Race Benefit: Most of the trails in the Corvallis area are maintained by volunteers from groups like the Mary’s River Chapter of the Sierra Club, the Greenbelt, the Boy Scouts and many others.??Proceeds of this event benefit the Greenbelt Land Trust Trail Fund. This fund helps purchase raw materials and equipment used for trail construction and maintenance by the volunteers who keep our trails safe and passable for users. Over $20,000 has been raised in the last five years. Proceeds have been donated for gravel and supplies to support the City/County/CSC Youth Trail Crew that has worked on our entire trail system.
