About the Event

Test your trail running and navigation skills at the 6th Cheonggyesan Trail Running, a purist's event scheduled for July 19, 2026. Unlike conventional races, this 13km/10km challenge requires runners to rely on pre-downloaded GPS routes rather than course markings, creating a more immersive and self-reliant mountain experience. The 8:00 AM start from Yangjae Freight Terminal kicks off a journey through Cheonggyesan's beautiful trails, with smartphone and power banks mandatory for safety. This race is perfect for marathoners looking to transition to trail running and experienced trail runners seeking a more authentic, technology-assisted wilderness adventure.
