The most dominant ski racer on the planet is constantly questioning her talents—which may be the secret of her greatness. Mikaela Shiffrin has won two Olympic gold medals and more than 70 World Cup races, but unlike fellow American skiing stars Lindsey Vonn and Bode Miller, she isn’t known for her speed-demon recklessness. Instead, she’s lauded for her perfect form, tactical brilliance, and workaholic approach to training. In this episode, based on excerpts from an exclusive extended interview with Outside for our five-part docuseries, Mikaela Shiffrin: Passion and Purpose, she reveals how underneath all that there’s a burning doubt she has learned to embrace.
