She was a dominant force in International Short Track Speed Skating during the mid-1990s.

Chun took part in the 1992 Winter Olympics in Albertville, France, at the age of 15, but failed to win much attention.

In 1994, however, Chun won two gold medals at the Lillehammer Winter Olympic Games.

She became the first quadruple Olympic Champion in Short Track Speed Skating and the first one from Korea.

This provided the final chapter to the intense rivalry of the 2 all-time greats, as Chun would retire immediately after the meet.
