American climber Tyler Andrews has set a new world record for the fastest ascent of Mount Everest using supplemental oxygen. The 36-year-old managed to traverse the route from base camp at an altitude of 5,364 meters to the summit at 8,848 meters in just 9 hours and 55 minutes, breaking the previous record set by Nepalese Lhakpa Gelu in 2003.
The news was confirmed by David Steven, head of the Asia Trekking company, which organized the expedition. According to him, Andrews reached the "roof of the world" in less than 10 hours, an extraordinary achievement in mountaineering. Although he made the climb alone, the American was assisted by two Sherpa guides, who provided him with oxygen, water and the necessary equipment along the way.
This year's spring climbing season on Everest has seen a record number of climbers. According to Nepalese authorities, more than 950 climbers have reached the summit since the season began on May 13, thanks to favorable weather conditions. Other records have also been broken, including the highest number of ascents in a single day, with 275 people reaching the summit on May 21, and the number of permits issued to foreign climbers, which reached 494.
However, the season has also been marked by tragedy. So far, five climbers – two Indians and three Nepalese – have lost their lives on the slopes of Everest.
