Seward Park
The Seafair Triathlon is returning home to Seward Park for 2025! We are SO excited to host over 1,400 triathletes at Seward Park this year. Seattle's ONLY triathlon will once again take over the shores of Lake Washington this summer, and Seward Park is the perfect backdrop for this flat, fast, and picturesque triathlon course in the shadows of downtown Seattle.
Available volunteer roles for the triathlon are limited to approved emergency management and medical (EMG) team members, who must be logged in to view shifts. Contact signup@emgwa.org for more information.
There are no shifts available at this time.
