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.


This venue will offer a combination of challenges with alternating terrain from the flats of the Shorecrest campus to the variable forests of South Woods Park and Hamlin Park.  The established trail systems and open forest within the parks will provide multiple route choices.  While we added a few new trails in this version of the map, there may be other minor social paths that are unmapped due to the dynamic nature of urban parks. For all courses, a safety bearing in any direction will take one to a road.

Of particular note, take extra precautions in and around parking lots and be mindful of vehicles entering and exiting for multiple non-COC events that are also happening on campus during our event. Please be respectful of other school and park users, especially ones entering the performing arts building at the North end of Shorecrest High School’s campus.

There is a mandatory crossing point all runners must use when crossing the NE 153rd entrance road to Shorecrest High School for Beginner/Elementary, Middle School, and JV Rookie/Advanced Beginner courses.

The map has been drawn to Sprint Standard, which has a different symbol set, especially with respect to trail designation, and is drawn to 1:4000 scale with 5-meter contours. Athletic fields sports fields have been marked as out of bounds, so please ensure that you do not use these areas as indicated on your map.

There will be a training area set up to the East of the main parking lot for those eager to increase their skills or practice.  Portable toilets will be located near the start area.  See the site map for additional venue details.

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.

Participating as a group? Just $5 for each additional adult (16+) group
member, no cost for additional minors.

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!


Public registration will close Wednesday 12/14/2022 at 11:59:00 PM.

There is no Day-of-event registration.

With its combination of varied contours and runnable forest, Hamlin Park was one of our favorite training maps for years. The contours remain, but the park has increasingly focused on planting new forest undergrowth–perhaps necessary in a popular city park that gets constant foot traffic. So today most contour recognition happens from the trails. There have also been some building changes since this map was last used for an event and the map updated.

Navigational Challenge: 5

Physical Challenge: 3



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.
