Take on one of the world's greatest team endurance challenges for a powerful cause at Oxfam Trailwalker Korea on May 16-17, 2026. This is not a traditional race but a profound humanitarian mission, where teams of four must complete a grueling 100km trek through the stunning mountain trails of Gangwon Province's Inje County within a strict 38-hour time limit. Every step taken and every won raised by participants directly funds Oxfam's vital global work, providing clean water, sanitation, and livelihood support to refugees and communities living in extreme poverty. The event pushes teams to their absolute physical and mental limits, forging unbreakable bonds of camaraderie as they navigate the course day and night, supported by dedicated volunteers. With additional 50km and 25km distance options, the challenge is accessible to a wider range of participants, all united by the common goal of creating a fairer world free from poverty. More than an athletic achievement, completing the Trailwalker is a life-changing act of solidarity, where your personal struggle on the trail translates into tangible hope for people facing unimaginable hardship. It's the ultimate opportunity to test your resilience, work as a true team, and make every kilometer count for global change.
