Due to COVID-19, for the first time in our 33-year history we are tentitively rescheduling Elephant Rock Ride.  Rather than kicking off the cycling season in June, this year we will close it out with a fall spectacular in Parker, Colorado (only 20 minutes from Castle Rock).

Included with your Registration

In addition to a great experience riding some of Colorado’s most scenic countryside, each participant will receive:

  • Commemorative T-Shirt
  • Post Ride Lunch
  • Refreshments and support throughout the ride
  • Goodies from our many sponsors
  • A chance to win dozens of valuable prizes
  • Bike Number and Wristband (see below)
  • Opportunity to participate in friendly time segments (if applicable)


Before you Register, please consider:

  • Tandems are allowed on all courses, but each rider on the tandem bicycle must register separately.
  • All riders will receive a bike number and bike plate. You must wear your event bib number at all times. 
  • Your bike plate should be attached to the top tube or handlebar of your bicycle. Colorado State Patrol has the authority to remove anyone from the course without a bike number. Failure to adhere to this policy could result in both organization ramifications and legal charges.
  • You must wear your helmet at all times while riding. Protect your rock!
