DoD exists to preserve and enhance mountain bike access through trail stewardship, advocacy, outreach, social rides, and responsible trail use.
Members and donors support real trail work, local partnerships, and close-to-home riding opportunities for all ages and abilities.
Start with Thurston Hills, Carpenter Bypass, Oakridge, Ridgeline shared-use routes, and North Shore. Conditions matter, especially in winter.
Come to a Happy Ride, Taco Tuesday at Thurston, a trail work day, or a DoD event. The newsletter is the easiest way to see what is coming up. Or go the Eugene Mountain Bike facebook group and introduce yourself. There's all different types of rides, those who want downhill and those who carefully measure the weight of their bike. Great advice there about tire pressure and type too.
Yes. Every volunteer starts somewhere. Experienced trail stewards can teach brushing, raking, tread repair, drainage, hauling, and tool safety.
Membership funds trail building, maintenance, advocacy, insurance, tools, and events. It also shows land managers that mountain bikers are organized.
DoD is registered as a not-for-profit organization under IRS section 501(c)(3). Donations may be tax-deductible; check your own tax situation for details.
Because the club loves dirt, singletrack, and the good work of keeping trails open, sustainable, and fun.
We're in Eugene, so there's a lot of biking groups here. GEARS does low pressure group bike rides on mostly asphalt. There's a Eugene VELO. Nearby, Team Dirt does amazing work in Benton County (Alsea Falls, Mary's Peak, and the Mac Dunn), Oakridge Trail Alliance is killing it in Oakridge, Centra Oregon Trail Alliance supports an amazing network in Central Oregon, BRMBA created a legendary system at Black Rock, and North West Trail Alliance is doing great work in the greater Portland Area. Out on the coast, NEWTS, Wild Coast, and TORTA keep the local coast trails going strong. We partner with these other organizations as scheduling and availability allows. We all have the same mission. More bikes. More trails. Unlike Washington where Evergreen basically runs stuff for the whole state, in Oregon the bike clubs and trail organizations or more locally created and driven.
Tools require maintenance, occasional replacing, and volunteers are more motivated when they have some snacks to keep them going. There's of course minor administrative costs to running a website and paying for basic liability insurance for the club. We occasionally hire outside contractors to lead professional builds or rebuilds of trails, often partnering with volunteers for others parts of the build. Check out some trails at Carpenter Bypass like Hit Parade, Y2k, or Cedar Shark at Thurston Hills to highlight the quality work that can be done with local pro builders we've partnered with. But rest assured, no one on the board takes a salary, our pass through rate as a charity is quite high (91 percent based upon the most recent calendar year).
We love kids, and mountain-biking brings out the inner kid in all of us. You are welcome to bring kids with biking experience to some of our group rides like Taco Tuesday, All-Comers Meet, or Take-A-Kid-MTBing. Eugene Composite is a local cross country mountain biking team. They focus on racing, developing core skills, and teambuilding. Any kid going into middle school (summer they go into 6th grade) through high school seniors can join. See Eugene Composite's website for more details: https://www.eugenecomposite.org/

Trailforks mapDoD is a volunteer-powered nonprofit, so cash spending only tells part of the story. Even so, recent P&L data shows a high share of spending going to trail building and programs.

Data: DoD cash-basis P&L, Jan-Apr 2026. 2020-2025 broader program-service ratio: 83%. Figures are internal estimates unless audited financials are provided.

From Oakridge and Carpenter Bypass to Thurston Hills, Ridgeline conversations, and future Eugene/Springfield trail systems, DoD’s role is to keep mountain biking visible, responsible, and organized.
