Trail of The Kings - Lake Toba by UTMB

Trail of The Kings is a trail running event held on Samosir Island in Lake Toba, scheduled from 12 to 14 June 2026. The event is set within the caldera area of Lake Toba, described by the organiser as the site of the largest volcanic eruption. The name references the Bataknese people and their historical role in creating routes through the region.

Routes traverse varied terrain including rugged trails, dense forest, hills and heritage sites. The longest route is a 100 kilometer course that passes through sections of the caldera and surrounding valleys. The programme groups several race categories across two days, with distances that range from short community runs to ultra distance.

Race distances include:

• Caldera Crown 100K
• Ultimate Expedition 60K
• King's Ascent 28K
• Legacy Dash 10K
• Legend Leap 5K
• Kids race

The organiser notes that registrations for the event are closed. The description of the event emphasises landscape and cultural context rather than competitive details.
