Local runners and walkers joined in an April 22 nationwide memorial to support the city of Boston and victims of the marathon bombings.

The “Boston Strong Sammamish” run and walk drew nearly 100 participants from Redmond, Sammamish and Issaquah to Plateau Runner, the local speciality running store that sponsored the event. Wearing green headbands and armbands, participants ran or walked a 3-mile course in solidarity.

“We had families pushing baby strollers, kids from local middle and high schools, even some Boston Marathon racers,” say Plateau Runner store owner Elizabeth Steen. “It was heartwarming to see the community turn out to support Boston.”

The grassroots “Boston Strong” movement organized similar runs throughout the country on April 22. Steen first heard about the event from a customer, who got her in touch with the website www.pavementrunner.com. Along with posting on that website, Steen created a Facebook page for “Boston Strong Sammamish” and emailed the store’s customers about the run.

“I posted on Facebook on a Thursday and was amazed at how fast word spread about the run,” says Steen. “I think people wanted to do something to show support for the victims and the entire city of Boston, and a community event like this appealed to them. We were so happy to be a part of this.”
