Quilcene Oyster Races

About the Event

Come and run or walk our Half Marathon, 10K, and 5K races in peaceful Quilcene on the beautiful Olympic Peninsula!

The surroundings include woodlands, water, and mountains. All race proceeds benefit Quilcene-Brinnon Dollars for Scholars, which provides scholarships to high school seniors, recent graduates, and teachers to assist with their post-secondary/continuing education.

All Half Marathon, 10K and 5K events are USATF Certified and Sanctioned. Our Duo events are for participants paired with riders in jogging chairs/strollers (or for our easy 5K, even baby strollers and wagons!). All riders register for free!

The races begin and end at Worthington Park, site of the recently restored Victorian-era Worthington Mansion. Great scenery, awesome volunteers, and support for good causes make this a "can't-miss" event!

Registration includes:

A commemorative Finisher Medal
One serving of local oysters after the race
One local craft beer after the race (21 and over)
Free open house at Worthington Mansion
Lots of fun!
