Tyler Andrews Returns to Everest for Fall 2025 Speed Record Attempt

Himalaya, Nepal – July 22, 2025 – Professional mountain athlete Tyler Andrews (La Sportiva / CHASKI) has announced his return to Mount Everest this October to attempt the speed record for ascending the world's highest peak (8,848m/29,029 ft.) without supplemental oxygen. This follows an attempt in spring 2025 that came within 350 meters of the summit.

Andrews will target the current record of 20 hours, 24 minutes from Base Camp to Summit, set by Kazi Sherpa in 1998. The American holds over 85 mountain speed records including recent marks on Manaslu (8,163m), Ama Dablam (6,812m), and peaks across six continents.

"After coming so close in the spring, I walked away confident this record is within my capabilities," said Andrews. "The fall season presents different challenges but also unique advantages—namely having the mountain essentially to ourselves with only about a dozen people total versus over 1,000 in spring."

The October attempt, part of "Project Himalaya: Run Everest," will feature a streamlined approach with Andrews climbing solo supported by expedition leader Dawa Steven Sherpa of Asia Trekking  and minimal infrastructure. This represents a significant tactical shift from the spring attempts, emphasizing self-sufficiency and reduced complexity.

"The fitness is the easy part," Andrews noted, referencing feedback from mountaineering professionals. "The challenge is managing all the variables on the mountain itself. We're simplifying everything to reduce points of failure."

The expedition will benefit the Chaski Foundation, Andrews' 501(c)(3) nonprofit supporting athlete empowerment and environmental projects in Nepal and the Andes. The team aims to raise $100,000 through the attempt.

Andrews, a survivor of childhood Aplastic Anemia, transitioned from professional road running to mountain athletics following personal challenges in 2020. His 2024 breakthrough season included shattering the Manaslu speed record by over two hours and setting six additional world records in the Nepali Himalaya.

The fall climbing season presents unique conditions including more snow accumulation but significantly reduced crowds, allowing optimal weather window selection. Andrews plans to depart for Nepal in mid-September with the summit attempt scheduled for early October.
