Help BMA Level Up with our Invest once, Build for Years Campaign
At Boulder Mountainbike Alliance, we believe great mountain biking should start close to home. Connected trails, smart design, and riding that is actually fun take more than good ideas. They take the right tools.
This month, we are raising money to purchase a mini-excavator to support trail construction and major maintenance projects across Boulder County.
Why a Mini-Excavator
If you’ve ridden a trail in Boulder County that felt just right - sustainable, flowing, built to last - there’s a good chance Mike Rutter had something to do with it.
As BMA’s Trails Program Director, Rutter is out there in all conditions, often with nothing more than basic tools, skill, and determination building and maintaining the trails our entire community loves.
In 2025 alone, Rutter led efforts that:
What This Unlocks in 2026
Rutter has accomplished much of this with simple tools, or by renting equipment when budgets allowed.
We can do better for Rutter. And we can do better for our trails.
BMA has launched a capital campaign to purchase a mini excavator, a tool that will dramatically increase Rutter’s efficiency, allowing him to:
This is about giving Rutter the ability to do more and making every donated dollar move more dirt.
This is your opportunity to give him the tool he needs to do more in 2026 and beyond.
Invest Once. Build for Years.
In less than two years of rental costs, we could own our own mini-excavator. And instead of using it for just a few months, we could put it to work all season long.
More capacity. More impact. More fun on trails.
Help Us Name the Machine
When you donate, you can suggest a name for BMA’s future mini-excavator. Once we hit our goal, we will share the top suggestions and let the community vote.
This machine will shape trails for years to come. It deserves a great name.
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.
