Join us as we celebrate another exciting year of endurance, community, and achievement at the 43rd annual Tri-Cities Marathon! Runners of all levels are invited to take part in this long-standing tradition, bringing together athletes, families, and supporters from across the region for an unforgettable race day experience. 

New for 2026 

• The marathon course is returning to the previous route that includes the iconic Blue Bridge. Certification is currently pending.
• And that’s not all — we’re thrilled to introduce the Tri-Cities 5K. If you’ve always wanted to run in this celebrated race but weren’t quite ready for the longer course, now’s your moment! Costumes welcome
