1pt/6mThe perfect ultra introduction—respectable distance meets mountain challenge
CM3 strikes the ideal balance for runners stepping up from shorter trail races or transitioning from road marathons. After the signature 10km climb to the Hmong village HQ, the route ventures through Doi Pui Summit territory and remote Pa Nok Kok Village. Technical descents test both skills and stamina, while the overall distance provides a true ultra experience without overwhelming newcomers to the format.
