The Color Me Rad 5k on Saturday, August 15, isn’t your ordinary family fun run. This untimed run/walk event is 3 miles, but it’s 3 miles filled with human graffiti. Begin the run squeaky-clean and be bombarded along the route with color gel, liquid and powder (all nontoxic, non-rash-inducing, washable, gluten-free colored corn starch) until you resemble a veritable rainbow. Kids 7 and younger can run for free or pay the $15 fee to get a color pack and running swag. Lake Sammamish State Park, $40-$60 adults. colormerad.com
