Evergreen Today

With Seven Regional Chapters, 17,000 + followers and 3200+ members, the nonprofit Evergreen Mountain Bike Alliance is Washington State’s largest mountain bike organization. Internationally known for developing Colonnade and Duthie Hill mountain bike parks, Evergreen is dedicated to trail building and maintenance, advocacy and education. Created in 1989 as BBTC, Evergreen was originally a grassroots solution to local trail networks closing to riders.

It is Evergreen's goal to make Washington one of the best places in the country to ride a mountain bike. How? By…

  1. Working with landowners and land managers to create and ensure access to trails.
  2. Donating thousands of trail building and trail maintenance hours to make sure we always have stellar trails open to ride.
  3. Educating mountain bikers through rider skills classes and trail building clinics so we can grow our voice and power to get more done.
  4. Getting more kids out riding via our classes and education programs
  5. Offering events, races and club rides to help mountain bikers get together, and get out and ride!

Our History

In 1988 several mountain bicyclists joined together in response to trail closures that were rapidly occurring in the Northwest. This group, originally called Concerned Off Road Bicyclists Association (CORBA), officially incorporated with Washington State as a non-profit in April 1989. By the spring of 1990 another mountain bike group had formed, the Backcountry Bicycle Trails Club (BBTC), which was also working on mountain bike access issues. By June 1990 these two groups merged and adopted the latter name. In 2008 BBTC was renamed Evergreen Mountain Bike Alliance.

Originally oriented towards political advocacy, the organization expanded over the years to include education and recreation opportunities. Thousands of riders have acquired trail maintenance skills, responsible riding techniques, and trail safety knowledge through the trailwork parties, classes, communications, and group rides offered year-round.

As an organization, we are proud of our successful shift from a reactive stance, fighting for public trail access, to a proactive approach geared towards building positive, cooperative relationships with federal agencies, public & private land owners/managers, environmental organizations, and other trail user-groups – all while consistently taking care of the trails we ride on!
