Trailhead CrossFit

Trailhead CrossFit is home to a diverse community of all ages, skill levels, orientations, beliefs, nationalities, and professions focused on becoming the healthiest version of themselves through world-class fitness and nutrition.

We do this by utilizing the CrossFit methodology, hard work, and a commitment to consistency. And through the power of community we are able to achieve growth, leading to long-term, sustainable results.

Why do we do this?

Family | Fitness | Community | Outdoors

These four elements define Trailhead CrossFit’s “why”. We want to be able to truly live life well into our 80’s and 90’s, enjoying shared experiences with family and community. Engrained in the Colorado way of life is the outdoors, and Trailhead CrossFit’s community yearns for these adventures. We look forward to working out in an environment that trains hard and holds each other accountable. We celebrate each others successes and support each other through the struggles.

This is Trailhead CrossFit.
