U.S. climber Tyler Andrews reached the summit of Mount Everest on Thursday in a record nine hours and 55 minutes [1].
The achievement marks the first time in 23 years that the speed-ascent record has been broken. Andrews, 36 [5], overcame a history of cancer and previous failed attempts to complete the climb [1, 2].
The 29,032-foot peak on the Nepal-China border is one of the most grueling environments on Earth [4]. Andrews' time surpassed the previous record of 10 hours and 56 minutes [2], which was set in 2003 [6]. That previous mark was held by Lhakpa Gelu Sherpa, a Nepali climber [3].
This ascent was the culmination of a two-year pursuit by Andrews to break the speed record [1, 2]. His journey involved rigorous preparation to ensure he could sustain the pace required to beat the long-standing mark.
Speed records on Everest are rare due to the extreme altitude and the physical toll the "death zone" takes on the human body. Most climbers take several days to reach the summit from base camp, making a sub-10-hour ascent an exceptional feat of endurance.

The breaking of a 23-year-old record suggests an evolution in high-altitude athletic training and recovery. By successfully summiting after surviving cancer, Andrews demonstrates the potential for elite physical performance following severe medical adversity, while the significant reduction in time highlights the increasing specialization of speed-climbing on the world's highest peaks.
