Despite challenging conditions, including snow and rain affecting course conditions, Kim's resilience shone. She finished the race strong, leading from the outset and overtaking legendary skier Oksana Masters during the competition. Kim had previously triumphed in a 12.5 km biathlon event, becoming the first South Korean female athlete to earn gold at a Winter Paralympics, illustrating her remarkable prowess across multiple disciplines and solidifying her place in sports history.
