1. The Facts — What Is This Race?

2026 Run Your Way HALF RACE SEOUL is a Seoul urban half marathon sponsored by New Balance. The official distance is 21.0975km (full half marathon course). Registration was conducted via raffle (lottery) rather than first-come-first-served, and confirmed participants start at the northern end of Gwanghwamun Square, running through Seoul's most iconic streets before finishing at Jamsil Olympic Stadium.

The event was originally announced for Sunday, March 1st — Independence Movement Day — but was rescheduled to Monday, March 2nd after major national events converged on the same date: the 107th March 1st Movement Commemoration Ceremony, the One Korea Citizens' Alliance rally at Gwanghwamun, and the Ten Million People Movement rally at Seoul Station.

The race organizers stated: "We had no choice but to adjust the schedule to avoid conflict with national events and large-scale rallies, in order to ensure participant safety and smooth race operations."

2. Why It's Trending Now

① The 'Running Craze' of the March 1st Holiday

The 2026 March 1st holiday period (3/1–3/2) became a two-day break thanks to the March 2nd substitute holiday designation. A large number of MZ generation runners eager for an 'active holiday' signed up, and the hashtags #HalfRaceSeoul and #GwanghwamunRun have been spreading rapidly across social media (Instagram, YouTube, TikTok).

② Gwanghwamun to Jamsil — A Seoul Landmark Crossing Course

Departing from the area around Gyeongbokgung Palace and Gwanghwamun, passing Cheonggyecheon, Jongno, and Euljiro, crossing the Han River, and arriving at Jamsil Olympic Stadium — this course captures both the historical and modern landscapes of Seoul in a single route, making it a popular running route among international runners for its photogenic landmarks.

③ Running Culture Goes Mainstream

The rapid spread of 'running crew' culture among MZ generation between 2024 and 2025 significantly increased the number of domestic race participants overall. New Balance is positioning this race as a 'running culture festival' through collaborative marketing with major running crews.

3. Context & Background — Seoul's Major Marathon Ecosystem

Seoul sees a concentration of major marathon events between March and April.

Major marathons also generate significant tourism economic benefits. International participants staying 2–3 days in Seoul before and after the event — spending on accommodation, food and beverage, and shopping — has established itself as a form of 'sports tourism.'

5. Outlook — What This Race Leaves Behind

1. New Balance's Brand Rise: In a domestic running market previously dominated by Nike and Adidas, New Balance is rapidly building brand awareness as the sole title sponsor of 'Half Race Seoul.'
2. Seoul's Sports Tourism Strategy: Seoul is developing sports events into major annual tourism content for 2026, and this race is part of that initiative.
3. Institutionalization of Running Crew Culture: The trend of informal running club culture being absorbed and formalized into official large-scale races continues.
4. Spring Sports Consumption Trigger: The pattern of surging purchases of running shoes, apparel, and supplements around the race period repeats. New Balance's free entry ticket promotion tied to purchases of the 1080 v15 is a prime example.
5. Demand for Active Holiday Closings: Scheduling a major running event on the Monday — the final day of a two-day holiday — targets the trend of 'finishing the break actively without the holiday burnout feeling.'
