It’s a triple-header!

  • Come race the Dog Bones event at Edmonds Community College in the afternoon!
  • Celebrate Founders’ Day and the club’s annual meeting afterward!
  • Once the sun goes down, avoid vampires at our Vampire-O at adjacent Lynnwood Golf Course!

The Choose Your Adventure series is designed to be extra fun, social, and friendly for beginners, yet interesting for seasoned veterans.

At Choose Your Adventure events, everyone gets the same map with checkpoints marked all over it. Then, after a mass start, you can find as many checkpoints as you want! Just be sure to mind the time, since there’s also a time limit. Return to the finish on-time, or lose precious points for every minute you’re late. (Wear a watch!)

Thanks to the excitement-inducing time limit, everyone finishes around the same time, making post-event socializing a core feature of Choose Your Adventure events.

Come join the fun!

Is this your first event or do you want to improve your skills? Meet us from 1:00pm – 2:00pm for up to an hour of free skills instruction!


Like many Choose Your Adventure events, there are 24 checkpoints on campus, split in half so that 12 are on Map 1 and 12 are on Map 2. You have 75 minutes, with a mass start at 2:15pm and the time limit running out at 3:30pm.

But here’s the Dog Bones twist!

The 12 checkpoints on each map are actually 6 pairs of 2 checkpoints (each pair resembles the shape of a dog bone). Once you visit 1 of the 2 checkpoints of a “bone”, you then must go next to its pair checkpoint, completing the “bone”. After completing a bone, you may go visit any other bone. You can visit the 6 bones in whatever order that you like. You can start each bone from either checkpoint, as long as you go to the other one next.

Once you complete the 6 bones (12 checkpoints total) from the first map, come back to the start/finish area and we’ll give you another 6 bones to visit!

How does the scoring work?

All 24 checkpoints are worth the same amount: 1 point per checkpoint. The maximum score is 24 points. The first person or team returning with 24 points wins!

There’s a time limit of 75 minutes, and for every minute late, there’s a 1 point penalty.

Note for the map exchange: If you skipped any checkpoints from the first map, you cannot go back and get them once you take your second map. (This rule is to prevent an unfair advantage by collecting both sets of checkpoints during one loop.)

The Dog Bones event will stay only on the Edmonds Community College campus (and the evening’s Vampire-O will stay only on Lynnwood Golf Course.

There is a very large construction project on the north part of campus, which has been accurately mapped.

To visit all 24 checkpoints in the dog bones format, the as-the-crow-flies distance is approximately 5 kilometers.

What’s an e-punch?

An e-punch records your race. At each control, you’ll dip the e-punch into an electronic box, which will beep and flash as confirmation. After you finish, you’ll download the e-punch at the download tent and get a receipt that show which controls you visited and how long you took between each; these are your “splits.”

Part of the fun of orienteering is comparing your splits with people who completed the same course, and discussing the routes you took!

Day-of-event registration is available by cash or check, made payable to Cascade Orienteering Club

Navigational Challenge: 2

Physical Challenge: 1


Return to the Finish
All participants MUST return to the finish and download their e-punch or turn in their punch card.

Even if you have not finished your course, you must still return to the the finish and confirm with event staff that you have returned safely.

Out of Bounds
Some areas may be marked out of bounds. It is imperative to respect these boundaries to maintain our relationships with land managers. Participants MUST NOT go out of bounds. Any participant caught going out of bounds will be disqualified.

Course Closure
All participants MUST return to the finish by course closure time. If a participant does not return by course closure, event volunteers will begin coordinating a search party.

If you need a long time on the course, start as early in the start window as possible, wear a watch, and be prepared to cut your course short to make it back by the course closure time.

All participants MUST carry a whistle on the course. Complimentary whistles are available at the start tent (please only take one).

If you are injured on the course and need assistance, blow three long blasts to call for help.

If you hear a call for help, abandon your course to find the person in distress.

Part of the fun and fairness of orienteering is navigating your own course, so please be polite when you find a checkpoint and don’t holler that you’ve found it.
