“The Big Backyard 5K is a great opportunity to have some fun in Marymoor Park, and it’s great having Kaiser Permanente as a presenting sponsor,” said King County Parks Director Kevin Brown.

A free kids’ dash featuring King County’s river safety mascot Marta the River Otter follows the fun run at 10 a.m., and then it’s time for post-event activities and awards ceremony at 10:15 a.m.

Now through March 31, for just $35, entrants will receive the popular BBY5K hoodie thanks to Harborstone Credit Union, an event t-shirt and bib-number, plus food, drinks, and more on race day. Youth registration is $20 for those 14 and under until June 8 and includes an event shirt.
