American endurance athlete and mountaineer Tyler Andrews, a 36-year-old cancer survivor, became the first non-Sherpa climber to hold Mount Everest’s South Base Camp speed record after climbing from Nepal’s 5,364m Base Camp to the 8,848.86m summit in 9 hrs 55 mins on Thursday, completing the ascent after four failed attempts across two climbing seasons — the last less than a week ago. Andrews broke the 23-year-old benchmark of 10 hrs 56 mins set by Nepali climber Lhakpa Gelu Sherpa in 2003, a record that endured through two decades of increasingly commercialised Everest expeditions.

American climber Tyler Andrews broke the previous, long-standing record by just over an hour.

Tyler Andrews, 36, climbed the 29,032-foot peak in just 9 hours and 55 minutes, smashing the record of 10 hours and 56 minutes, his team said.
