13 mile course:
From the south beach of Seward Park, north along the east shore of the Seward Park Peninsula, crossing the shipping channel from the northeast corner of the park to the Mercer Island Shoreline and the east high-rise of the I-90 floating bridge and then around the island in a clock-wise direction finishing back at south beach of Seward Park. Organizers may make a race-day decision to reverse the course, depending on prevailing winds. It’s always better to finish with a tail wind instead of a headwind!

3-1/2 mile course:
From the south beach of Seward Park, north along the east shore of the Seward Park Peninsula, around a buoy at the northwest corner of the peninsula and returning to the onshore finish-line at the south beach.

Kids Race:
Approximately 1/2 mile buoyed course in front of the South Beach

Team Relay Race:
