With this win, at age 14, Kim became the youngest gold medalist until she lost this record to Kelly Sildaru who won gold in 2016 at the age of 13. In the 2016 X Games, she became the first person under the age of 16 to win three gold medals (and thus the first such person to win back-to-back gold medals) at an X Games. At that year's U.S. Snowboarding Grand Prix, she became the first woman to land back-to-back 1080 spins in a snowboarding competition. She scored a perfect 100 points, and is believed to be the second rider ever to do so, after Shaun White.
