Kara Winger, three-time Olympian and 8-time U.S. National Champion, is one of the best at what may be track and field's most idiosyncratic sport: javelin throwing. Kara talks about her mental game, and how it helps her set big but achievable goals. And with a degree in fitness, nutrition and health, she's refreshingly open and insightful about weight and body image in sport. She talks about how her views have evolved & about how it felt to hit a new milestone when she stepped on a scale last spring.
