Merapi Merbabu De Trail

About the Event

Test your limits at the Merapi Merbabu de Trail, an epic race that delivers Indonesia's hardest high-altitude effort under 20K. This isn't about distance; it's about conquering 2,940 meters of elevation gain on a classic route to the summit of Mt. Merbabu at 3,142m. With a 14-hour cutoff and a 1:00 AM flag-off, this is a true mountaineering challenge disguised as a trail run. Choose your category from the grueling 20K to the accessible 5K, all set against the stunning backdrop of Mt. Merapi. Secure your early bird entry for a relentless journey where you'll truly have your #HeadInTheClouds.
