Sunrise to Sunset Castle Rock

Sunrise to Sunset Castle Rock is designed to offer recreational and competitive cyclists the opportunity to compete in a fun and rewarding 12 hour endurance race on a moderately technical off-road course. Register as an individual or form a team that loves to shred for a memorable day of racing, camaraderie and laughs.

Taking place on the flowy trails at Philip S. Miller Park, this amazing facility offers the perfect endurance mountain bike venue less than a mile from downtown Castle Rock.  The playful 6.5-mile course is cut into the hills and drainages surrounding the park and offers ample viewing from the staging area for team members and spectators.
