About This Race
The 100K represents the ultimate test at Trail of the Kings, taking runners on the most comprehensive journey across Samosir Island's volcanic terrain with extended time among the dense forests and heritage sites that shorter distances only glimpse. This distance demands experienced ultrarunners who can manage pacing and nutrition across the full spectrum of technical terrain, from steep volcanic climbs to root-laden forest sections, while maintaining focus through the mental challenges of a long day on the island. Runners choosing this distance should be prepared for significant elevation gain and the unique experience of witnessing the landscape transform through different lighting conditions as they trace the ancient pathways of the Bataknese kings.
