## Description

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 Spooktacular 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
