1. The Facts: What Is the 2026 Seoul Marathon?
The 2026 Seoul Marathon (official name: 96th Dong-A Marathon) starts at 7:30 AM on Sunday, March 15, departing from Gwanghwamun Square against the backdrop of Gyeongbokgung Palace and crossing the finish line at Jamsil Sports Complex, the iconic venue of the 1988 Seoul Olympics. Total distance: 42.195 km.
The Platinum Label awarded by World Athletics (WA) places this event in the same tier as the World Marathon Majors — Boston, New York, Tokyo, London, Berlin, and Chicago. It is the only race in Korea to hold this designation.
The course features minimal elevation change, making it ideal for fast times, and draws large fields of elite athletes and sub-elite runners alike.
2. Why Is the Seoul Marathon Trending Right Now?
- D-9 Countdown: With just nine days to go until March 15, participants' final preparations and spectator plans are spreading rapidly on social media.
- A Spring Festival Amid Crisis: Against the backdrop of a KRW/USD rate topping ₩1,500, high inflation, and Middle East tensions, running — as an unthreatening lifestyle activity — aligns perfectly with the 'healing' and 'low-harm consumption' trends.
- International Runner Influx: As a WA Platinum Label event, demand from Japanese, Chinese, American, and European runners visiting Seoul is high, making this a significant draw for the tourism sector.
- Daum Real-Time Trends Revival Effect: Since Daum's real-time search trends returned on March 3 after a six-year hiatus, keywords like 'Seoul Marathon' and 'Gwanghwamun road closures' have been trending.
3. Context & Background: 96 Years of History
The Dong-A Marathon, which began in 1931, marks its 96th edition this year. It is a historic event that continued even through the Korean War, and since the 2000s has been elevated to an international marathon — a stage where world-class athletes set Korean course records.
As the world's second-oldest marathon (after Boston, which began in 1897), its historical significance is immense. It is the only race that lets you experience the full dynamism of Seoul across 42 km.
