Welcome to the Winter Orienteering Series

The Winter Orienteering Series was established in the winter of 1992-93 to provide a focus for the winter orienteering season, and to provide participation for adults and families along with Washington Interscholastic Orienteering League (WIOL) participants. Winter O' Series meets are held in conjunction with WIOL meets.

The Basics

The Winter Orienteering Series consists of seven regular season meets, plus one championship event at the end. Each event offers courses ranging from beginner to advanced, so as you improve your skills throughout the season, you can continually challenge yourself with more difficult courses.

  • Beginner
  • Intermediate
  • Short Advanced 
  • Long Advanced

While the Winter O' Series consists of eight events, each meet is a stand-alone event. You don't need to pre-register and you don't have to commit yourself to attending every event of the season. Just show up when you want and participate, even for the Championship. However, preregistering does help the meet run better, so we reward that planning on your part with a discount at each meet registered online (http://register.cascadeoc.org) and a free meet if you preregister for the whole season.


For the Advanced Orienteer: The Season

If you run Long Advanced as an individual at any regular season Winter O' Series event, you automatically earn points towards your season score. Points are based on your order of finish, and men and women are scored separately (but compete on the same course). At the end of the regular season, which consists of seven races, your best four scores are combined to arrive at your season score. The three men and three women who finish with the highest season scores receive awards!

For the Winter Orienteering Series, regular season points are awarded as follows:

  • 1st Place: 100 points  
  • 2nd Place: 95 points 
  • 3rd Place: 92 points 
  • 4th Place: 90 points 
  • 5th Place: 89 points 
  • 6th Place: 88 points, and so on. 


Tie-break Method

If, after the final series event, two or more competitors have the same total score, the tie is broken as follows:

  1. The individual with the highest individual event score wins the tie
  2. If the highest individual score is equal, the next highest individual scores are compared; comparison continues in this manner until the tie is broken
  3. If all individual scores are equal, the result is declared a tie


For the Advanced Orienteer: The Championship

The Winter O' Series Championship event is held in conjunction with the Washington Interscholastic Orienteering League Championships in February. This is a winner-take-all race where regular season results don't matter! Just run Long Advanced as an individual and you're eligible to win the Series Championship!
