Evergreen Mountain Bike Alliance has completed installation of a new adaptive mountain bike (aMTB)-specific trail rating system and signage across the Trek at Tehaleh trail network—marking a major milestone for accessible trail systems in the region.
The Trek at Tehaleh is now the first trail network in Washington State fully signed with accessibility and difficulty ratings for adaptive mountain bikers—setting a new standard for inclusive trail systems and giving riders clearer, more consistent information to guide route selection and decision-making.
The updated signage includes detailed aMTB trail ratings, specific to the build and size of 3- and 4-wheeled adaptive mountain bikes. Each trail sign also provides key details such as trail width and camber, giving riders clearer insight into trail conditions before they ride. A new trailhead sign offers an at-a-glance overview of the system, helping visitors better understand trail options and choose routes that match their equipment, experience, and comfort level.
“This project was built alongside the adaptive community from day one. Their input shaped every detail, and this system is stronger because of it.” - Rob Buck, Evergreen South Sound Chapter President
Evergreen held on-the-ground trail assessments and detailed review with adaptive athletes Jim Martinson, Erin Martin, and several others whose lived experience helped guide the development of the signage system. During these assessments, particular attention was given to the unique dimensions and handling characteristics of adaptive mountain bikes, including required trail width, turning radius, camber, and overall trail difficulty. By incorporating this level of detail into trail signage, the Trek at Tehaleh trail system takes an important step toward creating a more welcoming and navigable experience for all riders.
“As the first fully signed adaptive mountain bike trail system in Washington State, this is a big step forward. It is a clear example of Evergreen’s work to build and support more accessible, sustainable mountain biking opportunities across Washington.” - Eddie Espinosa, Executive Director of Evergreen Mountain Bike Alliance
This work is also highlighted in Evergreen’s new documentary film, For All Riders, which features the Tehaleh trail assessment days and the collaborative effort behind developing adaptive trail standards. The film premiered on April 23 in Seattle, with additional screenings scheduled throughout the spring and summer.
This pilot project was made possible through collaboration and support from Pierce County Parks and Tehaleh. Evergreen's Education, Accessibility, and Trail Stewardship Initiatives has been made possible thanks to a generous grant from the REI Cooperative Action Fund. Evergreen Mountain Bike Alliance is committed to building trail systems that are accessible to a wide range of riders while actively stewarding the landscapes that make mountain biking in Washington possible.
