Take out that magnifying glass, get your notepad ready and hone in on your sleuthing skills for the fourth annual Gumshoe 5k Walk to support the Greenwood Senior Center.

Not your average three mile walk, the Gumshoe 5k requires walkers to solve simple clues as they make their way through the Phinney and Greenwood neighborhoods.

This year gumshoes can participate in the walk from August 6 to 17.

Started by Mike Veitenhans four years ago, it was an idea of his to help raise money for the senior center.

“The first year we had about 75 walkers and last year there was about 250 walkers,” said Judy Mirante, Greenwood Senior Center board member.

This year the focus is on getting Phinney/Greenwood businesses involved.

“One of the things that is different about this walk is that it involves a lot of the businesses in the community,” Mirante said. “This year for the MiniGumshoe contest, stores have agreed to place a Gumshoe sticker around the store and contestants are to identify the words associated with each sticker.”

In doing so contestants are entered to win a number of prizes and certificates from participating local businesses.

“Last year was the first year for the Minigumshoe contest,” MIrante said. “We had about 10 to 11 businesses last year, this year stores realize what it’s all about and are quite interested in participating.”

A similar contest are for participating restaurants called the Eatsy Street Game. With each entry form there contains nine photographic clues identifying restaurants between 59th and 87th streets.

Contestants who correctly identify all nine restaurants are automatically entered in the separate Eatsy Street Game prize drawing for gift certificates to each restaurant when they turn in their Gumshoe entry form.

Last year’s walk earned about $4,500, Mirante said she would love more walkers this year and would like to at least match last years number.

“We know the economy isn’t so great this year but this is really a fun neighborhood activity and it’s fun to do it in a group and fun for kids,” she said.

Funds raised help to pay for the many programs that are offered at the center.

“I love this event, it is one of the most creative and community oriented events and we are just honored to have wonderful volunteers like Mike Veitenhans who put his heart and soul in creating an incredibly fun, challenging, business and community oriented event,” Cecily Kaplan, director of Greenwood Senior Center said.
