About Us

Push. Pedal. Power.
Welcome to Rattler Racing. It all started for us in 2015. Seeing a serious need for some mid-week mountain bike racing, we set out on creating a summer series. Little did we know how well it would be received. Since then, we've added more XC, some gravel, cross and maybe the occasional stage race and who knows what else. Our mission is to create fun, challenging and memorable events that we would want to do ourselves. After all, we’ve been there, and we will work tirelessly to make our events something you will want to come back to. While it may sound same ol’, customer service is our passion. If you haven’t been to one of our events, come on out. You won’t be disappointed. Send us your comments, ideas, and concerns. We value feedback and want to make our events better every time. See you on the trails!


We put every effort in to cover all the bases and deliver the best race experience.


Enjoy a killer experience with top notch announcing, interviews and music.


Let’s face it, after what you just did, seeing some results is kinda important!

Fangdango moves to a new location in 2023 to a familiar venue. Thanks to the fine folks at the MAC and Castle Rock, this year’s course features some of the old classics near the Phillip Miller Activity Complex.
