Due to the historic snowfall and avalanche debris experienced this winter, we are not able to use many of the iconic trails that make this race so special. Therefore we had to make the tough decision to postpone the race this year. The silver lining is that now we can start planning for next year to create an even bigger and better comeback race to celebrate our 15th anniversary. – Tentatively scheduled for July 18th, 2020.  We will roll everyone’s entry fee over to next year or you can request a refund.

For those who still want to come and enjoy the great riding that is open, we are organizing three days of group rides and BBQ, on Friday-Sunday. More details on that to come.


“You’ve done the rest, now take the test.”

Welcome to Colorado’s premier off-road Ultra race, the 15th annual Breckenridge 100. Part of the National Ultra Endurance Series.

If you’re not ready for the Ultra, then race the Marathon distance 100K, the XC 32, or enter a two or three-person relay team.

Breckenridge 100 Wheeler Pass
Wheeler Pass, Loop 1

Featuring a sprawling course nestled between 3 ski resorts, we’ve linked together an amazing network of backcountry trails and roads that will delight and challenge.

The unique cloverleaf style loops bring you back through Carter Park during the race.

You’ll cross the Continental Divide three times, climb 12,000 foot passes and forge high mountain streams while returning to the support and encouragement of staff and friends who are waiting for you in historic downtown Breckenridge.
