You’ve tried the rest, now take the test!

“You’ve done the rest, now take the test.” It’s waiting for you on Saturday July 14th. 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.
