The Chiang Mai Marathon is one of the activities brought about by the thought and action of a small group of Chiang Mai people, who are alumni of Mercy School. We have a passion for running a marathon and have the experience and knowledge to run a marathon for more than 30 years and have a good relationship with the marathon. Attracting over a thousand international runners, this race aims to present the Chiang Mai culture to people from all over the world and contribute to charitable causes.
