第4回 Around Toki River

Around Toki River is a trail running event set in the towns of Ogose, Tokigawa, and Ogawa in Saitama Prefecture. The race area centers on the mountains and valleys around Tokigawa, a town that contains the headwaters of the Toki River and is known for forests that nurture clear streams. The surrounding landscape includes the group of local summits called the Tokigawa 10 Peaks, with ridgelines, temple areas, wooded slopes, and viewpoints that look out across the wider Kanto region. The event emphasizes running through a varied satoyama environment where natural scenery and local history sit close together. Participants pass through green mountain terrain, forest paths in an area associated with timber and woodland culture, and routes that require awareness of other trail users and nearby communities. The source material highlights the appeal of experiencing trails embraced by rich nature, with beautiful views and a course that blends the character of the river source area, regional mountains, and historic places. Because the race is held in a natural outdoor setting, the event also stresses self-management, route awareness, and respect for hikers, residents, and the environment. Runners are expected to understand risk management, make safe decisions, follow course guidance, greet and yield to others when needed, and carry out their own waste. The character of the event is therefore not only competitive trail running, but also a mountain journey through the forests and cultural landscape of western Saitama.
