Seongnam Run Festival

About the Event

The 2026 Seongnam Run Festival has officially transitioned to a summer calendar, with the new race date confirmed for Saturday, June 13, 2026. This adjustment was mandated by the Public Official Election Act to ensure the event remains independent of election-related logistics and restrictions occurring earlier in the spring. By moving the festival to June 13, organizers are providing a unique opportunity for the running community to experience the Tancheon stream route during the peak of its early summer vitality. The race remains centered at the Seongnam Tancheon Sports Complex, serving as a high-energy hub where thousands of participants will gather to celebrate endurance and local pride under the June sun.

As the festival shifts to June 13, the atmosphere of the event evolves into a vibrant summer celebration. The route follows the cooling waters of the Tancheon, where the dense greenery provides a lush canopy for those tackling the half marathon, 10km, and 5km courses. This date change is integrated into all aspects of the festival, from the updated timing of the starting gun at 09:00 AM to the post-race ceremonies held in the complex. Participants can look forward to a resilient community spirit that thrives despite the scheduling shift, with every runner receiving their specialized souvenir kit and a commemorative medal to mark their achievement on this specific June Saturday in Seongnam.
