Otome no Chikyuu no Hashirikata

Ayumi Miyamura came to Mt. Mitake in Okutama, Tokyo to lose weight. On her way to the trailhead, she encounters a strange runner who dashed past her and entered the mountain from a back road. Unbeknownst to him, this was his first encounter with a map and compass, and the start of his quest to participate in an "adventure race." This is the start of a next-generation outdoor manga about enjoying nature with all one's being.
