Sasha DiGiulian is the best female climber in the world. In 2012, she became the first American woman (and only the third woman of all time) to climb grade 5.14d, only three steps below where the scale tops out. She’s graced the covers of 12 different magazines, received the Rubicon and Salewa Rock Legend awards and been sponsored by Adidas, Five Ten and Petzl, among others. The craziest part? She’s only 21. We caught up with the Columbia University undergraduate to talk about climbing, philosophy and piña coladas.
