Well that was an absurd amount of fun, racing from 7 a.m. to 7 p.m. on the flowing trails at Philip S. Miller Park. Thanks to the adults for racing and supporting the Colorado High School Cycling League - and thanks to the high schoolers for showing us how it's done on the trails!


The Sunrise to Sunset Elephant 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 again on the flowy trails at Philip S. Miller Park in Castle Rock, this amazing $30M facility offers the perfect endurance mountain bike venue less than a mile from the Colorado Bike Expo and Elephant Rock Cycling Festival.  The playful 6.5-mile course is cut into to the hills and drainages surrounding the park and offers ample viewing from the staging area for team members and spectators.
