Thanks for visiting the Sonoran Desert Mountain Bicyclists! We are an all-volunteer 501c3 non-profit organization devoted to the promotion of mountain biking, and view the sport as a vehicle to promote low impact outdoor recreation, conservation, and opportunities that are environmentally and socially responsible. We hope that you will use this website as your Tucson mountain biking resource for finding events and trails to ride, as well as to stay up-to-date and help our trail advocacy efforts.

Social Ride – Starr Pass

Join us on Saturday, June 13th (7:00am) at the main Genser Trailhead for a social ride at Starr Pass

We have been working hard with Pima County to lay out more than five miles of new singletrack that we hope to start building in the fall. On the ride we will show folks some of the proposed corridor and answer questions about proposed trail closures in the future.

We will ride the “regular loop” including the Yetman reroute, with more miles if folks are interested. Mellow pace, no one gets dropped.

Email trailsteward@sdmb.org or go to the Facebook event page with questions or to let us know you’re coming out.

SDMB Wins $10,000 Grant

We are absolutely thrilled to announce that SDMB has been awarded a $10,000 grant from REI to support the construction of 5.5 miles of singletrack in Tucson Mountain Park.

“We are excited to provide your organization with funding, but more importantly we are committed to strengthening our partnership. Working together, we hope to build greater awareness of your efforts to care for and increase access to the outdoor recreation places where our members and customers play, as well as REI’s investment in your organization.”


– REI Representative

Thank you REI! We feel the same way!  Please keep an eye out for future trail building days so you can help us put these fantastic grant funds to good use!

SDMB/SOLO Wilderness First Aid Course

When:  Saturday & Sunday, May 30-31, 8:00 AM – 5:00 PM

Where: Pima County NRPR Building – 3500 W. River Rd, Tucson, AZ 85741

The details are finalized and registration is live for the SDMB/SOLO Wilderness First Aid course, Saturday and Sunday May 30 and 31!

As mountain bikers, trail builders, hikers, and all-around outdoor enthusiasts we spend lots of time in the backcountry and in risky situations.  Ordinary first-aid training doesn’t cover the types of medical emergencies that can occur in the backcountry, and adequate training and preparation can make the difference between a near-miss and a helivac, or worse…

The Wilderness First Aid course will be taught by SOLO, the oldest school of wilderness medicine in the U.S. Those who complete it will receive a 2-year WFA certification. Find more information about SOLO and the course curriculum.

Wilderness medicine courses are highly experiential, and combine classroom learning with hands-on practice and simulations.  This course will be taught by James Corbin of the Central Arizona Mountain Rescue Association (CAMBA).  In addition to providing highly useful skills and information, they are just plain fun!


Registration is only $155, and the first 10 SDMB members who register will get a $25 gift card to Tucson Endurance Performance Center.  As an added bonus, SDMB will provide lunch for both days.

There are 2 steps to registration:

  1. Register Through Paypal. 
  2. Email trailsteward@sdmb.org to confirm your payment and attendance.  Be sure to say if you’re an SDMB member so we can save your Tucson Endurance Performance Center gift card!

April Trail Love: Bug Springs!

Bug Springs Trail Day

Join SDMB for our April Trail Love Corps day, Saturday April 18. In our continuing stewardship of Bug Spring trail, we will be working on the middle section between the creek valley and the hoodoos. We will be doing erosion control, improving corners, and improving flow along the entire trail corridor. The upper and lower parts of Bugs are in great shape; let’s get the middle part in equally great shape!

We will be shuttling up to the top of Bugs and working our way down. We will likely be out past lunch, so bring a lunch and/or snacks for the day. SDMB will bring beverages for the post-work festivities.

Meet at Le Buzz at 7:30 AM, and plan on working into the afternoon. We will bring the tools, you bring work gloves, water, lunch/snacks, and good footwear/clothing for the day.

RSVP on the Facebook Event or email trailsteward@sdmb.org.
