Trail runner smashes Everesting treadmill world record
Ty Andrews of Flagstaff, Ariz., achieved 8,848 metres of elevation on a treadmill set to 20 per cent, in a little over eight hours
Just before Christmas, Arizona pro mountain runner and multiple FKT holder Ty Andrews broke the Everesting treadmill world record, climbing the height of Mount Everest (8,848 metres) on a treadmill set to an incline of 20 per cent. He finished in eight hours, 17 minutes, nine seconds, breaking the previous record by almost 39 minutes while raising funds for his foundation (the Chaski Foundation), which supports young athletes in Nepal and Ecuador.
As reported in Outdoor Sportswire, Andrews made the run at the La Sportiva store (his sponsor) in Boulder, Colo., on Dec. 21, surrounded by fans and friends.
Andrews has also announced that, in the spring of 2026, he will attempt to break Kilian Jornet’s speed record on the north (Tibetan) side of the real Mount Everest; Jornet set the record from Base Camp to the summit at 26 hours, in 2017. Andrews made two expeditions there in 2025, attempting but failing to set speed records on the southeastern route (via Nepal).
According to fastestknowntime.com, Andrews holds 92 FKTs in total, most of them unsupported or self-supported. These include numerous routes in Nepal and South America, as well as Tanzania’s Mount Kilimanjaro (in 2023, he set a pair of fastest known times (FKTs) on the ascent, as well as the round trip, making it to the peak in four hours 32 minutes and stopping the clock at the base of the mountain for a final time of six hours, 37 minutes).
Andrews is also an advocate for aplastic anemia, a rare and very serious blood and bone marrow disease he was diagnosed with as a child; he was treated successfully in his home state of Massachusetts and has been in remission for a number of years.
