This event is not chip timed — because the Wacky Dash is all about fun, not finish lines. We encourage you to take your time, enjoy the course, stop and connect with the local businesses and organizations along the way, and fully embrace the wacky. The only thing we’ll be measuring is how much fun you had!
We encourage the use of jogging strollers along the trails of this family-friendly 5K! And while we would absolutely enjoy a full parade of pups in wacky costumes, for the safety and comfort of all participants, we are asking that dogs sit this one out and not join runners or walkers on the course.
The Wacky Dash & Business Bash is a fundraiser for the Maple Valley–Black Diamond Chamber of Commerce, helping us continue our work to support, connect, and advocate for our local small business community. By participating, you are not only joining a fun community event — you are spending the morning connecting with local businesses, nonprofits, community organizations, and city leaders who help make our area such a special place to live, work, and gather. Thank you for supporting the Chamber, our small businesses, and this amazing community.
