21-fold. That is how much the number of Seoul marathons sponsored by the central government grew in one year. Citing Seoul City's tally, Gyotong Ilbo and News1 reports, central government-sponsored races went from 1 in 2025 to 21 in 2026. In the same period, Seoul City-sponsored races fell from 15 to 7. The weight of marathon sponsorship has shifted from Seoul City to the central government.
Seoul marathon sponsorship 15→7, central government 1→21
| Sponsor | 2025 (count) | 2026 (count) | Change |
|---|---|---|---|
| Seoul City | 15 | 7 | -8 (-53.3%) |
| Central government | 1 | 21 | +20 (21x) |
Seoul City's sponsored races fell by 8, a 53.3% decline. This is the 8 cut as a share of the 15 in 2025. Central government sponsorship rose by 20. However, the two figures should not be added together to read as a total race count. It has not been confirmed whether any single race was co-sponsored by both Seoul City and the central government, and neither a race-by-race list nor the original aggregate data has been obtained.
The concentration is even clearer when looking only at races that actually closed roads. From January to September 2026, there were 19 marathons in Seoul with wide-area traffic control, and 15 of them were sponsored by central government ministries. Dividing 15 by 19 gives 78.9%. These 15 races and the 21 annual sponsored races cannot be directly compared because the counting periods and scopes differ.
Name sponsorship and traffic control: separate authority
The number of sponsored races does not indicate the scale of support. News1 explained that name sponsorship does not mean permission to hold a race or budget support. In other words, the agency lending its name and the agency managing citizen inconvenience are separate. Both outlets pointed out this shared structure, in which management authority is scattered across several agencies.
Seoul City has tried to fill this gap with cooperation documents. News1 reported that in 2026 the city sent central ministries and police requests to refrain from name sponsorship and to strengthen traffic management, among other things, a total of 8 documents, according to the report. Data Seoul City submitted to the National Assembly, cited in the same report, shows that of 2,719 marathon-related complaints from 2022 through July 2026, 2,266 (83.3%) were related to traffic control.
Marathon start before 7:30 a.m. / 65 dB noise standard
Operating standards already exist. In January 2026, Seoul City prepared marathon event guidelines. Seoul City official press release shows the start time would be moved up to before 7:30 a.m., and noise would be managed at 65 dB or below. It was not confirmed in the reporting how these guidelines apply to races sponsored by central government ministries.
The next step Seoul City announced is consultation with relevant agencies. Through that consultation, it plans to adjust race schedules, courses, and traffic impacts. It said growing running demand would be absorbed through lifelong sports programs. As of October 21, 2026, the consultation schedule, the list of target races, and the sponsorship amount for each race had not been confirmed.
