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, starting (for the marathon) and ending in the historic mountain town of Creede, Colorado. Organized by 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.

Course Info

The Runoff Runoff Marathon will begin in downtown Creede (exact location coming soon).  The course will go south through downtown and join the floodplain trail at the ballfields. The course continues down Airport Rd. and then turns right onto Deep Creek Rd. after crossing the Rio Grande. Runners continue on Deep Creek Rd. until HWY 149, at which point they turn left. After just one mile, runners take another left onto Middle Creek Rd. (FS 523). After 4 miles, runners stay right, remaining on Middle Creek Rd. (FS 523). Runners reach Soward Ranch and turn around. The race ends at the ballfields on the south end of Creede. The Runoff Runoff Half Marathon will start at Soward Ranch. The course follows the same trajectory as the Marathon, following Middle Creek Rd., spending one mile on Highway 149, and then turning right onto Deep Creek Rd. Runners will take a left on Airport Rd. at the end of Deep Creek Rd., and will follow it until the floodplain multi-use trail which brings them to the finish line at the ballfields. The Runoff Runoff 6K begins at the Creede Ballpark and follows the meandering Willow Creek floodplain trail out and back, finishing at the Ballpark. Runners, joggers, and walkers of all ages are welcome! Friendly dogs are welcome too, but they must be kept on a leash and owners must pick up after them.


Creede is located in southern Colorado in the heart of the San Juan Mountains. Highway 149 accesses Creede from the west and east.

Other Info

The purpose of the RunOff RunOff is to educate and engage with participants about three important interrelated issues: ​ 1. Legacy Mining Impacts and Water Quality 2. Water Quantity and the Connection with Downstream Communities and Ecosystems 3. Human Rights and Access to Water Worldwide -- the reason we have a 6k is because it is the average distance for women and girls in developing countries to access fresh water (USAID) We strive to preserve these glorious mountains and bubbling tributaries here at the headwaters of the Rio Grande. We take our upstream responsibility seriously, and deeply value your support in this work!
