Event #4a of 8 in the Ultimate Orienteer Series!

Our neighbors to the east, the Eastern Washington Orienteering Club, will host a weekend of orienteering in the Spokane area. The first day at Riverside State Park will include a variety of classic orienteering courses designed by John Harbuck.

  • Saturday, June 5 – Riverside State Park, Camp Seven Mile
  • Sunday, June 6 – Saltese Uplands


Ultimate class assignments and course details will be provided once the courses are finalized.

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.

Why is there a start window?

This event uses an interval start, which means that participants are started in waves instead of all at once. When you arrive at the start tent, find the chute for your course and follow the start volunteer’s instructions.

This Riverside State Park orienteering map was produced and is owned by our friends at Eastern Washington Orienteering Club.

Feeling a bit scuffed up from thick Western Washington forests? Take a trip to the east side to frolic through “white” open forest, and “yellow” open land. Camping and a gorgeous river are nearby, making it a real summer treat.

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.
