The course departs from Kenmin no Mori into the forested terrain characteristic of Kaga's mountains. Mixed terrain suggests runners will encounter both maintained trail sections and more technical passages, though the exact nature of these segments has not been detailed by race organizers. Japanese trail maintenance tends toward careful preservation of natural features rather than extensive modification, so expect roots, rocks, and variable footing even on established paths.
At 20 kilometers, the route provides a contained mountain running challenge suited to runners building trail experience. Forest canopy sections will offer shade, though June humidity in coastal Ishikawa Prefecture can make the effort feel harder than the distance suggests. The course showcases regional trail character while remaining accessible to runners with moderate fitness and basic technical skills.

The 100K route explores the full scope of the Kanan Sanzan range, linking a series of peaks through dense beech forest corridors that have stood for centuries. The terrain alternates between technical singletrack and occasionally runnable ridge sections, though runners should expect the climbs to be characteristically Japanese in their directness. Forest canopy provides intermittent shade, though humidity persists regardless of sun exposure.
Aid station spacing follows Japanese ultrarunning conventions, typically more frequent than Western races, often featuring local foods alongside standard ultra fare. The course passes through small mountain settlements where community support adds a distinctly regional flavor to the experience.
