Route: Thailand - Mae Sot to Mukdahan (West to East)

This route is a remarkable journey that stretches across the width of Thailand, offering a unique blend of natural beauty, cultural richness, and physical challenge. For someone unfamiliar with the area, the route provides an extraordinary opportunity to experience Thailand’s diverse landscapes—from the mountains and rivers of the western border with Myanmar to the rolling hills and open plains of the northeast, all the way to the banks of the Mekong River at the eastern frontier near Laos.

What makes this route truly special is its contrast. You begin amidst the remote, hilly terrain at the Thai-Myanmar Friendship Bridge, surrounded by nature’s raw beauty. As you move through Thailand, the landscape constantly evolves—passing through rural villages, farmland, ancient temples, and vibrant towns like Phitsanulok and Khon Kaen. Each segment offers something new, whether it’s a stretch of road flanked by rice paddies or the peaceful countryside dotted with historical landmarks.

The route follows the Asian Highway 12 (AH12), which acts as a central artery through Thailand, making it easily navigable but no less challenging. The road itself is a lifeline between regions, connecting Thailand’s heartland to its borders, yet it feels remote and peaceful for much of the run.

But what truly sets this route apart is the emotional and physical journey it represents. Covering such a vast distance—over 700 kilometers from west to east—pushes both the body and the mind to their limits. The combination of challenging hills, long stretches of road, and the unrelenting heat makes it a test of endurance. Yet, for those who take on the challenge, it’s an incredibly rewarding experience. There’s a profound sense of accomplishment in knowing that you’ve traversed an entire country on foot, experiencing Thailand in a way that few others have.
