PYEONGCHANG, South Korea — On a snowboard and skis, Ester Ledecka is a history-making Olympic gold medalist. One of the surprising breakout stars of the Winter Games, the Czech pulled double-duty on the slopes in Pyeongchang and became the first to win snowboarding’s parallel giant slalom and skiing’s Alpine super-G. She outraced Selina Joerg of Germany to the line in the final of the snowboarding event Saturday and won by .46 seconds.
