Overview

Held in Nakanoto, Kashima District, Ishikawa Pref., Japan, the Nakanoto Treasure Trail Run Festival packs 2300 meters of elevation gain into its 50-kilometer course. That works out to 46 meters of climbing per kilometer, demanding steady ascending legs from start to finish.

The 9.5-hour time limit requires an average pace of 11.4 minutes per kilometer to beat the finish line. That makes the cut-off tighter than 56% of 50k races and more generous than 44%, offering little room to stall on the steep ascents.

With 224 finishers in 2025, the event draws a crowd bigger than 92% of 50k fields and smaller than 8%. Entry costs 11000 yen for the race scheduled on November 1, 2026.
