あさひトレイル ZERO to ZERO 2026

Hisui Coast serves as the start and finish point, with the race beginning and ending at sea level. This creates a true 0m-to-0m trail day, distinct from a standard out-and-back. From the water's edge, the route ascends towards mountain castle ruins, sites where warriors battled from the Heian through Sengoku periods, imbuing the run with a sense of ancient ground underfoot. The course shifts character rapidly: sea air at the outset, a climb into historic hill country, then passage through "soft village mountain trails" before descending to the same 0m finish. That ZERO to ZERO characteristic is a key draw, but the overall appeal lies in the blend of a coastal start, exploration of castle ruins, and the yielding satoyama trails.
