Malaysia's premier UTMB and Western States qualifier through cool mossy highland jungle
MOSSY100 is a 102.6km loop through the high-altitude jungle of Cameron Highlands, climbing nearly 5,000m through cloud forest, tea plantation ridges, and mossy singletrack. Starting at 2am, runners navigate technical terrain in darkness before dawn breaks over the highland plateau. Cool temperatures (15–22°C at race elevation) and persistent mist make this one of Southeast Asia's most atmospheric 100K races. As one of only three races in Malaysia to qualify for both the UTMB Index and the Western States Endurance Run, CULTRA attracts a competitive international field from 40+ countries.
