Leadville Trail 100 Run

The LT100 Run course is a brutal out-and-back ultramarathon that will push even the toughest runners to their limits. The course starts and finishes in Leadville, but the true challenge is the rugged and unrelenting terrain along the way. The course includes steep climbs of Powerline, high-altitude passes like Sugarloaf, and technical terrain on the Colorado Trail, all amounting to over 18,000 feet of elevation gain. The course reaches a peak elevation of 12,600 feet above sea level on the crux of the course, Hope Pass, where runners will gasp for breath and question their sanity. The LT100 Run race course is not for the faint of heart, but for those who are up to the challenge, it is an unforgettable experience.
