About
Mantra 116 is a formidable ultra-trail test across East Java’s Arjuno-Welirang mountain range, with the 116K route covering huge elevation gain on one of Indonesia’s toughest mountain courses. The course moves through lush tea plantations, deep mossy forest, and rugged volcanic terrain, climbing above 3,000 meters into a wild, exposed high-altitude environment. The challenge is defined by its severity as much as its scenery. Runners face technical trails, relentless descents, freezing temperatures, strong winds, darkness, and the physical strain of remote mountain terrain. More than a scenic adventure, this is a serious examination of endurance, mountain skill, and mental resilience.
