Ascend into trail running legend at the 2026 Namhansanseong Trail Run, a premier mountain challenge scheduled for Saturday, June 6, 2026. This event has earned a formidable reputation for its relentless verticality, centered around the infamous 1,222-step climb that tests the grit of even the most seasoned mountain runners. Set within a UNESCO World Heritage site, the course traverses the ancient stone ramparts and rugged ridges of the Namhansanseong Fortress, offering a unique intersection of South Korean history and grueling athletic endurance.
With a prompt 9:00 AM start, the race plunges participants into a landscape of technical single-tracks and steep stone staircases that demand constant focus and agility. As you navigate the high-altitude paths of the Gyeonggi province, the physical struggle is balanced by panoramic views of the Seoul skyline and the surrounding emerald valleys. Organized by the Korea Mountain Marathon Federation, the event adheres to elite trail standards, providing strategically placed aid stations and expert course marking to ensure a safe yet uncompromising adventure in the wild.
The 2026 edition stands apart from standard mountain runs by offering a profound sense of accomplishment at every summit. Whether you are an elite vertical kilometer specialist or a trail enthusiast seeking a "bucket list" achievement, the supportive community atmosphere and the historic grandeur of the fortress walls make for an unforgettable race day. Every finisher earns their place among the mountain's legends, proving their strength against one of the most iconic stair-climbing challenges in Asia. Secure your entry to experience the power, the pain, and the prestige of the Namhansanseong Trail.

Learn more about the host city, Seoul.
Seoul (서울) is the capital of South Korea. With a population of over 9 million, Seoul is by far South Korea's largest city and one of East Asia's financial and cultural centers. A fascinating blend of ancient traditions and cutting-edge digital technology, home to endless street food vendors and vast nightlife districts, an extraordinarily high-pressure educational system and serene Buddhist temples, a dynamic trend-setting youth culture and often crushing conformism, extraordinary architecture and endless monotonous rows of grey apartment buildings, Seoul is a city filled with stark contrasts, contradictions, and paradoxes. People in Seoul can enjoy various artistic activities such as plays, musicals, and concerts.
