Meanwhile one of the friends of Yoo in an Instagram post revealed what happened in the race. “Near the finish line of the Seoul Race, I saw a crowd gathering and thought someone must have been hurt. As soon as I crossed the finish line, I looked for you on the awards podium, but then came the unsettling news, and I began to sense a reality I didn’t want to believe,” wrote Yoo’s friend and content creator Bummy.
Who was Yoo Ji-won?
Ji-won was well-known for sharing her running journeys and achievements on her Instagram account, where she had over 8,000 followers. Her final update on the platform occurred just a week prior to her passing, where she posted her time for a recent 10-kilometer run. This update received numerous tributes from friends and fans alike, highlighting the impact she had on her community and the love that surrounded her.
Meanwhile, her followers took to social media to mourn Yoo’s demise. “Every time I saw her running in a video, I thought she was an amazing runner,” wrote one admirer. Another commented, “May her soul rest in peace,” while a third remarked, “I always cheered for you, but today I have to wish you rest in peace.”
As per the report in the People, Ji-won was also an artificial intelligence semiconductor researcher at the Korea Advanced Institute of Science and Technology.
This unfortunate incident has triggered discussions regarding health and safety measures at athletic events, particularly those involving high-performance activities such as marathons. For instance, a huge row erupted after an Australian athlete Joanna Wietrzyk allowed to carry on at the Hyrox Beijing fitness competition on September 12, 2026, despite experiencing acute fecal incontinence due to food poisoning. She later apologized and retroactively withdrew from the event.
