Karl Egloff

Karl Egloff (born March 16, 1981, Ecuador) is a Swiss-Ecuadorian athlete, mountaineer, cyclist and mountain guide, best known for his speed ascents of high mountains, including the Seven Summits.

He was well known in his native Ecuador for a record speed ascent of Cotopaxi in December 2012, climbing up and down in 1 hour 37 minutes. He came to international attention in August 2014 when he broke the athlete Kilian Jornet's record for a speed ascent of Kilimanjaro, climbing up and down in 6 hours 42 minutes. In February 2015 he also broke Jornet's record on Aconcagua, climbing up and down in 11 hours 52 minutes.

In June 2019 he broke Kilian Jornet's speed record on Denali by a single minute, climbing up and down in 11 hours 44 minutes. A notable feature of this ascent is that while Jornet used skis for his descent, therefore descending much more quickly, Egloff ran and climbed back down again. Provided by Wikipedia
