2022 Registration opens December 1st, 2021 at 10am MST!

There are limited spots, but we will hold a waitlist.

Show the world what you’re made of with the Lead Challenge by racing in our progressive series of trail run and mountain bike events ranging from 26.2 to 100 miles for a total of 282.4 miles.


Join Waitlist!

Leadman & Leadwoman entrants will compete in the following events:

*Silver Rush Run times are recalculated to account for running pace vs mountain bike pace.  The formula is the run time x 0.57.  If an athlete does the run and the mountain bike, the faster of the two times will be used for Leadman / Leadwoman scoring.

NOTE:  Leadman athletes will be allowed to use their Silver Rush Run time (calculated as stated above) to adjust corrals.  Please reach out to Athlete Services via email after the event to have your corral adjusted.

Racers must complete each event within the allotted cut off time in order to move on and be eligible for the next. If a racer does not meet the required finish time, he or she will not be allowed to continue in the Leadman competition. However, the racer may continue racing as an individual by notifying Athlete Services via email. Each event must be attempted, failing to start any of the events will disqualify the athlete from all remaining events in the series. The Leadville Race Series does not allow refunds, transfers or deferment in the midst of the Leadman competition.

COST FOR 2021 ENTRY: $1200

*Cost to add Silver King & Queen (participating in both the MTB and Run) is an additional $100 and will be available during the registration process.

Although we look forward to seeing you at our events, we understand certain things may come up that prevent you from attending. Check out our deferral tiers for each event and please let us know if you have any questions!
