2025 CKF Leadville Trail 100 Run

Get ready to join the ranks of the extraordinary as you tackle the "Race Across The Sky" 100-mile run. This isn't just a race – it's a legendary challenge that has been pushing boundaries since 1983. Feel the thrill of conquering the Colorado Rockies, pushing from elevations of 9,200 to an awe-inspiring 12,600 feet.

Join forces with the Chris Klug Foundation's Trail Run Team, our proud charity partner since 2012. Together, not only are we running for glory, but we're also racing towards a noble cause – educating and raising vital awareness for organ, eye, and tissue donation. Be a part of a movement that has already contributed over $250,000 in support of those waiting for life-saving transplants. Embrace the mountain, earn your respect, and run for a reason that extends far beyond the finish line.
