The Columbia River has provided this region's culture and economy for thousands of years. It is the largest river in the Pacific Northwest. The river forms in the Rocky Mountains of British Columbia, Canada and flows through Washington. This Big River irrigates more than 6,000,000 acres of agricultural land. Agriculture is huge part of our community and is possible because of this valuable water source.

The race course will have fun, themed aid-stations, cheer squads & music along the way. You run the miles, we bring the entertainment and support! We believe your achievements should be celebrated. Invite all the friends and family to come watch you cross the finish line! Chiawana Park as beautiful shade trees, a big grassy park and a gorgeous view of the river. After the race sit, relax, enjoy some post race treats and listen to a live band!!
