Summary
The chapter opens on Day Three of the bike tour (Poughkeepsie to Hudson, 43 miles). Abby leads the group through tricky roads and a detour, fixing Ted’s flat tire and watching Lily struggle uphill while her daughter Morgan rides ahead with Andy. The weather turns hot and windy, slowing the pace. Abby’s thoughts drift to her recent rude treatment of Sebastian and her decision to let Mark’s call go to voicemail. Riding beside her mother Eileen, Abby flashes back to how she reconnected with Mark in Philadelphia. She recalls volunteering at Camp Kensington in the city’s drug-ravaged neighborhood and recognizing Mark Medoff, her summer-camp boyfriend from Camp Golden Hills, now a doctor who had lost half his weight through gastric bypass surgery. Over coffee and a walking tour, Mark reveals he broke up with his grad-school girlfriend and moved to Philadelphia. Abby describes her own body-positive philosophy; Mark seems to accept it but later displays subtle discomfort with her eating habits. Their courtship unfolds over weeks—dinners, hand-holding, a careful first night together. Abby spends more time at Mark’s pristine apartment, feeling her own life is temporary. She meets his parents, attends holidays, and settles into a comfortable but stagnant relationship. Although Mark would marry her, Abby hesitates, sensing the relationship follows a preordained path. Her hesitation crystallizes when she sees Sebastian again in New York. Back on the trail, Sebastian gets a flat tire. Abby offers help; he refuses but eventually accepts. Lincoln teases him. After the repair, Sebastian asks Abby to ride with them, but she declines, counting the remaining days until Buffalo.

- Wind and weather as emotional reflection: The sticky headwind and cloudy sky mirror Abby’s guilt and shame about Sebastian and her hesitation with Mark.
- The flat tire as a forced pause: Sebastian’s breakdown forces Abby to stop and interact with him, breaking her strategy of avoidance.
Why This Chapter Matters
This chapter is pivotal because it reveals the full history of Abby and Mark’s relationship, explaining why Abby feels so torn. It deepens the contrast between safety (Mark) and excitement (Sebastian) and shows that Abby’s indecision is not new—it has been building for two years. The flashback also introduces the book’s central tension around body image: Abby’s commitment to size acceptance versus Mark’s surgically altered body and the societal approval that grants him. By the chapter’s end, Abby is counting the days until the tour ends, but she has made no decision, keeping the central conflict unresolved.
Study Questions and Answers
-
Why does Abby feel that being with Mark is like “stepping onto a treadmill that was already in motion”?
Abby feels that following her brother to college and moving into her sister’s former apartment set her on a predetermined life path. Reuniting with Mark feels like the natural next step—a ready-made answer to what she should do with her life and who she should love. She enjoys the comfort but also senses that the journey lacks her own choices. -
How does Mark’s past weight loss affect his relationship with Abby, based on the evidence?
Mark had gastric bypass at 19 and now eats carefully, removing breading from chicken and avoiding rice. He gives Abby a drawer and a fridge shelf but subtly moves her ice cream to the back and thins his lips when she orders pasta. Abby notices these signals and decides to keep her treats at her own apartment, showing that Mark’s transformation creates an unspoken barrier between their eating habits and body attitudes. -
What does the flat tire scene reveal about Abby’s feelings toward Sebastian?
Even while Sebastian struggles and curses, Abby finds him “annoyingly attractive” and feels sorry for him. After he apologizes, his low intimate voice triggers a memory of the night they were together, making Abby blush. She declines his invitation to ride together, but her deliberate avoidance shows she is still powerfully drawn to him.
