Breck 100

Welcome to Colorado's premier off-road endurance race, the Breckenridge 100 Cross Country Mountain Bike Challenge in Breckenridge, Colorado. Featuring Solo and Three Person Team Competitions, this incredible course climbs 13,719 feet over its 100 miles and will remind you of what backcountry mountain biking is all about. With Solo and Team categories, this is a perfect opportunity for you to expand your boundaries.

Featuring an inspiring, sprawling course nestled between 3 ski resorts, participants will face a unique challenge of strength and fortitude. The distinct clover-leaf loops offer team competitors the opportunity to strategize their efforts and pick which loop each participant will tackle. The renowned course architect has linked together an amazing, interconnecting network of backcountry trails, dirt roads, double track and bike paths that will take you far beyond the typical boundaries of endurance racing. 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 all the time returning to the support and encouragement of the staff, friends and teammates who are waiting for you at Carter Park in historic downtown Breckenridge.
