Sunday, October 25, 2026Richland, WA5K – Marathon

The 43rd Annual Tri-Cities Marathon & Relay offers a scenic tour through the Tri-Cities region, featuring both full marathon and half marathon distances. The course is primarily flat, though runners should be prepared for some steep bridge ramps, including a final bridge crossing just two miles from the finish. Participants can enjoy a community-focused atmosphere with aid stations every two miles and a relay option for teams of up to four. The event honors the legacy of long-time champion Richard "Keith" Fuller while welcoming runners of all abilities. With a history dating back to 1980, this race provides a classic autumn running experience in the Pacific Northwest. Whether you are chasing a personal best or enjoying the team relay, the event promises a supportive environment with custom medals and awards for top finishers.
