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.



The popularity of Epic Rides‘ signature event is increasing faster than mountain bike wheel sizes! And SDMB is incredibly excited to be a part of this fantastic event. We invite you to stop by SDMB-Town (on the right just before you enter 24-Town proper) and say “Hi!” Sample some great Catalina Brewing Company beer while you’re there.

Please visit our official SDMB booth in “town” and take a look at the new SDMB shirts, socks and other schwag, and don’t forget to pick up a complimentary cho-comb. What could be better than that? How about some amazing Sierra Nevada beer? Proceeds from all the SDMB Beer Garden sales goes directly into maintaining Tucson’s trails through our Trail Love program. Beer Garden hours are: 2-8 Fri, 11-9 Sat, 10-2 Sun.

See you there!

Trail Love – Sweetwater – Feb 22


Come out for the February SDMB Trail Love Corps Day, on February 22nd. We will continue to build singletrack at Sweetwater, this time to complete the last mile of a loop in the new parcel. As there is limited parking at the work site, we will be carpooling.

Meet at the corner of Silverbell and Sweetwater (near the PACC) at 8:00 AM. Look for the SDMB flag!

Bring work gloves, water, and snacks. We will work until noon, then lunch from Beyond Bread and beverages will be provided by SDMB.

Please RSVP to trailsteward@sdmb.org so we can make sure to have a lunch for you.

If the weather is bad, check Facebook or TucsonMTB.com for updates.

24 Hours in the Old Pueblo – Sierra Nevada Beer Garden


SDMB has an exciting opportunity at the 24 Hours in the Old Pueblo this year, running from Friday, February 13 through Sunday, February 15. We will be running the Sierra Nevada Beer Garden in 24 Hour Town!

This will raise significant funds for trail development in Tucson, but we need your volunteer help. The beer garden will be open on Friday from 2:00 PM – 8:00 PM, on Saturday from 11:00 AM – 9:00 PM, and on Sunday from 10:00 AM – 2:00 PM. Shifts are only 2 hours, and are guaranteed to be a good time. All proceeds go directly to support upcoming trail projects in the Tucson area, including new singletrack in Tucson Mountain Park and the 100-Acre Wood Bike Park.

As a bonus for anyone who volunteers, folks who come out for a 2-hour shift will get a free SDMB pint glass, and anyone who comes out for 2 or more 2-hour shifts will get a pint glass and a pair of SDMB socks. Pretty cool, huh?

To sign up for shifts, go to the Doodle link below. Make sure to let your friends and family members who will be at the race know, and forward the link to anyone you think might like to volunteer. Email Trailsteward@sdmb.org with any questions.

Even if you can’t volunteer, come by, have a pint, and drink beer for trails! All proceeds go to SDMB to help make your trails better.
