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!
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!
