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!

Make it a weekend doubleheader! We have Choose Your Adventure: Corn Maze on Sunday, October 1st!


CascadeOC is celebrating its 40th Anniversary this year, so we’ll have a special format for this one!

Like usual, 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!

Map 1: Time warp! This is a 12-checkpoint, point-to-point, course from 1980! We’ll be using the club’s original map from 1979 (the club’s first color map!), with the course drawn on top in red ink. We’ll also be using manual punching, too! In order to continue to Map 2, you’ll need complete this course. The point-to-point distance is 4.1k and the map scale is 1:5000. This course also involves crossing West Green Lake Way (northeast side of Woodland Park), so be careful when crossing. There are crosswalks to cross safely.

Map 2: Back to the future! 12 more checkpoints. You can get as many as you like which you can get in any order, as many you can until time runs out. This map will use the current map (1:4000) and will use e-punching.


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!

Woodland is a wide-open park of gently rolling hills (lots of them), mowed grass, and runnable forests, interlaced with paved and gravel trails. It is a popular cross-country venue for its varied terrain and fall colors, and popular orienteering venue for the same reasons. It is the location for the club’s National Orienteering Week event each year, and a great place to start practice contour recognition and compass skills.

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.
