CENTURYLINK LEADVILLE TRAIL 100 RUN presented by La Sportiva

AUGUST 17-18, 2019

2019 event registration details coming soon!

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 CenturyLink Leadville Trail 100 Run presented by La Sportiva was open December 1-31, 2017. Winners were notified in mid-January and automatically charged the $315 registration fee. Entrance into the 2019 race will open December 1, 2018.

You may register for the LT100 Run presented by La Sportiva 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.

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 will return 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.
  5. In 2017, we will again use the Colorado Trail to access Winfield. This will add 2.3 miles and 10 feet of elevation gain to the course. 

Aid Stations
There are 11 well-stocked aid stations along the course. Cut-off times for the aid stations do apply.

Check out the 2018 Athlete Guide for detailed schedules, course information and more.

Awards Ceremony will be held at 12:00 p.m. on Sunday at the Lake County High School gymnasium. All awards and finisher buckles will be presented at this time and must be picked up in person at the Lake County High School gymnasium. Participants who finish before the 25-hour cutoff will receive large buckles, while those that finish before the 30-hour cutoff but over the 25-hour cutoff will receive small buckles.

Awards will not be given to others and will not be distributed before or after the Awards Ceremony. Finisher sweatshirts will be distributed after the awards ceremony at the High School. The first 400 finishers will be guaranteed their sweatshirts the day after the race. If your sweatshirt is not printed overnight, it will be made and shipped to you free of charge. However if you do not attend the award ceremony to receive your award, buckle or sweatshirt, you can visit the Leadville Race Series Store Website to have that product shipped to you. After October 31st, 2018, buckles will no longer be able to be shipped. If you would still like your jacket or award after October 31st, 2018, please reach out to Kelsey Conine (kconine@lt.life) to get that product shipped to you.

*Please note that 2018 awards will not be shipped until the end of our race series season, September 2018.

Your race checklist isn’t complete without your pacers and crew! Give them a way to commemorate this special experience with their own Leadville Race Series memorabilia. Visit our online store to check out our exclusive LRS crew shirts (pictured on right) to get your team prepared for race day!

Pacers are allowed after the 50-mile point (Winfield Aid Station). You may have as many pacers as you wish, although only one pacer at a time (until mile 99). Pacers may be picked up only at aid stations and approved crew points. A pacer must fill out a waiver prior to being on course. The waiver can be filled out at the aid station or you may print one here. The waiver must be turned in at an aid station to receive the proper pacer bib.

Pacing entails patience, tolerance and humor. The primary duties of a pacer include route finding, keeping the runner on pace, ensuring that the runner continues to eat and drink and making sure the runner leaves the aid stations with adequate clothing and supplies to reach the next aid station. Pacers are not allowed to push, pull, carry or tow the runner. Any special pacing situations or requests must be pre-approved by race management.

We strongly suggest you bring someone to crew for you during the race. Your race packet includes a hang-tag which should be displayed and readily visible on the crew vehicle at all times. Your crew is your personal responsibility. If your crew disregards parking instructions, race rules, directions or requests from race officials, you (the racer) will be disqualified from the race. Please make certain that your crew is not the one others complain about. We ask that your crew drive slowly and obey all posted warnings. There will be a Lake County Sheriff’s Officer patrolling road sections.

Crew access into aid stations may be limited. If crews are meeting you at aid stations, they should allow adequate time to park and walk to the aid station. It is your responsibility as a runner to make sure that race officials time you in and out of all aid stations. The race packet includes a map and directions showing access roads and crew access points, and crew and pacer rules. Crews should become familiar with the locations of aid stations, available access roads and race rules prior to the start. . Crewing is restricted to approved locations, which include Pipeline Alternate Crew Zone and all aid stations except Halfpipe and Hopeless (near Hope Pass).

Our races are Zero Waste events. Look for recycle and compost bins at every aid station and start/finish. Please discard any trash in an appropriate container. Intentional littering on the course will be grounds for disqualification. The course—on trails both public and private—travels past many historic sites and through areas of exceptional beauty. Help us keep them pristine.

We will be recycling all plastic, aluminum and cardboard during these races, and all our events. We’ll take care of this at the aid stations. At the start/finish, please ensure you place trash or recyclable materials in the appropriate containers, which will be well marked.

From the very beginning, volunteers have made the Leadville Trail 100 possible. We truly appreciate all that our great volunteers do to make our races run smoothly and to make the racers’ experience unforgettable. If you are going to be in town for the Leadville Trail 100, we would love for you to join the family and pitch in. Thanks in advance for your help — we couldn’t do it without you!
