About CrossFit Beaver Menace


Our Mission is to make CrossFit Beaver Menace, located in Castle Rock Colorado, the premiere CrossFit facility in the Castle Rock area.  

Joining a gym can be intimidating, but at CrossFit Beaver Menace it's a fun and friendly environment dedicated to you. Each workout is explained by certified coaches and scaled ensuring proper form and safety for your fitness level.

''Love our coaching staff, they care and want us to be the best!''
''Coaches know what your body is capable of even when you don't... Athletes pause their training just to help you breathe... Coaches coach form issues & life issues... People are genuinely happy to see you... Lifelong friendships are forged here.''


One of our most decorated coaches, Becky Harsh, has a very imaginative son.  In art class his super hero tshirt said 'I am the Beaver Menace'. Enough said.  

Many of our coaches and athletes started as far back as 2007 at CrossFit 5280 here in Castle Rock.  It was the first CrossFit gym in Douglas County and one of the first 100 CrossFit affiliates in the world!  

With our new gym, we are reaching back to our roots and kickin' it old school where owners are athletes.  Our goal is to create a gym where community and family are a priority.  We have small class sizes and our members consider this a second home where they can hang out before and after a WOD.
