Chiang Khan Ultra

Discover a unique blend of physical challenge and profound cultural immersion at the Chiang Khan Ultra 100, an extraordinary endurance journey along the legendary Mekong River in Loei province, Thailand. The event is expected to return in mid-February 2026, offering two breathtaking routes: a scenic 65km course or a demanding 100km adventure, both tracing peaceful riverside roads and weaving through vibrant local villages with stunning, continuous river views. More than just an ultra, this is a moving cultural festival where the journey is fueled by the incredible enthusiasm of local communities, who offer roadside support, cheers, and traditional performances that turn every kilometer into a celebration. With generous cut-off times designed for enjoyment over sheer speed, it's a perfect invitation for seasoned ultrarunners seeking a soulful adventure and newcomers ready to step up to the distance in one of Southeast Asia's most stunning and welcoming landscapes. Prepare for an unforgettable experience where every stride is a connection to the mighty Mekong and the warm heart of Isan.
