Lake Union 10K Benefits Girls on the Run of Puget Sound. Girls on the Run of Puget Sound is a non-profit organization that inspires girls to be joyful, healthy and confident using a fun-experienced based curriculum which creatively integrates running.
*There is a good chance that the course will be impacted by the Fairview Bridge construction project. We are working with the City to find the best route and will post that info as soon as we confirm a course. Please note, we will not be refunded registrations based on a changed course.
Additional race information can be found at http://www.lakeunion10k.com/.
