Yes Leadville Trail 100 Run

August 21, 2021
Leadville, Colorado
100M

The legendary “Race Across The Sky” 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.

Course history

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. 

  1. County Rd 11A/Halfmoon Road to Twin Lakes Firestation. Halfmoon aid station was moved in 2009 due to a helicopter crash just before race day. Runners went a short way up Halfmoon Road then turned left onto Pipeline road. This change removed .3 miles from the full course distance and reduced the elevation gain by 750 feet.
  2. Halfmoon Road removed entirely in 2012. The access to Pipeline Road was rerouted past the gravel pits, adding about .7 miles to the round-trip distance and about 50 feet more elevation gain.
  3. Winfield Road/Colorado Trail change in 2012. The Winfield Road was finally removed from the course with the completion of the Colorado Trail into Winfield. This added 2.2 miles to the full-course distance and 365 additional feet of elevation gain.
  4. In 2013, a portion of the Colorado Trail near Winfield was removed. (View a map of the change). With a course distance about 2.7 miles longer in 2012 than in 2008, 2.3 miles and about 10 feet of elev gain were removed from a portion of the Colorado Trail near Winfield.
