The Tri-Cities Marathon is back! The 41st edition of this classic race will be held Sunday October 26th.

Join us at the Riverfront Hotel in Richland to run a half or a full marathon. Don't feel like going that far? You can also form a relay team of up to four and cover the 26.2 miles together.

The Half Marathon course will be the same as before, an out and back through Richland and Pasco, mostly on the paved trails, 6.5 miles each way. This is a USATF Certified Course and is also record eligible.

The Marathon course will be changed this year, as the Blue Bridge construction won't be finished until January 2025. The new course is not finalized yet, but will include a full loop of the river trail with an out and back section to make 26.2 miles. The start and finish locations will remain the same as before. We plan to have the Marathon course certified this year, so you can qualify for Boston, Chicago, etc., or to simply make your results official.
