Olympics in Sochi.
In the women's event, Germany's Silke Kraushaar leads the medal count with three, one of each color.
Ortrun Enderlein, representing the United Team of Germany, was the first woman to win the singles event in 1964.
East Germany's Hans Rinn and Norbert Hahn, and Austrian brothers Andreas and Wolfgang Linger, are the other pairs to have won two times, both of them in consecutive Olympics.
In 1972, two gold medals were awarded to an East German (Horst Hörnlein and Reinhard Bredow) and an Italian pair (Paul Hildgartner and Walter Plaikner), who finished with exactly the same time.
