Upon entering college with her friend Aoi Niigaki, Ami Kurata takes an interest in cycling after seeing someone ride a folding bicycle. After visiting a few cycle shops and spotting several expensive bicycles, Ami eventually manages to find one within her price range, buying it straight away.
Over the weekend, Hinako and Yayoi invite Ami and Aoi to Miura for a ride along the coastline.
The girls set off for Yabitsu Pass, which is more challenging than the hills Ami has previously faced.
Taking an interest in owning a road bike, Ami spots one on sale and puts down a deposit for it, only to discover that the pedals and other accessories are sold separately.
Ami finally picks up her road bike, instantly coming to enjoy the feel of riding it.
Wanting to prove that she has gotten better at cycling, Ami requests to once again try riding Yabitsu Pass with the others.
As Ami gives her bikes a wash, Aoi suggests that she get her road bike checked in for maintenance.
To prepare Ami for the Azumi Autumn Ride, the girls take her on a 100km course to gain experience.
The moment the event begins, Ami ends up seperated from the rest of her team after the staff enforces a gap between them.
The girls begin their rush back down the course, using a slipstream technique to allow everyone to move at higher speeds.
Yayoi proposes that everyone go on a stargazing night ride to help Ami prepare for taking on a fléche, hiding the fact that she'd be riding all night for 100km.
