If you see groups of people running, walking or busing around Edmonds Saturday, many of them dressed in crazy costumes, there’s a good reason — and it’s for a good cause. The Great Edmonds Adventure — an “Amazing Race”-style competition — kicks off at noon at Harbor Square Athletic Club.

A benefit event for the Sno-King Youth Club, the Great Edmonds Adventure will involves teams of two working to solve clues in downtown Edmonds. “Each team will be responsible for solving clues to get to each task,” the event registration page notes, and “Each task must be completed and officially checked off to get the next clue.” There will be approximately 15 tasks to complete.

If you missed your chance to sign up for this fun event, there’s good news. You can show up the day of the race. Simply show up at Harbor Square Athletic Club at 10:30 a.m. and register in person. The price is the same — $40 per person (competitive level – two people) or $100 per team (family level – up to four people but one must be under the age of 10).  Check out www.thegreatedmondsadventure.com for more details.

Cost to register is $40 per person or $80 per team. Each team must have one member 18 years old or older, and the second member can be as young as 10. There is also a Family Team category for $100, which allows four members (one member of the family team must be at least 18).

For those of you still on the fence, here’s what to expect:

– Teams may only travel by foot or public transportation (including buses, trains and ferries).

– You are welcome to use “high-tech” items such as cell phones, laptops and GPS.

– You may ask anyone along the way for help and can also feel free to phone a friend.

– All teams are encouraged to wear a uniform and get creative – matching t-shirts, wigs, sunglasses, full costumes encouraged.
