Register on Webscorer

Online pre-registration is open until September 3 at 11:59.


Dash Point State Park is a 398-acre camping park in the Pacific Northwest with 3,300 feet of saltwater shoreline on Puget Sound. The beach provides unobstructed views of the Sound and lots of opportunities to observe wildlife such as coyotes, foxes, ducks, eagles, and of course, plenty of marine animals. The upper trails of the park have beautiful views of Maury and Vashon Islands, the Olympic Mountains, and spectacular sunsets.



The Start/Finish area has many stations for picnic and BBQ, and it is right by a nice long stretch of sandy beach. This is a great location to bring out the whole family for a fun day by the water. The trails at this park are non-technical, cushy and well maintained, and it is an excellent place to use your minimalist shoes if you so desire. We took some photos of the beach, the picnic area and the trails a few years ago and you can find the shots here.


We offer 10K and Half-Marathon (13.1 miles) distances. There will be plenty of aid stations and the courses are well marked with signs at intersections. As always, there will be a good selection of grub at the Finish to fuel you up.


Because Dash Point is a WA State Park, a Discover Pass is needed. Please see the "Directions" tab below for more information.

Course Map

Dash Point State Park is a 398-acre camping park with 3,301 feet of saltwater shoreline on Puget Sound. The beach provides unobstructed views of the Sound and excellent opportunities for sea-life study. The park features a beach, a variety of water activities and great views of Puget Sound.

Read about how we keep the races green here.


We are dedicated to the responsible enjoyment and active stewardship of the outdoors, and we encourage you to "leave no trace behind" by taking all trash with you. The park rangers always appreciate it when racers follow the marked course and keep the trails clean, and they are much more likely to grant permission for us to put on races at the same location if the trails are kept in good condition.


The trails will be open to other users during the event such as hikers and mountain bikers. Please be courteous, you will unlikely encounter more than a few. Please let other participants pass you if they want to get by. It is a passing runner's job to tell the person in front that they wish to pass.


For refunds/cancellations please see our policy.


Photos and results from trail runs previously held can be found on the photos page and results page respectively.
