Due to the recent snowfall and the potential damage to the Aurora Sports Complex, we have been forced to make a venue change to Rhyolite Park located at 1701 Crystal Valley Parkway, Castle Rock, CO 80104.

This proven venue has been used as the location for “Castle Cross” for the last few years. You can look forward to a quality event including a massive flyover, substantial elevation changes, and alot of flow. We also will have an 800 square foot heated hospitality tent, food all day, bike industry representatives showing off sweet gear, a playground for the kids, and the honorable Larry Grossman on the mic. Plus, the weather looks good to boot!

The ACA website and online registration at PreRace.com will be updated shortly. All start times remain unchanged. We look forward to seeing all of you out there with cowbells ringing!
