The 50-mile sweet spot for serious mountain running

CM4 represents the global 50-mile standard adapted to Chiang Mai's challenging terrain. The race features a massive circular loop through remote Hmong communities, steep climbs to Doi Pui Summit, and technical waterfall descents often tackled in darkness. This distance attracts runners seeking substantial challenge while maintaining manageable time commitments. Expect rocky, twisty, rooty trails that demand quality lighting equipment and technical trail skills.
