Bangkok / Monaco / Paudex, 23 December 2020 - The first edition of the World Mountain and Trail Running Championships (WMTRC) will be held 11-14 November 2021, in Chiang Mai, Thailand. Over the four days, the action-packed championships program will include vertical uphill mountain races, short and long trail races for senior athletes and the classic mountain races for both seniors and juniors. Situated 700km north of Bangkok, on the banks of the Ping River, Chiang Mai is the largest tourist spot in the northern part of Thailand thanks to its unforgettable scenery. The mountainous surroundings and the city’s growing reputation for outdoors mass sporting events make it the perfect place to host the first-ever combined World Championships. This new biennial event further develops the partnership between the World Mountain Running Association (WMRA), the International Association of Ultrarunners (IAU) and the International Trail Running Association (ITRA), with support from World Athletics.
