Katie Bono sets probable women’s speed record on Denali at 21 hours, 6 minutes
On June 13-14, Katie Bono completed a round-trip ascent of Denali’s West Buttress in 21 hours, 6 minutes. This is likely a female speed record, and it is the third or fourth fastest known time overall. Bono made the ascent in difficult conditions with heavy wind and drifting snow that forced her to break trail on the way up and down, sometimes navigating in a whiteout. She sustained mild frostbite to her face.
