Reviving old tribal paths to create the wildest Ultra Trail in Asia


Nature, Tribes and Sport

Thailand Mountain Trail is born following the ‘Chiang Mai – Chiang Rai’ trail running project held in 2013. The organization has been founded to investigate and mark mountain trails in Northern Thailand. It aims is to revive the old paths previously used by hill tribes that are now disappearing. Working in relationship with local tribes, respecting nature and areas, promoting sport and outdoor activities are TMT’s main objectives. The next two years will be dedicated to create several long GR footpaths and organizing trekking, trail running and MTB trips.


Benefiting from its extensive knowledge of northern mountains and its contacts with local people, Thailand Mountain Trail will be Ultra Thai Chiang Mai’s exclusive organizer. Composed of several sportspeople passionate and locally involved TMT has revealed to be the only organization able to conduct such a project.

TMT will place its expertise at the service of the race to make UTCM an event with the highest international standards. The work is huge: marking and cleaning 150kms of paths, organizing remote refreshments points and night stages within hill tribe villages, getting all kinds of authorizations and support from the national parks, managing security and logistics.
