Snohomish Running Company and Oiselle are excited to bring Seattle the Tenacious Ten 10K & 10 Mile running race around South Lake Union. We invite you to join us, either to run, to cheer at one of the themed cheer stations, or to participate as a race-day booth sponsor at the finish line. We encourage local businesses to offer whatever they would like to sell, capture marketing information, provide services, or create brand recognition.

To register for the run, visit, or for more information about having a booth at the finish line or for corporate and community group discount registration programs, contact [email protected].
