The Course: Old City to Mountain Monument
The race starts at Tha Phae Gate — the eastern entrance to Chiang Mai's old city and the most photographed landmark in northern Thailand — and finishes at the King Naresuan the Great Monument in Mae Rim district, roughly 15km north of the city. [1] That point-to-point format gives the course a genuine sense of progression: you leave the old-city moat behind, pass through Chiang Mai's northern suburbs, and climb gently toward the Mae Rim valley with Doi Suthep mountain as your western backdrop.
The Organiser: Jog & Joy, Presented by Muang Thai
Jog & Joy Co., Ltd. is one of Thailand's most established race production companies, with a portfolio of northern Thai events and a reputation for professional timing, well-stocked aid stations, and smooth race-day logistics. [1] The Muang Thai insurance brand's presenting sponsorship adds commercial backing — expect quality medals, race tees, and a well-resourced finish festival. The entry fee starts at THB 1,500, which is competitive for a full marathon with this level of production.
The Distances: Four Options, Full Marathon as Headliner
Four distances are offered: a full marathon (42.195km), half marathon (21.1km), 10km, and 3km. [1] The 3km fun run opens the event to families and first-timers, while the full marathon's point-to-point course is the main event for serious runners. December in Chiang Mai is genuinely cool — morning temperatures in the low-to-mid teens Celsius, often with a light fog over the old city at flag-off. It's as good as marathon weather gets in Southeast Asia.
