Still time to take part in 5th-annual King County Parks’ Big Backyard 5K, June 1 at Marymoor Park

Presented by Group Health, this fun family event benefits King County Parks

It’s almost time to join with friends, family and fellow outdoors enthusiasts in a fun event that supports KingBBY5K_dogs County Parks – the Big Backyard 5K presented by Group Health, Sunday, June 1 at Marymoor Park.

The Big Backyard 5K 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. Strollers and leashed dogs are welcome.

A free kids’ dash sponsored by Whole Foods and featuring King County’s environmental mascot, Bert the Salmon, follows the fun run at 10 a.m., and then it’s time for the awards ceremony at 10:15 a.m.

Register online at prior to race day for $40 and you’ll get an event t-shirt, plus food, drinks, timing chip and more on race day. Day-of-race registration is $40, and includes all of the swag mentioned earlier, except the t-shirt, which is only available while supplies last.

Funds raised by the 5K help leverage King County taxpayers’ investment in parks, trails and open space by keeping these features open and safe for all to enjoy.

Looking for more incentive to sign up? How about cash? Break the course record (16:18 for men, 20:15 for women), and you’ll win $100.

The Big Backyard 5K promotes fitness and community involvement, and has raised more than $125,000 for King County Parks.
