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.

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.

Help us keep them pristine.

  • 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.
  • No matter the weather, DO NOT attempt the round trip to Columbine Mine without adequate warm and protective clothing. Remember, the Columbine Mine is at 12,600 feet.

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:

  1. View our 2023 corral chart for corral assignments and eligible races.
  2. Send a screenshot or the direct link to your results to us at for us to verify and consider re-corralling you.
  3. 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:
