Sunrise to Sunset – Castle Rock


The Sunrise to Sunset 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 in Castle Rock, 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.

NEW FOR 2022

  • The course will be counter clockwise
  • The start format will be revised. Details coming soon!
  • Get your dance moves on!  That’s right, we are making this year’s event themed “80’s”.  Get your team to dress up and decorate your team area for some sweet prizes.
  • Series point system. More to come!
