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.
