Welcome to Colorado’s premier off-road endurance race, the 12th annual BRECK 100. This incredible course climbs 13,719 feet over 100 miles. Not quite ready for the Ultra 100? Challenge your abilities and ride the B-68 Marathon, the B-32 XC, or enter a two or three-person relay team!
The test is waiting for you on Saturday July 16th. Featuring a sprawling course nestled between 3 ski resorts; participants are treated with a unique combination of beauty and challenge. The unique cloverleaf style loops bring you back through Carter Park before embarking on your next challenge.
We’ve linked together an amazing network of backcountry trails, roads, double track and bike paths that will take you beyond your typical boundaries. From start to finish, you will be both pampered and pushed to your limit at the same time. 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, friends and teammates who are waiting for you in historic downtown Breckenridge.
