About 2025 CKF Leadville Trail 100 Run

The legendary “Race Across The Sky” 100-mile run is where it all started back in 1983. This is it. The race where legends are created and limits are tested. One hundred miles of extreme Colorado Rockies terrain — from elevations of 9,200 to 12,600 feet. You will give the mountain respect, and earn respect from all.

The Chris Klug Foundation has been a charity partner with LifeTime's MTB100 since 2012, raising $250,000+ for CKF's programs. Now, in its third year with a Trail Run Team: the team helps to educate others with the facts of organ, eye and tissue donation, all while raising awareness for the need to help those on the lifesaving waitlist.
