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 6K follow the scenic headwaters of the Rio Grande, 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 projects that improve water quality, wildlife habitat, recreation, and the overall condition of the Rio Grande headwaters. 

The Runoff Runoff event includes a marathon, half marathon, and 6K race run at 9,000 feet, and is usually held at the beginning of June. Following the races there is a fun celebration for the whole family, complete with live music, local beer, and food.

HWA is an equal opportunity service provider and employer and operates under a special use permit from the USDA Forest Service, Rio Grande National Forest.

After much thought and consideration Headwaters Alliance is canceling the 8th Annual RunOff RunOff Marathon, Half-Marathon and 6k Race due to the unprecedented COVID-19 pandemic. 

Maintaining the safety for the families, valued staff and potential visitors to our beloved mountain community is our top priority.  Per government and public health recommendations, we have implemented a remote work environment, are maintaining active social distancing practices and have canceled, or will reschedule events, in an effort to flatten the curve. We are committed to reducing unnecessary burden to the many vulnerable members within our community and the limited (but excellent) medical resources of our remote, rural county.

Past successful RunOff RunOff events stem from the enormous support of our local businesses.  Given the current economic stressors, it is our turn to give back. So while we are foregoing this year’s race, HWA will continue working with our many partners on the Comprehensive Willow Creek Watershed Planning Project, certification for Mineral County as an International Dark Sky Reserve and more. We welcome your ongoing support in these works!

We look forward to seeing you at the 2021 RunOff RunOff Races, here at the beautiful headwaters of the Rio Grande.  Be wise, stay safe, and may you and your loved ones enjoy health.

Please note, if you have already registered for the race, we will reach out to you directly to arrange for a refund. If you do not hear from us, please email coordinator@headwatersalliance.org.
