Big River Adventure

Welcome to the 26th annual Big River Adventure!

Join us for a unique race experience where you can choose your adventure to run, swim, walk, or paddle your way through the scenic beauty of Mendocino County's Big River.

For the past 26 years, Cancer Resource Centers of Mendocino County has been bringing our community together for this special fundraising event. While the activities may change from year to year, our mission remains steadfast: to honor and remember those impacted by cancer, and to raise vital funds to support free services for individuals facing cancer in Mendocino County.

Starting at the Big River boat launch, participants will embark on a journey filled with stunning views and the shared goal of making a difference in the lives of others.

Don't miss out on this unforgettable adventure! Register now and be part of something truly meaningful.

To keep this family-friendly event affordable and accessible to our community, we will not be providing t-shirts this year.
