Khaoyai-Prachin Ultra 2026

The Khao Yai side of Prachinburi is just as beautiful as the Pak Chong side, I must say. We’d like to warmly invite ultra runners to come and experience our hometown—exploring the diversity of trails in this race. The course design for both distances is well-balanced, making this an ultra marathon with some of the most stunning scenery. The race starts at King Mongkut’s University of Technology North Bangkok, Prachinburi Campus, passing through Ban Naprue, Ban Noen Hom, and Ban Wang Nam Khun, with the first checkpoint and turnaround point at Wang Bon Reservoir (Km 15). Along the route, runners will experience the beauty of “Four Cliffs and Five Waterfalls”: Wang Bon Reservoir, Noen Hom Checkpoint in Khao Yai (Prachinburi side), Pha Phueng, Wang Muang Waterfall, Khlong Mai Plong Reservoir, Khao Ito, Pha Hin Son, and Phra Phutthachawaratdhi Sri Prachin Sirinthorn Lokanath—the largest Naga Buddha image in Thailand. These are the key highlights of our race course.
