Thank you to all the riders and all the wonderful volunteers who made Elephant Rock such a great day. We will have photos up soon!



The Elephant Rock Cycling Festival is the official start to the Colorado cycling season. You will not want to miss the excitement and camaraderie of the 32nd annual pilgrimage to Castle Rock.



Ride day registration will be held at the Events Center at The Douglas County Fairgrounds at the following times:

Saturday, June 1 from 12 – 7 p.m.
Sunday, June 2 from 5 – 9 a.m.

Included with your Registration

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

  • Commemorative item
  • 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)

*Event Lunch and Ride T-Shirt are available for an additional charge.

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!


ALL registrations include a donation to Bikes for Backpacks and youth under the age of 18 ride FREE (for a limited time) on all courses.

We are pleased to introduce a new and improved lunch program that includes a few of Colorado’s finest eateries in Biju’s Little Curry Shop, Park Burger, and Flying Horse Catering. We recognize a post-ride meal is important in recovery and further, it leaves a good taste in your mouth about the event! So this year, we invite you to pre-select your lunch, options that cater to most appetites, to include vegetarian and gluten-free. 

Course Caps

The Elephant Rock will enforce a registration cap on each individual course rather than an overall participant cap. Registrations will not be accepted once the caps are met. Please register early!

Manage Registration

The Elephant Rock participants are able to manage their registration details online until May 8. Riders can change their t-shirt size, course preference, and other custom questions. It’s simple to make changes – just log in and edit your preferences via the confirmation link. Participants are not allowed to change their name, address or any way transfer a registration to somebody else.

Course Change

Participants can change their course until May 8. Participants will be charged the price difference in course selection.


In true cycling tradition, the Elephant Rock will take place regardless of weather; therefore refunds will not be provided.
