About the series...

In the summer of 2009, the first Magnuson run was held. Getting people to enjoy the outdoors via running and walking as well as participating in bettering our environment we thought was a worthy cause. So, after our first event we decided to turn the race into a series. Here we are today proudly presenting "a series for all seasons!" Join us for running and walking events for individuals, duos, and groups, based at beautiful Magnuson Park on the shores of Lake Washington in northeast Seattle. Rain or shine, wind or calm, we'll be here to help you meet your fitness goals and new friends at the same time!

The Magnuson Series is part of the organization Earth Runs whose mission is to encourage outdoor activities and enhancing our natural environment. The series goal is to provide low-cost fitness events for all ability levels and at the same time fundraising for tree plantings around the city. Over the years we have planted over 5,000 trees. We also partner with many other local nonprofits to help them fundraise at our events. 

We keep the same course each event so you can have a measurement for improvement. Our easy-to-follow 5k loop allows you to easily gauge where you are which helps with maintaining your pace.
