Gymnast Katrin Davidsdottir will talk about her new memoir, Dottir, at Brookline Booksmith, Thursday, August 29, at 7 pm.

As one of only two women in history to have won the title of “Fittest Woman on Earth” twice, Katrin Davidsdottir knows all about the importance of mental and physical strength. A gymnast as a youth, Davidsdottir wanted to try new challenges and found a love of CrossFit. But it hasn’t been a smooth rise to the top. In Dottir, the author shares her journey with readers, detailing her focus on training, goal setting, nutrition, and mental toughness.

Katrin Davidsdottir is a former gymnast from Reykjavik, Iceland. She is the third person to ever win the CrossFit Games twice, and only the second woman to do so. She is currently training for next year’s Games in Natick, Massachusetts.
