THEP SADET TRAIL 2026

The Thep Sadet Trail Race returns to Chiang Mai on October 30, 2026, inviting runners to explore the breathtaking beauty of winter. This year’s edition features four distances: 15K, 30K, 50K, and a new challenge—the 100K route.
The 100K distance is designed for seasoned trail enthusiasts willing to tackle ridge crossings, deep forest trails, and significant elevation changes. The 50K journey offers scenic viewpoints and charming local villages along the way, while the 30K "Winter Classic" showcases the morning mist and winter forest beauty that runners adore.
For newcomers, the 15K "Blooming Starter" is an ideal introduction to the magic of Thep Sadet. Each distance promises a unique blend of natural splendor, from crystal-clear streams to ridgeline paths overlooking sea-like mists, making this race not just about competition but also about personal discovery.
The event takes place in Doi Saket District and includes awards for age-group trophies across all distances, celebrating the achievements of runners aged 20-39, 40-49, 50-59, and over 60. Race pack collection will be available at Decathlon Chiang Mai on October 29th from 10:00 AM to 6:00 PM.
Join the race for an unforgettable adventure through Thailand's winter landscape. Braving the trails of Thep Sadet is a journey that captures both the heart and soul, leaving every participant with memories to cherish long after crossing the finish line.
