The newest addition to the UTMB® Ultra Trail du Mont Blanc family, Thailand by UTMB®, will take runners on an unforgettable journey to the highest mountain in Thailand, Doi Inthanon, also known as the "roof of Thailand". As they ascend from 400 to 2100 meters above sea level, runners will be able to observe the changes in the forest, as well as local biodiversity. Along the way, they will get to experience the peaceful ways of life of the Hmong and Pga-Gan-Yaw Karenic tribes, as well as the awe-inspiring views of terrace paddy fields illuminated by golden ears of rice, and picturesque montane farms. The race will begin and end at the Doi Inthanon National Park Head Quarter in Chom Thong District, Chiang Mai, THAILAND.
