This product is a guide to living one's best life through the lens of track and field, specifically the 400-meter race.

The author, Sanya Richards-Ross, is a world-class runner who has dedicated her life to mastering every phase of the race, from push to poise.

Through her journey, she reveals the importance of measuring one's life in seconds, but not just in terms of time.

Rather, it's about becoming the best version of oneself.

The book shares triumphant and heartbreaking stories of Sanya's career, including her devastating injury during the 2016 Olympic Trials, which forced her to retire from the sport just weeks before Rio.

Despite this setback, Sanya found a way to use it as an opportunity to grow and become the best version of herself.

The book is a powerful reminder that success is not just about winning races or achieving certain milestones, but rather it's about becoming the best version of oneself.
