With only about a dozen ascents in nearly four decades, the Slovak Direct route on Denali's south face is one of North America's premier hard climbs. Sixteen years after the first ascent, Scott Backes, Steve House, and Mark Twight famously upped the ante by climbing the route in single-push style: bringing no tent or sleeping bags and climbing nearly continuously for 60 hours. Twenty-two years later, in the spring of 2022, the Slovak saw another round of single-push ascents, blazing up the route in less than 24 hours. For this episode, AAJ editor Dougald MacDonald spoke with climbers from all three of these ascents: Steve House, Matt Cornell, and Rob Smith. They talked about the progression in climbing gear and tactics that allowed such amazingly fast climbs, but also about universal aspects of challenges like this that have nothing to do with speed records.
