Lake Union 10K

When: August 15, 2021
Where: Seattle, WA
Race type(s): 10K

We are heartbroken to announce that due to the concern surrounding COVID-19, Lake Union 10K has been canceled. While events of our size may be permitted by August, we don't feel comfortable proceeding with the race given the risks.

We are sad for our runners and walkers, for our nonprofit beneficiary, Girls on the Run, for our sponsors, vendors and the community. We would not be able to provide you with the best and most fun experience with serving of Portage Bay Cafe breakfast, and running as a group given the public health code guidelines. We feel like this is the safest choice given our current situation. We will be together at the start line soon.

If you have already registered please check your email for your options.

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.
