Karl Egloff


Karl Egloff 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 the volcano 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.

Early life and education

Born and raised in Ecuador to a Swiss father and Ecuadorian mother, he climbed mountains from an early age, assisting his father with his mountain guiding business from the age of 15. When he was 17 he moved to Zurich, Switzerland to study for a degree in business administration. While in Switzerland he served in the Swiss Army and tried unsuccessfully to train as a professional footballer.
At the age of 25 he returned to Ecuador and established his own mountain guiding business. He took up mountain biking and raced with the Ecuador national team for two years.

Mountaineering

In 2012 he began focusing on guiding and climbing, and began doing speed ascents of mountains.
