Book Summary

By one of the fastest runners of her generation, an affecting, brutally honest memoir of elite sports gone wrong—and a clear-eyed call for how parents, coaches, and young athletes themselves can build a healthier youth sports culture.

Few women have ever run 800 meters in under two minutes. Even fewer people have taken on running's abusive training culture and won. Mary Cain has done both.

She emerged as a running phenom at age 12, a straight-A student obsessed with Greco-Roman mythology and the freedom she felt when she ran fast. Like any middle-schooler, she just wanted to fit in, so she learned to run through the discomfort of hard training sessions, and the confusion of her coaches' and teammates' bullying. And she was overjoyed when, at 16, Alberto Salazar called to invite her to train with the famed Nike Oregon Project.

Cain was poised to transform the sport, Salazar told her. She resolved to hold on to his favor, even as he insisted she lose weight and push through the pain of emerging injury. For years, she excelled, setting records against elite runners twice her age. The Olympics were in her sights.

But off the track, Cain was crumbling. She snuck granola bars in the middle of the night and sank into a deep depression as injury after injury set in. Finally, she left the Oregon Project, telling herself she just needed a break. A chorus rang out across the running community: What happened to Mary Cain?

Now, with her suit against Nike behind her, Cain is ready to share her side of the story—and to flip the script on abuse in youth sports. She draws on her diaries from this wrenching period of abuse to show, with clarity we rarely see, how young minds respond to the win-at-all-costs culture that pervades youth sports today. By turns raw, wry, and impassioned, This Is Not About Running is a fierce memoir of the damage wrought when we prioritize competition over mental health.

Can’t out it down memoir
I could not put this memoir down from the moment I read the first two sentences. I knew nothing about the author but after I finished the last sentence of her amazing book I was so in awe of this woman's courage and resilience after years of sports abuse.
Mary Cain was one of the fastest runners of her generation in middle distance events. From middle school on she was outperforming girls older than her.

At the age of 16, she was recruited to be coached by Alberto Salazar at the Nike Oregon Project (NOP), a program designed to cultivate young runners. While the abuse in that program is horrific, her lite as a young runner in middle school wasn't much better.
There while she was not physically abused by dieting and other things, she was bullied by her coach, her teammates and their parents. Jealousy is the key ingredient for that - and even later in competitive racing where opponents snubbed her. In NOP, staff were not qualified like the sports psychologist who only brought on Mary's troubling self loathing as she struggled to lose weight and lost races (usually not placing high enough to make the cut). By the time she left the program she was a shell of who she had been when she first arrived. But due to a NY Times article she helped write, she helped expose the program, regained her dignity, went in to sue Nike, and establish an advocacy group for young girl runners.

While this is a fairly long book, the chapters are short and the language is clear, precise and sharp, making the reading fast. Truly I was mesmerized in the read. This is such a tragic story but told with such honesty. It's a must read for parents who are considering or seeing their children as championship material.
