Seven Attempts and One Successful Summit: The Long Odds on K2 - Gerlinde Kaltenbrunner

Gerlinde Kaltenbrunner is the first woman to climb the world's fourteen tallest mountains without the help of an oxygen tank at altitude, braving exhaustion and cold through the thin mountain air. But despite her success, she was thwarted on many occasions - it took her seven attempts to summit K2 alone. She had a partner fall to his death and even on her successful summit of K2, she was trapped on the mountain in a two person tent for four days, with a climbing team of four people. Kaltenbrunner tells Boyd about her ordeals climbing K2 and her outlook on preparation for success, and why she no longer climbs the world's tallest mountains.
