About the Event

Conquer the dramatic, high-altitude wilderness of Indonesia's second-highest volcano at the Sembalun Mountain Marathon, the pinnacle challenge of the MMF series on 27 November 2026. This formidable race offers three epic distances—a full 42km marathon, a 21km half, and a 7km introductory route—each traversing the extreme volcanic terrain of Mount Rinjani with its breathtaking views of the Segara Anak crater lake. Designed for experienced trail runners, it demands rigorous preparation and full mandatory gear to safely navigate remote Sasak villages and pristine, untamed landscapes. As the most demanding event in the festival, it promises an unparalleled mountain running adventure where every grueling ascent is rewarded with otherworldly vistas. Test your limits against one of Southeast Asia's most iconic and sacred peaks, where the raw power of nature defines the course. Secure your entry for a true expedition-style race that transcends conventional trail running.
