This is it. The Race of All Races.

In 1994, 150 gutsy riders braved 100 miles of high-altitude, extreme Rocky Mountain terrain — starting at 10,152 feet, climbing to 12,424 feet and pedaling into global cycling history. Today, the Life Time Leadville Trail 100 MTB is one of the most prestigious endurance cross-country MTB events in the world. Every year, a select handful of gritty and determined cyclists make the pilgrimage to Cloud City to Race Across the Sky and take their shot at etching their name among the Leadville Legendary. The red carpet awaits.


The Leadville Trail 100 MTB was first held in 1994 and has since become one of the most challenging and prestigious mountain bike races in the world. Riders take on a grueling 100-mile course that includes about 12,000 feet of elevation gain, reaching a peak elevation of 12,600 feet above sea level at the summit of Columbine Mine. Over the years, top athletes from around the world have come to Leadville for the ultimate test of Grit, Guts and Determination, on their quest for the coveted silver and gold beltbuckle.


Get ready to experience the thrill of the Leadville Race Series like never before! From heart-pumping climbs to exhilarating descents, our videos capture the beauty and challenge of this legendary race. Don’t miss out on the action – check out our 2022 highlight video now and get ready to be inspired!


Head to downtown Leadville for the free, outdoor, open-to-the-public Race Across the Sky Expo. While you check-in and pick up your swag bag, you can give your friends and family a taste of that Cloud City magic. From free swag and bike demos to live podcasts and beer tents, the Expo offers the perfect complement to two of the most prestigious endurance events on the planet.


This is it, the granddaddy of all endurance MTB races. Riders tackle steep climbs and technical descents as they traverse a course that winds its way through some of the most stunning scenery in the country. From the rocky terrain of Powerline to the breathtaking views from the top of Columbine, the Leadville Trail 100 MTB course is a true test of endurance and skill. With a peak elevation of 12,600 feet above sea level, riders must also contend with the effects of altitude as they push themselves to their limits. The Leadville Trail 100 MTB course is not for the faint of heart, but for those who are up to the challenge, it is an unforgettable experience.

  • Member Guaranteed Registration – LT100 RUN & MTB: November 24-30, 2023

This is it, the granddaddy of all endurance MTB races. Get ready for a big day in the saddle. The 104-mile out-and-back course is in the midst of the Colorado Rockies. With a low point, 9,200 feet in Twin Lakes and a high point at Columbine Mine, topping out at 12,516 feet. The majority of the course is on forest rough service roads and high alpine two track with a little bit of singletrack to keep you on your toes. Come prepared, leave as a legend.

The 2023 LT100 MTB course will be identical to the 2021-2022 LT100 MTB course.

Note: The course was modified in 2021 to account for private property owners, as well as safety.


  • Markings – The course will be marked with pink flags and pink and black tape.
  • Vehicles – Obey the rules of the road, as the roads are not closed to traffic.
  • Know the course! – Athletes are reminded that while courses are marked, it is your responsibility to know the course
    • GPX files are available for your use (see above)

Course Diversions or Wrong Turns: if a rider exits the official race course for any reason, they must backtrack and re-enter the course at the same spot they exited. If a rider re-joins the course at any other location than the point of their exit, they will be subject to disqualification.

All buckle times are based on individual rider chip times, as they have been in years past. See the definition of chip time vs. gun time below.

  • 9-hour cutoff time = BIG BUCKLE
  • 12-hour cutoff time = SMALL BUCKLE and official finisher


  • Chip Time – your time starts when you cross the timing mat at the start, and ends when you cross the timing mat when you finish – accounting for all elapsed time on the course.  
  • Gun Time – your time starts when the race starts (6:30am -6:50am).  
  • Reminder – Chip time will be used to determine your belt buckle eligibility and there will be no changes to those times. Gun time will be used for course cutoffs. Cutoff times are based on a 12 hour cutoff for the last corral, White 3. 

NOTE: Top 5 men and women overall times will be based solely on gun time. In the event of a sprint finish for the top 5 overall, riders will be scored in the order in which they cross the finish line. 


  • Race Numbers must be visible at all times, tied to the handlebars of your bike. 

DO NOT cut or fold  your number – this may damage the timing chip and impact your timing data

We recognize crews as a critical component to all of our events. Our courses cover open roads and trails and careful consideration must go into how and where crews and spectators can access their athletes. A conscious plan around this is a foundation of our partnership with the community, USFS, BLM, City of Leadville and Lake County officials to ensure we are providing a safe event experience to everyone involved.

Each rider will be given 1 vehicle hang tag at registration – hang tags should be visible and will have your bib number on it. Only one vehicle per rider will be allowed to travel to aid stations.


There are 3 crew locations: riders will hit each location twice.

NOTE: crewing outside of these 3 locations is against official race rules and will result in disqualification of your rider.

Parking and overall congestion in Leadville will continue to be a crucial topic for everyone this season and for our presence in Leadville moving forward.

  • Leadville temperatures in August vary from daytime highs in the upper 70s to nighttime lows in the upper 20s. Expect sunny mornings and afternoon showers, and be prepared for the Colorado high country’s volatile weather. During the race, it could rain, hail, and even snow. Lightning is hazardous, especially above the timberline. Hypothermia easily occurs with a combination of decreasing temperatures, wind and precipitation. It can result in confusion, and this can be deadly.

    Not in the right corral?

    If you believe that you have a finish time that would place you in a faster corral, here are the steps needed:

    • View our 2023 corral chart for corral assignments and eligible races.
    • Send a screenshot or the direct link to your results to us at for us to verify and consider re-corralling you.
    • You will receive the final word on your corral by August 6th.

    As one of the most well-known mountain bike races on earth, getting into the Leadville Trail 100 MTB has always been difficult. LT100 Qualifiers are long and tough, with lots of climbing. They are similar to the classic course at Leadville in that they consist mainly of rugged jeep roads of gravel and dirt. A qualifier event could not only gain you entry into the LT100 MTB, but it could also boost your corral starting position in the Race Across the Sky!

    Rider starting positions will be organized in color-coded corrals. These positions will be based on a finish time from a previous (see corral chart) LT100 MTB finish/qualifier finish, or if you hold a current USAC or UCI Pro Cross Country Elite license. Please enter finish times or email a current photo of your USAC or UCI Pro Cross Country Elite license when prompted during the registration process. However, if you race a qualifier after previously gaining entry, you MUST email Athlete Services a direct link to your individual results so you will be placed accordingly. You will not be placed automatically. Corrals will be assigned as follows:
