This is not a leisure trail run.
Merbabu Trail Run is a confrontation with the mountain.
Rising above Central Java, Mount Merbabu exposes runners to vast savanna ridgelines, volcanic soil, relentless climbs, and open terrain where wind, cold, and altitude strip away excuses.
The course demands absolute discipline — long ascents with no shelter, technical volcanic trails, and elevation that tests both lungs and legs. Weather can shift without warning. The mountain sets the rules.
Only runners with preparation, restraint, and mental control will endure the full distance and reach the finish.
