UPDATE SATURDAY 10PM: The MTBO part of this event has been CANCELLED due to overly wet trail conditions. The classic/foot orienteering will take place at the (same) timing shown below. We hope to reschedule the MTBO in the near future.
Welcome to QOC's National Orienteering Week event, where you just might win a prize randomly as well as have fun orienteering!
Everyone is welcome at the two one events taking place here on Sunday, Sept. 22. In the morning, weather permitting, bring your bikes and choose between short and long mountain bike orienteering ("MTBO") courses; start anytime between 8:30am - 10:15am and be done by 11am. Then during our regular 'start window' (11am - 1:30) walk or run on foot your choice of a beginner (white or yellow), intermediate (orange), or advanced (brown, green, red) orienteering course.
New to orienteering? We will hold beginner clinics continuously as needed during both events; just tell the friendly folks at registration if you'd like to be in one and they'll take care of you. Also, make sure to check out our Your First Event and For Beginners webpages, and if they don't answer any question you have, just use our Contact Us form and ask away!
Group Leaders: please see our For Group Leaders webpage and then contact us so we can get you registered in advance.

| Course Notes |
The Lake Accotink map as used for both the MTBO and the regular orienteering course will be at a scale of 1:7,500. A few trails are a bit faded and overgrown from lack of use. Vegetation is some areas is thicker than mapped, but the courses should be fairly runnable. The trails are fairly popular for mountain biking so all runners should be aware of bikers. There is a very dense network of trails in the park. Because they were built by mountain bikers, many of the newer trail tend to loop around.
The MTBO course distances are a rough estimate of the optimal route on trails (in other words, the straight line distances are less and are not shown). For this MTBO event, no shortcutting through woods is allowed, either on the bike or carrying it - you must stay on trails at all times. The MTBO will have the same start and finish as the foot-o. The courses will be mostly on narrow singletrack trails within the park. The courses will have some sections with short, steep uphill and downhill terrain that will require some skill to ride. Obstacles such as downed trees generally have log ramps built up or an alternate ride around. You will probably need to walk bikes over some of the newer downed trees blocking some trails. |
