Building a Bold Future for Mountain Biking in Boulder
At Boulder Mountainbike Alliance (BMA), we envision a Boulder where world-class mountain biking is accessible from your doorstep. A place where interconnected trails wind through scenic landscapes, offering opportunities for riders of all skill levels to explore, challenge themselves, and connect with nature.
This vision isn’t just a dream—it’s taking shape with every mile of trail built, every connection advocated for, and every rider we inspire. Together with supporters like you, we’re laying the foundation for a thriving mountain biking community.
Turning Vision Into Reality: 2026 Goals
Transforming Trails Across North Boulder
We are keeping the momentum going at Boulder Valley Ranch. In partnership with the City of Boulder, we will finish the remaining work at Hidden Valley. When complete, riders will enjoy 1.5 additional miles of fun, flowy singletrack. We will also help design the new Mahogany trail at Joder Ranch, adding another 1.5 mile loop that expands the North Boulder riding experience. As OSMP prepares for the North Foothills reroute, we are advocating to keep the techy hill on the southern end as an optional line that stays true to the character of the trail.
Advocating for Safe and Connected Riding
BMA continues to advocate for safe, multi-modal trail connections as part of the Citywide Strategic Plan 7C. This includes advocating for a connection between Shanahan Ridge and South Mesa/Doudy Draw. Better access means more people can reach trails without a car and enjoy natural surface connections between neighborhoods and trail systems.
Bold Opportunities at Betasso
Big changes are on the horizon at Betasso. Boulder County expects to close on the Fourmile property in 2026. This small but important parcel could unlock the long-awaited connection from Boulder Canyon Drive and Fourmile Canyon Drive into Betasso Preserve. We are advocating for an update to the 2009 Betasso Management Plan and exploring the potential for a new climbing-friendly multi-use connector paired with a downhill, bike-only return trail. Picture a modern loop that is open to bikes seven days a week with riding that feels like Fast Money at Maryland Mountain.
Connecting Boulder to Erie
The Boulder to Erie Regional Trail is officially moving into design. Boulder County has hired the design consultant team and they are already beginning survey work, including environmental and cultural assessments, to stay ahead of winter weather. The full design phase will run through 2026 and will include public meetings and opportunities for riders to get involved and share input. The County plans to update the project webpage before the end of the year, so stay tuned for more details as this important regional connection takes shape.
Supporting USFS Trail Systems
We remain committed to supporting the US Forest Service in West Magnolia, Brainard Lake, Peaceful Valley, and Lefthand. These areas offer some of the most beloved riding in the Front Range and we are working to ensure that upcoming planning efforts protect access, improve trail quality, and support the rider experience.
Fostering Community Through Riding
Our social rides program saw record participation this year, from expert-level adventures to beginner-friendly women’s rides.
Your donation directly funds trail building, maintenance, advocacy, and community programs that make Boulder a better place to ride.
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 volunteerism, social rides and events, advocacy, and trail building.
Boulder Mountainbike Alliance works towards three major goals: Build and Maintain Trails, Advocate for Trail Access & Create a Community of Mountain Bikers.
Boulder Mountainbike Alliance (BMA) is the voice for mountain bike trails in Boulder County. Originally established in 1991 as the Boulder Offroad Alliance (BOA), BMA was formed in response to the closure of nearly every trail in the Boulder area to mountain bikes. The organization represented cyclists who wanted the right to ride trails in Boulder again. In 2006, we changed our name to Boulder Mountainbike Alliance to more accurately describe our focus and mission.
Since then, we have worked nonstop to gain more trail access and have had some amazing victories. If you ride now, the landscape of trails that you use are largely a result of nearly two decades of attending public meetings, designing trails and, of course, volunteer trail building efforts. To learn about our last five year's successes visit Advocacy Success.
We design, build, and maintain trails in partnership with land management agencies in Boulder County. So far, we have completed more than 165 project days which contributed more than 27,500 hours of volunteer time. This is the equivalent of providing the land management agencies of Boulder County with a full time trail worker for more than fourteen years. The value of the contributed volunteer time alone exceeds $500,000. You can see the details at Trail Projects.
In 1996, BMA started the BMA Boulder Mountain Bike Patrol as a means of helping all users in the outdoor community to safely use our trails. Bike patrollers are not "the Man," but are volunteers who are prepared to help with bike problems, minor first aid, emergency response and, of course, provide great information about trails in the County. In 2017, our team of over 100 active patrollers spent about 18,000 hours and covered almost 11,000 miles while on patrol for Boulder City, County, and the U.S. Forest Service. You can learn more at Bike Patrol.
In 2009, BMA entered into a massive project with the City of Boulder to create one of the premier off-road urban bike parks in the country. Open since 2011, Valmont Bike Park now offers kids of all ages the chance to practice all forms of off-road biking from cross country mountain biking to jumping to cyclocross barriers right in town. In support of this effort we raised over $500,000 in public donations for the design and construction of the park.
