About

In 1983, 45 tough-minded runners braved 100 miles of high-altitude, extreme Rocky Mountain terrain — starting at 10,200 feet, climbing to 12,600 feet and running into global endurance history. Today, the Life Time Leadville Trail 100 RUN presented by La Sportiva is one of the oldest, most storied endurance running events in the world — with not one, but two climbs on the crux of the course: Hope Pass. 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 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.
