Ami's friend from college, Miya Saeki, hears about her interest in cycling. To prepare Ami for the Azumi Autumn Ride, the girls take her on a 100km course to gain experience. Enjoying both the rides and the food at the rest stops, Ami manages to make it past 100km without even realising it. The girls soon arrive at the Azumi Autumn Ride event, checking into an inn and enjoying the communal baths. After a rested evening, the girls get ready to set off as the event begins.
