Winter League is the Pacific Northwest’s premier competitive orienteering series for all ages.

  • Elementary, Middle School, High School and College students compete under the banner of the Washington Interscholastic Orienteering League (WIOL).
  • Winter League public courses offer a range of categories from a competitive long advanced category to non-competitive beginner-friendly categories at every event!

Elementary/Beginner  11 1.1 km 5 m
Middle School     10 1.5 km 10 m
JV Rookie  12 1.7 km 10 m
JV Girls/Intermediate   14 2.6 km 20 m
JV Boys     14 2.6 km 20 m
Varsity    24 3.9 km 30 m
Short Advanced   24 3.9 km 30 m
Intercollegiate/Long Advanced 28 4.8 km 35 m

Note: For this event, all courses were measured “sprint-style”, meaning that the above distances are the shortest possible that go around impassable objects such as buildings, fences, and out-of-bounds areas. 

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.


  • After the first two Winter League events that were in city parks with forests, orienteering at South Seattle College will feel quite different! At only about 50 acres, the event area is quite small, but it packs a punch. In the center of the map, there’s a dense collection of campus buildings intermixed with courtyards and pathways. Surrounding the more complex urban areas are open areas with trees and thickets. On the north end of campus, there’s a small arboretum area with winding and crisscrossing paths among landscaped areas.
  • This venue was mapped to the “sprint standard” (ISSprOM), so make sure you know what symbols are illegal to cross. Namely, the thickest black lines (tall fences, tall retaining walls) and olive green areas (generally nice landscaped areas). It is also illegal to enter buildings (dark gray), but knowing the light gray symbol for open-air canopies and walkways will be useful; the start chute and finish chute are under two of them!
  • The courses are very “sprinty” and winning times will be fast. The map scale is 1:4000, there is very high feature density, so things will come up quickly! The venue is quite flat and comparatively small, and courses are a little shorter than usual.  Despite being shorter in length, the courses have a lot of controls, with a variety of leg lengths to mix up the tempo a bit. We gotta keep ya on your toes!
  • Pay attention to your control codes! There are 60 controls out there in such a small area, some as close together as 15 meters. You will likely see many flags that aren’t yours!
  • Note: for Intercollegiate Varsity/Long Advanced runners, if you’re using or renting an older SI-5 e-punch, those only hold 30 control punches. With a 28-control course, your e-punch only has room for 2 erroneous punches, so COC will loan out free high-capacity SI-sticks if we see you qualify. You need to pick them up at Info Tent BEFORE you are called to the start line.
  • Because the area is quite small, JV/Intermediate courses and above will cross over themselves several times. The Long Advanced course crosses itself a whopping 13 times!
  • The courses for High School Varsity, Short Advanced, and Long Advanced/Intercollegiate Varsity will visit the arboretum area, where there are two things of note:
  1. These courses have been designed so that runners entering and exiting the arboretum will be separated from most vehicles arriving, departing, and driving through the parking lot. Be aware that there may be other vehicles driving along this part of the course, but most event attendees will not be driving here.
  2. In the arboretum, there is a lot of out-of-bounds olive green on the map, which are landscaped and curated areas of the garden. If you’re on a path or grass, you’re good to go!
  • South Seattle College is a technical and mechanical school, meaning that there is a lot of vehicles, machinery, and construction equipment and supplies parked or placed in various locations, especially in the eastern part of campus. Expect to see cars, trucks, semi-trailers, or even a few small airplanes! These objects are generally not mapped, as they change frequently and are not permanent fixtures. Take care when traveling around or through these areas!

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 1/25/2023 at 11:59:00 PM.

There is no Day-of-event registration.

Physical Challenge: 2/10


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.
