About the Event

This is it: the race of all races. One hundred miles across the high-altitude, extreme terrain of the Colorado Rockies, this event was created for only the most determined athletes. Starting at 10,152 feet and climbing to 12,424 feet, you’ll be challenged to catch your breath—while the views try to take it away.

The Chris Klug Foundation (CKF) has been a charity partner with Lifetime since 2012, raising over $250,000+ for CKF's programs. CKF's Leadville Trail 100 charity team helps to educate others on the facts of organ, eye & tissue donation, while raising awareness for the those awaiting a lifesaving transplant nationwide.
