The legendary “Race Across The Sky‚Äù 100-mile run is where it all started back in 1983. This is it. The race where legends are created and limits are tested. One hundred miles of extreme Colorado Rockies terrain , from elevations of 9,200 to 12,600 feet. You will give the mountain respect, and earn respect from all.
The 100-mile out-and-back course is in the midst of the Colorado Rockies. Low point, 9,200 feet; high point is Hope Pass, 12,600 feet. Majority is on forest trails with some mountain roads. Pacers allowed after the 62-mile point.
Since 2008, there have been six changes made to the Leadville Trail 100 Run course. The course was unchanged for many years before 2008. In 2017, we returned to the course that was last used in 2012.
There are 13 well-stocked aid stations along the course. Cut-off times for the aid stations do apply.
