The Subaru Elephant Rock Cycling Festival is the unofficial start to the Colorado cycling season. You will not want to miss the excitement and camaraderie of the 24th annual pilgrimage to Castle Rock for the Rocky Mountain region's premier cycling festival, a Rocky Mountain tradition.

Whether you are six or sixty, prefer to ride on the road or the dirt, there is a course for cyclists of all abilities. All of the rides start and finish at The Douglas County Fair Grounds in Castle Rock. After a day in the saddle, plan to stick around for the Party at the Rock post-ride picnic and cycling expo. Whichever course you choose, you're sure to have a Erockin' good time,

Or, Kick-off the weekend by joining solos & teams at beautiful Greenland Open Space for the 6th annual OPTIC NERVE 24 HOURS of EROCK.

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

• Refreshments and support throughout each of the rides
• a ticket to the post-ride picnic
• a specially designed 100% cotton 2011 Subaru Elephant Rock T-shirt
• a specially designed REI / Subaru Elephant Rock water bottle
• a bag of goodies from our many sponsors
• a chance to win dozens of valuable prizes
• VIP pricing on Subaru cars
• Bike number and Wristband (see below)

All riders will receive a bike number and wristbands. You must wear your event wristband at all times. Your wristband will give you access to the courses and refreshments at the aid stations as well as act as your ticket to the BBQ lunch and prize drawings at the post party.

Your bike number should be attached to the top tube of your bike. Colorado State Patrol has the authority to remove anyone without a bike number off the course you could face potential criminal charges.
