Second double and even further
Lee-Kyung repeated her exploit at the Olympic Winter Games in Nagano in 1998 where she defended her two gold medals. She also added one more medal when she came in third at the 500m event. Her 1,000m win was particularly thrilling as she edged ahead of China's Yang Yang in the final stride.
