Head on out to Madrona K-8 School (9300 236th Street Southwest, Edmonds, WA) with your smart phone charged and the UsynligO app downloaded.

Learn more about the UsynligO app and how to use it here.


Courses are posted on UsynligO. When in the app, search for Madrona. The controls are relatively close together so it may work better to change the control radius from 20m to 10m, and set the Minimum GPS accuracy to 200 m. The maps are available in the app, online when you have found the event, or linked below. If you want to print separate control descriptions, they are here.

How are courses measured?

Courses are measured as the crow flies, in a direct line from control to control. Unless you have wings, you will travel farther than this distance! Courses are measured in kilometers, so a good rule of thumb is to simply round up to miles to estimate how far you will go. So in a 5 kilometer race, you’ll likely travel up to 5 miles.


The courses are open whenever school is NOT in session: after 4:30pm on weekdays, anytime on the weekends, and any day during summer break.


There is no fee to participate.


Registration is not required.


Please park at the north end of the main parking area.


Madrona School is a more complex variation of the typical non-college school map, with buildings and a few prominent trails on a large scale map (1:2,500 scale). But in this case, there are two campuses, linked by several trails on a steep slope. This doubles the ability for campus sprint course design, while also providing a physical challenge on the slope.

As an operating elementary/middle school, it should not be used during school hours.

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.
