“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.
