South Korean running influencer and KAIST researcher Yoo Ji-won dies after collapsing during the Seoul Race half-marathon on October 11, shortly before the finish line. Reports say she collapses with about 500 metres remaining and is taken to a medical facility, where she later dies.
Outlets describe her as 25 years old and note that the official cause of death has not yet been confirmed by medical authorities. The Seoul Race organising committee confirms the incident and tells participants that emergency first aid is provided on site, followed by ambulance transport. The committee says it will examine the circumstances and carry out follow-up measures.
Across coverage, Yoo’s online presence and community recognition are emphasized, with friends and followers sharing tributes on her social media accounts after her death. While the reports agree on the timing, location on the course, and the fact that she dies after medical treatment, they differ on whether the death is described as occurring at a specific point on the route and do not cite any confirmed medical determination.
