Thank you all for your continued support of this event.
All net proceeds from this event go directly to the Sierra Buttes Trail Stewardship trail maintenance program. In addition to entry fees, SBTS will receive all proceeds from prize drawings, silent auctions and beer donations. In all, it should amount to $25,000 or more, depending on racer turnout and the amount of beer that gets consumed. That's $25k going directly into the maintenance and restoration of the Downieville Trail System.
Money well spent in our minds, and you get to have a damn good time in the process.
