神戸・六甲 トレイルラン（有馬温泉）11km 2026

Arima Onsen is central to this Rokko trail-running event, structured as "Arima sightseeing" with time on the mountain rather than a competitive race. The course is designed as a group outing on Rokko, featuring a stop for a commemorative photo at Mount Rokko’s highest point. It offers a guided trail day feel for road runners transitioning from pavement, novices to trail running, and older participants seeking dedicated mountain time. The draw is the shared mountain pace: the "unease of going into the mountains alone" is mitigated by the group format, intended to make the trail feel more secure and pleasant. Anticipate a course-oriented day with ascents, regrouping, and natural pauses suitable for a trail tour. The notable feature concludes after the run: participants can optionally bathe in Arima Onsen, recognized as one of Japan’s three renowned hot springs.
