Lauren Fleshman has grown up in the world of running. One of the most decorated collegiate athletes of all time and a national champion as a pro, she was a major face of women’s running for Nike before leaving to shake up the industry with feminist running brand Oiselle and now coaches elite young female runners. Every step of the way, she has seen the way that our sports systems—originally designed by men, for men and boys—fail young women and girls as much as empower them. Written with heart and verve, Good for a Girl is a joyful love letter to the running life.

Kara Goucher grew up with Olympic dreams. She excelled at running from a young age and was offered a Nike sponsorship deal when she graduated from college. Then in 2004, she was invited to join a secretive, lavishly funded new team, dubbed the Nike Oregon Project. Coached by distance running legend Alberto Salazar, it seemed like the opportunity of a lifetime. Kara was soon winning a World Championship medal, going to the Olympics, and standing on the podium at the New York and Boston marathons, just like her coach. But behind the scenes, Salazar was hiding dark secrets.

When Des woke up on April 16, 2018, the morning of the Boston Marathon, it was 39 degrees and raining, with high, gusty winds. The weather didn’t bother her. In fact, she thought it might be a blessing. She was far from peak form—recovering from illness and questioning her running future—and didn’t expect much of herself that day. But as she ticked off mile after mile in the brutal conditions, passing familiar landmarks on the course she knew and loved, something shifted. Opportunity unexpectedly presented itself. Des tapped into her inner strength and found a reason to race.

The road from a high school track to an Olympic starting line is long and sometimes shadowy. Obstacles like chronic injuries, under-fueled nutrition, and coercive coaching can threaten to derail careers before they’ve even begun. Frustrated by seeing young talent burn out before reaching their potential, professional distance runner Molly Huddle and college coach Sara Slattery have teamed up with trailblazing running legends and sports medicine professionals to create an essential guide to reach your running potential.

Because most nutrition products and training plans are designed for men, it's no wonder that so many female athletes struggle to reach their full potential. ROAR is a comprehensive, physiology-based nutrition and training guide specifically designed for active women. This book teaches you everything you need to know to adapt your nutrition, hydration, and training to your unique physiology so you can work with, rather than against, your female physiology.
