Karl Egloff's latest challenge is an extreme, globetrotting test of climbing ability. The 44-year-old speed climber has set multiple fastest time records in his career and now has his sights on a fresh challenge: to snag the speed records for the tallest mountains in each of the world's seven continents.
He already holds the records for the fastest ascents of the tallest mountains in Europe, Africa, and North and South America, having scaled Elbrus, Kilimanjaro, Denali and Aconcagua in record times.
