About Leadville Trail 100

Sat, Aug 16, 2025 • Leadville, CO
This is it. The Race of All Races. Where it all began. Across the mighty peaks of the Colorado Rockies, a legendary wind whistles. Immersed in 10,000+ feet of Cloud City magic, Leadville calls. Pacers can pick up their runners at any point on course beginning at Twin Lakes inbound at mile 62. You may have as many pacers as you wish, although only one pacer at a time (until mile 99). Pacers may act as burros, to carry food and equipment for their runner. Pacers are not allowed to push, pull, carry or tow the runner.
