About CM6

CM6 is a trail running event in Chiang Mai, Thailand – aimed to be an event for runners with some degrees of expertise in ultra-distance trail running.

At CM6, climbs are long, steep in places and with a lot of elevation gain but not with a lot of technical difficulties – all within easy reach of Chiang Mai City.

We feel that CM6 offers the right degree of challenge for runners who ultimately will be seeking greater challenges elsewhere. 

Shorter distances are also available, namely the CM5, CM4, CM3 , CM2 and CM1.
