Up in the San Juan Mountains of Southern Colorado, the Rio Grande begins it's 1,800 mile journey to the Gulf of Mexico. The Runoff Runoff marathon, half marathon, and 6.6K follow the scenic headwaters of the Rio Grande, starting and ending in the historic mountain town of Creede, Colorado. Organized by the Headwaters Alliance (formerly the Willow Creek Reclamation Committee), this event raises funds to support river restoration and stewardship projects that improve water quality, wildlife habitat, recreation, quality of life, and the overall condition of the Rio Grande headwaters.
