This event has been cancelled because the venue is already soggy and with the rain forecasted for tonight and tomorrow, there is potential for damage, and we don’t want that to happen, especially not with a first time venue.
Welcome to the first event in the 2025-26 Winter Wednesday training series on a new map of Foster Golf Links in Tukwila. We offer an Easier and a Harder course. The Easier course will be suitable for orienteers with less experience navigating at night and can be completed by staying on the golf cart paths. The Harder course will be a significant step up and, given the flat and open nature of the terrain, is designed to encourage direct routes between controls. The Harder course crosses many golf cart paths but rarely follows them. Please see the Winter Wednesdays series page for more on the goals and philosophy of these events. Instruction and coaching happily provided on request. More info on the event page. Pre-registration only; registration closes on Tuesday night.
