About

The Big River Adventure in Mendocino, California, offers a 10K run (6.2 miles), a 5K run and a 5K fun walk (3.1 miles) on May 29, 2027, along with a swim. It is organized by the Cancer Resource Centers of Mendocino County. Participants can choose to run, swim, walk or paddle in the scenic Big River area, starting from the boat ramp.

The runs and the Big River Swim start at 8:30 a.m. and the fun walk at 8:45 a.m. The event honors those affected by cancer and raises money for free cancer support services in the county. Several age categories are available, with reduced fees for younger participants. The event is family-friendly, but no T-shirts are provided in order to keep it affordable, and paddlers must bring their own boat.
