Nan Mountain Trail

Nan Mountain Trail carves its way through the steep, wild terrain of Khun Sathan National Park — a raw, uncompromising mountain-running experience across every distance. The course blends savage climbs, exposed ridgelines, and sweeping cloud-sea panoramas, creating a route that is both brutally demanding and undeniably beautiful. Runners tackle iconic sections like Pha Phueng and Doi Thong, quiet but punishing ridges known for their relentless gradients and deep, layered mountain views. Every distance is purpose-built — from approachable routes for new trail runners to full alpine-style battles for seasoned mountain athletes — supported by enhanced night-running safety and thoughtful course design. This race has earned its reputation as one of the toughest trail events in Thailand, and the crown jewel is NMT100, boasting an extraordinary 6,900 meters of elevation gain — the highest of any 100 km race in the country. If you’ve finished a 100 km race before —but you’ve never run here— you haven’t met the true standard of what a “human 100” really is. Nan Mountain Trail delivers a pre-race vibe full of anticipation, and a warm, humble finish-line atmosphere that reflects Nan’s mountain spirit — rugged, serene, and unforgettable.
