Official event pageWhat this race demands
This 163 km trail running race in the Shinetsu Highlands demands exceptional distance management and sustained pacing over a multi-terrain course. Athletes must prepare for a prolonged effort that will extend well past a standard day of continuous movement.
Ultra-Distance Endurance
Covering 163 km requires advanced physiological and structural durability to handle repetitive impact and continuous forward progression over many hours.
Terrain Adaptability
Traversing the mountain areas and regions of the Shinetsu Highlands demands technical footwork and stability across varied off-road surfaces.
Given the duration required to complete 163 km of trail running, athletes should consume 60 to 90 grams of carbohydrates per hour to maintain energy balance throughout the event.
