Race Description
The iconic CKF Leadville Trail 100 Run is set to take place from August 16 to August 17, 2025, in Aspen, Colorado. This 100-mile race, known as the "Race Across The Sky," has been a hallmark of the endurance running community since its inception in 1983, providing a challenging course through the rugged terrain of the Colorado Rockies.
The event is not just a test of endurance; it also serves as a platform for raising awareness about organ, eye, and tissue donation through the Chris Klug Foundation. This partnership has raised over $250,000 for the foundation's charitable programs since it began in 2012, further emphasizing the event's commitment to community and health causes.
