What Makes It Great

The nocturnal edition of the popular 56-kilometer Hmong trail through Doi Suthep-Pui National Park. An 18:00 start from Chiang Mai PAO Park transforms the same hill tribe and forest loop into a headlamp adventure through the night, earning 4 UTMB Running Stones on the same 2,400-meter course.
