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.

We have events for children and adults of all athletic levels.
