Register for the 2020 Seattle Marathon Summer 5K/10K

You will love this beautiful and iconic course on Lake Washington with views of Mt. Rainier. This is a dog-friendly event. For the Kids Fun Run, kids ages 5-14 are invited to run our 1-mile course (with shorter options for the little ones). Participants will receive a t-shirt, goody bag and participation award. Bring the whole family to Seward Park for these events.
