Set in the historic city of Chiang Mai in northern Thailand, the Marathon 2026 edition invites runners across multiple distances from 5 km to the full 42.195 km marathon. With the finish located at Chiang Mai University, participants traverse city streets and local scenery before crossing the line in the heart of town. While the flatter routes offer potential for strong times, the local climate, early start and post-race celebrations reflect Thai hospitality and culture. Whether you’re aiming for a milestone finish, exploring new running terrain or simply enjoying a well-organised event, this race delivers a memorable experience in a vibrant regional setting.
