This marked Andrews' sixth attempt to break the fastest known ascent record on Everest, a feat previously set in 2003 by Nepalese Sherpa Lakpa Gelu with a time of 10 hours and 56 minutes. In his latest successful climb on 28/5, Andrews utilized supplemental oxygen.

If confirmed, Andrews' achievement will be officially recognized in the Guinness World Records system for the Southeast Ridge route, which is the most popular path to Everest's summit. Furthermore, the detailed climbing data will be meticulously stored in the comprehensive Himalayan database.

Andrews is widely known as an athlete specializing in establishing "fastest known time" (FKT) records across a diverse range of challenging terrains. His remarkable dedication to speed and endurance has earned him a prominent place in the world of extreme athletics.

The American athlete has accumulated several notable achievements throughout his career. These include the fastest ascents of Mount Kilimanjaro, encompassing both the summit and the round-trip journey, as well as Mount Fuji in Japan, Aconcagua in Argentina, and Ama Dablam in the Himalayas. He also successfully completed the Salkantay Inca Trail trek in Peru under self-supported conditions, without receiving any external aid or resupply.

In December, Andrews established a world record for "everesting" on a treadmill. This challenge involved running on a treadmill set at a 20% incline, achieving a total elevation gain equivalent to 8,848 meters – the exact height of Mount Everest – during an event held in Boulder, Colorado (US). Everesting, often referred to as the Everest challenge, requires participants to either cycle or run up and down the same slope repeatedly until they accumulate an elevation gain equivalent to Mount Everest's 8,848 meters.

Andrews initially aimed to climb Everest without using supplemental oxygen and made several attempts in 2025. However, these efforts were hampered by severe weather conditions. During one particular attempt, he was merely 400 meters from the summit but was forced to turn back due to a high risk of avalanches and unstable snow. Subsequently, Andrews launched another expedition in the spring, but this attempt also proved unsuccessful, necessitating his evacuation from the mountain by helicopter.

This year's climbing season on Everest has also been marked by numerous new records. According to RTL Today, more than 950 individuals have successfully summited the mountain, a number that is projected to continue rising, potentially surpassing the previous record of 872 people set in 2019. On 21/5 alone, an unprecedented 274 people reached the summit on a single day, marking the highest daily total ever recorded.

The government of Nepal demonstrated its commitment to the climbing community by issuing a total of 494 climbing permits to foreign nationals this season, which represents the highest number ever granted.
