The girls set off for Yabitsu Pass, which is more challenging than the hills Ami has previously faced. Halfway through the route, however, Ami gets a painful cramp in her legs as a result of sweating so much, prompting the others to call it a day despite Ami's protests. Despite the disappointment of her failure, Ami remains determined to keep cycling so she can eventually keep up with everyone. Wanting to cheer Ami up, Aoi invites her on a family trip to Shibu Pass, where they meet another cyclist who tells Ami the advantages of using a road bike when riding up hills.
