Alex Honnold

On June 3, 2017, Alex Honnold free soloed El Capitan's 900-metre Freerider route — ascending 3,000 feet of sheer Yosemite granite with no rope, no harness, and no protection — in 3 hours 56 minutes. It is widely considered the greatest athletic achievement in the history of climbing and arguably the greatest single act of human daring in modern sport. The ascent was years in the making: Honnold memorised every move on the route, rehearsed individual crux sections hundreds of times with ropes, and waited until he could execute each sequence on muscle memory alone. The documentary "Free Solo," which won the Academy Award for Best Documentary Feature in 2019, brought his extraordinary feat to a global audience. In 2026, Honnold continues to push routes in Yosemite, Patagonia, and Greenland, but the El Cap free solo stands as a singular achievement unlikely to be replicated. His Honnold Foundation installs solar energy in underserved communities globally. He is simultaneously the most fearless and most methodical athlete on this list.
