ABOUT

Founded in 2010, the Big Backyard 5K, also known as the BBY5K, is a community-run/walk at King County’s Marymoor Park. Proceeds from the BBY5K benefit King County Parks and brings the organization financial support for maintenance and
operations of Your Big Backyard. With your help over the years, we have raised more than $250,000 for King County Parks!

After our 10th year, we are continuing with a 10K course option! Pick your distance
and find your pace. Run/Walk 5K or Run 10K!

The BBY5K is family-friendly. Strollers and leashed dogs are always welcome. Don't forget to stick around after your run/walk for a FREE Kids Dash and the fabulous, interactive Post Race Celebration, presented by Pape Machinery featuring refreshing drinks, tasty food, great tunes, and fun prize giveaways.

COVID-19 STATEMENT

In this time of great uncertainty with COVID-19 hanging over our head, limiting our interaction, and restricting our travel, the Big Backyard 5K has made a decision to postpone our event originally scheduled for Sunday June 7.

We want you to stay healthy, keep up your running and walking. Get outdoors, and enjoy our trails! Of course we want you to maintain your social distance, and practice appropriate behavior based on the recommendations of King County Public Health and our government officials.

For those of you who have already signed up, your registration will now be transferred into to the “live” 5K/10K, which we hope can take place this fall. Additionally, you will automatically be included in our “Virtual” run. We are excited to provide you this extra opportunity to post an intermediate time. We will share details soon, and have some fun with that when we come out from under the virus. New participants may register for just the “Virtual” run, as well as our “Live” 5K and 10K today.

We hope to announce a new date soon, but must wait for restrictions to lift, and virus cases to subside before confirming a schedule. We will continue to work with King County Parks, and follow the guidance of public health authorities to create a safe and healthy event for you.

We look forward to getting back to what we remember is normal, and run together to support King County Parks.

Please refer to the King County Parks: Coronavirus Update for more information.

EVENTS

We will have “I ran virtually for King County Parks” T-shirts for you to pick up at Super Jock ‘n Jill when we can freely move about the community, or, at Packet Pickup on BBY Weekend.

You can sign up now for "just" the virtual run, and sign up later for the LIVE 5K/10K. Just remember that prices go up as we get closer to event day.

5K RUN-WALK

Go at your pace on a lap around Marymoor Park. It’s 3.1 miles of exploring one of the most versatile recreation facilities in the region.

10K RUN

In the interest of time and safety, we request that 10K participants race-run-jog the10K course. We have adjusted the route to reduce cross-traffic experienced during last year’s race. You’ll love the lack of hills!

TEAMS!

Team up with your friends and running buddies! We take the combined time of your Fastest 5 finishers to calculate Team Awards. Sign-up as many as you want on your team to improve your odds of winning. We will announce the Fastest Team in the 5K at 10 a.m., and the Fastest Team
for the 10K at 10:30 a.m. Team Captains must contact us in advance to set up your Team Name on the registration site.

Team up with your dog! Is Fido fast? We will award the first dog owner and their dog across the line in both the 5K and 10K!

KIDS DASH!

FREE for kids age 10 and under. Sign-up in-person ONLY on Race Day at the registration tent. Parents must sign a waiver in order for kid to participate.

Follow King County's Marta the River Otter to the finish line in this very popular and fun ¼-mile loop! Parents may run with their kids. Kids will also receive a Bib Number and Finisher's Ribbon.
