Leadville Trail Race Series

Leadville Trail 100 Run

The Leadville Trail 100 Run Lottery is now closed.

Check out our Charity and Camp + Entry options for entry.


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.

Entrance into the 2018 Leadville Trail 100 Run will be open December 1-31, 2017. Winners will be notified in mid-January and automatically charged the $315 registration fee.

You may register for the LT100 Run lottery as an individual or a group. A maximum of four family members, friends or teammates can click the group registration option. Group members will register individually, but be sure to use the exact same group name to signify being part of a group. This will guarantee that either your entire group will be successful in the lottery, or not, assuring that no one will be left out! Please note that if a member of your group has earned preference in the lottery through volunteering, or completed the LT100 Run under the designated sub-30 cut-off time 10 or more times, they will be forfeiting their preference in the lottery.

We will announce the results of the Lottery and open registration for the Qualifier Events in Mid-January.

If unsuccessful in the lottery process and you still wish to participate in the LT100 Run, please check out our qualifier events, Training Camp entries, coaching package opportunity and charity slots available.
