Where your membership makes a difference

Trail Building and Maintenance by SDMB

  • Tucson Mountain Park

    SDMB has worked with Pima County to build the following single track and in some cases donated signs and maps:

    • Starr Pass: New Explorer re-route; Shemwell; new Starr Pass extension-- Rock Wren, Little Cat, Sarasota, Yetman re-route
    • Robles Pass
    • Enchanted Hills
    • Painted Hills

  • Sweetwater

    SDMB helped build and continues to maintain these popular trails.

  • Arizona Trail

    SDMB helped build 40 miles in Southern Arizona. 

  • Foothills Urban Assault Trail

    SDMB was instrumental in laying out this trail near Alvernon from Skyline to River Road.

  • Fantasy Island

    SDMB is working with the City of Tucson to assume maintenance, improvement and expansion of these trails.

  • 100 Acre Wood Bike Park

    SDMB provided the leadership for initiating and maintaining Southern Arizona's first urban MTB skills park.

  • Honeybee Canyon

    In partnership with Oro Valley and Pima County Parks & Recreation, SDMB helped build the Big Wash Trail to access the Honeybee trails and is spearheading efforts to preserve and protect more than 26 miles of premier single track that attracts riders from 27 countries and 45 states. SDMB also donated time and money to install a roll over gate at the state land boundary.

  • MacKenzie Ranch/Hohokam Trail

    SDMB helped build nearly 14 miles at Pima County's first XC race venue. Sponsors the annual MacKenzie Frenzy race in December.

  • 24 HOP Course

    SDMB participated in the design and construction of the original 24HOP course, and helped to maintain the quality of the trail for this annual event by hosting a trail work day, membership dinner, and group ride each year prior to the race. In addition, we are a beneficiary of the race by staffing the beer garden as a way to raise funds for more trail work projects.

  • Mt. Graham

    SDMB is in the process of improving and maintaining existing trails and planning new ones.

Why Your Membership in SDMB Matters

  • Fundraising and Grant Writing

    • SDMB is one of the few non-profit MTB organizations able to raise funds and write grants to assist with trail development. Such projects include the trails restoration on Mt. Graham, trails in Sierra Vista, the new Bike Ambassador program, Fantasy Island, and the 100-Acre Wood Bike Park. In addition, SDMB is one of the few non-profits in the valley that has secured AmeriCorps and American Conservation Experience (ACE) crews to help build and maintain trails--like McKenzie Ranch, Enchanted Hills and Starr Pass trails. Few other groups are able to engage with funders like SDMB.
    • Fundraising events like "Thirsty Thursdays" at local brew pubs, to support trails and trail building.

  • Events & Activities

    • We offer inclusive social rides to members for all abilities throughout the year, including the 8ish Days of Christmas, the Poker Ride and 24HOP Pre-Ride, the McKenzie Frenzy, among others
    • Volunteer opportunities including trail maintenance, event support, administrative duties and trail building days
    • Provide local riding information, tips, and guidance via our website, especially Featured trails and trail difficulty ratings.
    • SDMB offers skills clinics with certified MTB instructors 
    • Sponsors the annual "BrushtoberFest" to encourage members to brush out trails after an active monsoon season. 

  • Operating Costs

    Operating costs are essential to maintaining SDMB’s ability to build, maintain, and advocate for trails. Funding for insurance, equipment, communications, technology, and other basic organizational needs allows volunteers to safely and effectively carry out trail projects, coordinate with land managers and partners, support members, and advocate for the continued development and protection of local trails. Investing in these foundational costs ensures that SDMB can remain a sustainable and effective organization serving the mountain biking community.


  • Advocacy

    • Trail advocacy initiatives and advocates for political action on behalf of MTB'ers, including participating in the Network for Arizona Trails. SDMB was instrumental in getting the Arizona Legislature to unanimously pass a resolution (SCR1010) in 2022 expressing its support for the economic, social, health, and behavioral benefits of outdoor recreation. 
    • Works with all local land managers, public and private, to improve MTB access and relationships so that trails are protected and maintained. 
    • Is part of the steering committee for the Summit for Arizona Trails  to bring together trail advocates and users to unify our voice on behalf of outdoor recreation.
    • Is at the forefront advocating that Arizona join 22 other states by establishing an Office of Outdoor Recreation in order to better coordinate trails and recreation policies and funding across the entire state and to secure funding for building new and maintaining existing trails.

  • Outreach

    • Be Cool Campaign: SDMB conducts trailhead outreach events to educate trail users about good trail etiquette and fosters positive public relations with other trail users
    • Bike Ambassador program: This program is designed to improve public relations and to create a safe trail environment for everyone. Ambassadors actively try to engage with all types of trail users, and provide trail tips and information when requested. They also offer help, assist with basic bike repair in the field, provide information about how to protect the flora and fauna along the trails, and report problems related to the trailhead or the trails themselves
