Overview
Holding an extreme vertical profile in Nakato, Manno, Kagawa Pref, Manno Mountain Madness 2026 packs 5600 meters of elevation gain into an 80-kilometer route. Averaging 70 meters of climb per kilometer across 2 loops of 40 kilometers along the Asan Mountains, the trail race demands severe climbing legs balanced against runnable stretches.
The event gives runners a 17-hour limit, requiring a minimum cutoff pace of 12.8 minutes per kilometer. That standard makes its deadline more generous than 72% of 50mi peers and tighter than 28%, offering extra buffer against the heavy elevation profile.
Having debuted in 2022, the race enters its fifth edition on October 25, 2026, with an entry fee of 17000 Yen. Its 44 finishers in 2025 placed it in a mid-sized tier—bigger than 45% of 50mi fields, but smaller than 53%—where participants navigate technical terrain without overcrowding.
