The Disciples of Dirt Mountain Bike Club (DOD) boasts members from all over the Pacific Northwest and beyond, but we focus our efforts within Oregon’s Southern Willamette Valley, where the club was founded and the majority of our membership live and ride. Club members share a high level of passion for mountain biking and the DOD is well known within the cycling world for being stewards of our local trails and champions for improved trail access for cyclists.




DOD is always in need of volunteers for trail work, events, communication, and more. Please sign up HERE, and tell us about your skills and interests.

Thurston Trails

Thurston Trails

Trail contractors are starting work at Thurston Hills Natural Area once more, beginning with a gravel multi-use hiker trail from Quartz Park up into the hills. The trails won’t be ready for use until later this fall, and we’ll have more information as we prepare to open them up. What this means for you: Note that while vehicles aren’t normally permitted on the haul road, there will be trucks scheduled to deliver gravel to the work site over the next few weeks. Be observant and stay tuned!

Trail Volunteers

Trail Volunteers

Creative Trail Designs is back at Whypass for the next few weeks. We plan to rebuild a few turns at the south end of Alpha then continue on Your Sister with the machine build. Current plan is two volunteers needed/day/shift starting 9/30 through 10/6. If you are available to assist, please email [email protected] and provide what days you can help, including your preference for morning or afternoon shift. I will do my best to schedule the volunteer support. The build crew has requested all volunteers be vaxxed. Thanks.

Thurston Hills

New hiking and mountain biking trails are on the way! Willamalane and Oregon Woods Inc. have started work on new trails on the southwest side of Thurston Hills Natural Area. Expect vehicles traveling intermittently on Camas Crest Trail as we get the job done. Other trails won’t be impacted. Keep tabs on progress at
