Ty Andrews Shatters Everest Treadmill World Record, Announces Spring 2026 Everest North Side Speed Attempt

December 29, 2025

BOULDER, Colo. (December 29, 2025) /OUTDOOR SPORTSWIRE/ — Professional mountain athlete Ty Andrews (La Sportiva, Chaski) broke the world record for fastest time to climb the height of Mount Everest (8,848 meters or 29,029 ft.) on a treadmill, simultaneously announcing his return to Mt. Everest in spring 2026. Andrews completed the challenge in 8 hours, 17 minutes, and 9 seconds at the La Sportiva store in Boulder, Colorado on Sunday, December 21, in front of an enthusiastic crowd of supporters and fans attending in person, as well as a massive online audience tuning in from dozens of countries. The effort shattered the previous 12-hour record and has raised over $25,000 for youth athletic programs in Nepal and Ecuador through the Chaski Foundation.

The record attempt also served as the official launch of Andrews’ return to the real Mt. Everest, with an upcoming spring 2026 expedition to establish new speed records on Mount Everest’s North Side without supplemental oxygen. Andrews will chase acclaimed mountain and ultra runner Kilian Jornet’s North Side record of 26 hours from Base Camp to Summit (set in 2017), while simultaneously establishing a new round-trip record for Base Camp-Summit-Base Camp in a single, ultra-marathon push. This will be his third Everest expedition and his first attempt on the mountain’s North Side from Tibet.

“Breaking this treadmill record was about proving to myself—and to the young athletes we support through Chaski—that pipe-dream goals become possible through preparation, persistence, and community support,” said Andrews. “Now, we’re taking that same mindset to the North Side of Everest in the spring.”

Andrews, who holds over 90 mountain speed records, including records on Manaslu (8,163m), Kilimanjaro (5,895m), and Aconcagua (6,962m), previously set world records on a treadmill for the half marathon (2014) and 50 kilometer run (2020).

“This is what happens when performance meets purpose,” said Chaski Foundation representative Conor Sleith. “Ty didn’t just break a world record, he brought our entire community together for something bigger than sport.”

Andrews, a childhood cancer survivor, has been running professionally for more than a decade and combines world-class athletic performance with coaching, guiding, and philanthropic work supporting youth sports development globally. His spring Everest expedition will be the subject of an upcoming film to be released in late 2026.
