ABOUT
Founded in 2010, the Big Backyard 5K, also known as the BBY5K, is a community run/walk
showcasing King County Parks.
Proceeds from the BBY5K benefit King County Parks, supporting maintenance and operations of facilities and recreational resources. Over our 12 years, more than 12,000 runners and walkers have gathered to raise over $75,000 for King County Parks. Thank You!
This year’s event is presented by Harborstone Credit Union and celebrates our ability to gather together again with a simple approach to fun and fitness.
Please join us on Sunday, June 5 to celebrate in Your Big Backyard.

LIVE 5K RUN-WALK
This year’s BBY5K will have a mass start, broken into waves based on your pace, and to keep things less crowded on the trail. Waves start at 8:00am with TEAMS, followed by a run/jog wave, and the “Enjoy your Park” pace.
As usual, your 4-legged running companion may join you. Please keep your leashes short, and remember to pick up after your pet.
VIRTUAL 5K RUN-WALK
Can't make it to the event? Run your 5K virtually from anywhere! You will be emailed a link to report your time when you sign up. Submit your results to us anytime between June 6 to 20. Apps such as Strava, Garmin, MapMyRun, etc. are appreciated, but we will also take your word for it in support of King County Parks. Packets will be mailed to Virtual participants.
TEAMS
Sign up with your friends and running buddies! We will take the combined time of your Fastest 5 finishers to calculate Team Awards. Sign-up as many team members as you want and improve your odds of winning. Ask your Team Captain to enter your Team Name when he/she registers. Individual members will select your Team Name from the Pull-Down Menu in the Team Registration field. This is a LIVE event (only), and we look forward to watching the competition.
