O-Fest Long

Sunday July 21, 2019

Larose Forest, ON

The Ottawa O-Fest will once again offer its favourite combination of a Middle event, followed the next day by a chase-start Long event. If you haven’t participated in a chase-start event before here’s how it works: on the first day (the Middle event) starts will be pre-assigned as is regularly done for pre-registration events. On the second day (the Long event) start times will be assigned based on results (by course, not category) of the Middle. The fastest person from the Middle will start first; if the second person was 20 seconds behind in the middle, they will start 20 seconds later. This means that the first person across the finish line (for each course) has the fastest combined time for Saturday and Sunday. O-Fest awards will be based on the combined Middle-Long total time.

The O-Fest Long event will be held on another new map, in another newly discovered forest – the Larose Forest east of Ottawa just north of the town of Limoges. The Larose Forest has a network of trails, and is popular with walkers and mountain bikers in the summer and local cross-country skiers in the winter. Relatively flat, and again free of rocky ground, it will be a fast, runnable forest for orienteers, but with some significant, rather steep ravines, setting us up for some great route choice legs.

Orienteering Ottawa looks forward to sharing our new discoveries with you!


Will be setup at the O-Fest on Sunday only, for the Long event.  They have a great selection of clothing and equipment for orienteering.
