From the Organizer

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.

About This Sport

Endurance Grid is here to help you understand the sport, decide if it's the right fit, and learn how to prepare. For course distances, logistics, and race-day specifics, always defer to the race organizer's event page.

Mountain biking takes place on singletrack and natural terrain where reading the trail matters as much as fitness — cornering, braking, and instinct on dirt are skills that only come from time in the saddle.

Events range from beginner-friendly cross-country races to technical enduros, and the trail community is one of the most welcoming in endurance sport.

Mountain Bike

XC races, enduros, and fat bike events across U.S. trails. Technical, physical, and completely different from anything on pavement.
