Join us on a fully supported bicycle odyssey through the scenic back roads of beautiful Columbia County in NW Oregon.  The ride will start and finish in Clatskanie Oregon.  Registration and packet pickup begin at 6 AM and the course opens at 6:30 AM.  The ride will be equipped with aid stations spaced approximately 20 miles apart.  Aid stations will have a restroom, snacks and water.  There will also be a couple of roving SAG vehicles as well as a handful of official ride support personnel out on the course to help.   The Columbia Century Challenge will once again showcase both a Century Plus and a Metric Century Plus.  Course information will be finalized soon.
