Eighth-annual fun and family-oriented event is presented by Kaiser Permanente,   and helps supports King County Parks – Your Big Backyard

Join with friends, family and fellow outdoors enthusiasts in a fun event that supports King County Parks – the Big Backyard 5K presented by Kaiser Permanente, Sunday, June 11 at King County’s Marymoor Park. Sign up by March 31 to receive a special event hoodie at a reduced rate.

This family-friendly event starts at 9 a.m., and takes participants through beautiful Marymoor Park at the northern end of Lake Sammamish. The course follows the Marymoor Connector Trail and a portion of the East Lake Sammamish Trail. The run is chip timed, and strollers and leashed dogs are welcomed.

“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.

Registration for the 2017 run is easy – sign up online at and learn about the various registration packages between now and race day. The Big Backyard 5K promotes fitness and community involvement, and has raised more than $250,000 for King County Parks in the past seven years.

Looking for more incentive to sign up? How about cash! Break the course record (15:32 for men, 19:36 for women), and you’ll win $100.
Funds help leverage King County taxpayers’ investment in parks, trails  and open space by keeping these features open and safe for all to enjoy.
