Help build singletrack at Starr Pass in Tucson Mountain Park! 2016 was a a great year, with SDMB and our volunteers building 3.5 miles of new trail through 2,000+ volunteer hours and 3 weeks of paid trail crew (funded by you YOUR donations). We have 1.6 miles of fresh singletrack to go to complete this phase, which he hope to finish by the end of February.

No trail building experience is needed to volunteer with SDMB. SDMB provides all of the needed tools, along with lunch and post-work refreshments. All you need to bring is work gloves, closed-toe shoes, long pants, and whatever snacks and water you need.

Unless otherwise noted, all build days run from 8:00 AM - 12:30 PM and meet at the Richard Genser Trailhead a the S. end of Clearwell Rd. Please register via the appropriate link so we have enough crew leaders.
