Boulder Mountain Bike Advocacy


The Boulder Mountainbike Alliance's mission is to serve as a positive voice for mountain biking in the greater Boulder Colorado area by improving the trail experience for all users through social rides and events, advocacy, and trail building.

Great communities build trails, and great trails build community.

To fullfill this mission, the Boulder Mountainbike Alliance works towards three major goals:

  • Create a Community of Mountain Bikers
  • Advocate for Trail Access
  • Build and Maintain Trails
