Big wall climbing is about as relatable as space travel to the average human. To whit: When Sasha DiGiulian and her partner Elliot Faber attempted the audacious Platinum route, they planned to spend 15 days on the massive wall. Then, 2,600 feet up, a freak winter storm pinned them inside their tiny portaledge tents for nine full days. But just because Sasha has the skill to get herself into that bonkers situation and the focus and pain tolerance to make it out—her and Elliot ultimately completed the climb in 23 (?!) days—doesn’t mean she herself is unrelatable. In fact, in a career racking up one of the most impressive big wall resumes in climbing, Sasha has developed a remarkably simple recipe for success. Fortunately for you, understanding it is a lot easier than hanging off a massive cliff for over a week.
