About the Event

Embark on the ultimate test of human endurance at 500 Thailand, the nation's longest and most legendary ultramarathon, unfolding from January 11 to 18, 2026, in the mountainous terrain of Pai, Mae Hong Son. This is not merely a race; it is an epic 500-kilometer journey that pushes participants beyond physical limits into a profound mental and spiritual expedition. Traversing remote trails and high-altitude passes, runners will confront relentless distance, sleep deprivation, and their deepest reserves of fortitude, guided by the event's core philosophy: "Conquer the Distance." It stands as the definitive apex of Thai endurance sports, where the landscape itself becomes both adversary and ally.

This eight-day pilgrimage from January 11th is a transformative experience reserved for the world's most resilient adventurers, offering minimal support against a backdrop of stunning natural beauty. More than a competition, it's a collective saga of perseverance where every step forward is a victory over doubt, making the finish line one of life's most hard-earned achievements. To complete 500 Thailand is to join an exclusive pantheon of athletes who have mastered the art of enduring the unendurable.
