We’re bringing back Founders’ Day! For those who’ve been around the club for a while may remember that we organized Founders’ Day (which started out as the Bo Powell & Mac MacDonald Memorials), usually in October, from 2001-2011. Last year, at our club’s 40th anniversary celebration, we awarded Debbie Newell with the first ever Founders’ Award for her service to the club. This seemed like a great reason to reinvigorate Founders’ Day with our annual race with subsequent annual club meeting at 1:15pm!

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 10:00am – 11:00am for up to an hour of free skills instruction!


This event was originally planned for Woodland Park, but due to a conflict, we’ve moved it to North Seattle College. We’re still going to keep the twist, though!

We’ll have another twist this year: Dog Bones!

Like many Choose Your Adventure events, there are 24 checkpoints in the park, 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 11:15am and the time limit running out at 12:30pm.

But here’s the 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.)

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!

Which way is up and which way is down? North Seattle College will have you asking this question. Featuring the unique opportunity to figure out whether you need to be “upstairs” or “downstairs,” and wonder whether there will be a wall or a pass-through when you turn the corner.

CascadeOC’s annual meeting! Pizza will be provided for club members who want to hear about what the club is working on!  1:15pm at the Phinney Community Center (6532 Phinney Ave N, Seattle, WA 98103).


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.
