Race Details

Categories and Courses

There are three types of course / category you can sign up for:

Male / Female age classes
Race against your peers on the assigned course over two days of competition. The top 3 overall in each class will be recognized with prizes at the end of the weekend.  The top 3 eligible finishers in each class will receive Ontario medals.  Here is how eligibility is defined by Orienteering Ontario:  "You are eligible for the Ontario Orienteering Championships if you are a member of an Ontario orienteering club OR if you are an Ontario resident who belongs to any orienteering club affiliated with Orienteering Canada."
Open classes
Choose the course you want to run - results will be kept and published but no prizes will be awarded.
Recreational course
A 'score-O format' course for those who want to choose how long and how hard to make the course as they go - no results will be kept or published. 

Course / Class Table

Age classes are assigned to courses based on the following table. If you wish to run a higher numbered course you may sign up for a more competitive age class. Open classes are available on courses 1 through 5.

Course Descriptions

If you are planning on signing up for an open class or are considering competing in an older or younger age class the following table contains information about each course to help you decide what class to register in.

Sat., Sun.
Approx. Length
Approx. length
1 Beginner 20 min, 30 min 1.5-2.5 km 1.5-2.5 km
2 Easy intermediate 20 min, 30 min 2-3 km 2-3 km
3 Hard intermediate 25 min, 50 min 2.5-3.5 km 2.5-3.5 km
4 Advanced, physically less challenging 25 min, 45-50 min 2 km 3.5 km
5 Advanced 25-30 min, 45-50 min 3 km 4-5 km
6 Advanced 30-35 min, 60-70 min 4 km 7-8 km
7 Advanced 30-35 min, 80-90 min 5 km 10-12 km

*Recommended winning times (from Orienteering Canada guidelines).
Courses will be designed so that the fastest person on the course completes in roughly that amount of time. The approximate lengths shown above are what the resulting courses will likely be, based on how navigationally and physically challenging the terrain is.

Recreational Courses

There will be a Recreational Course on Saturday morning, for anyone who wants to get out in the forest, but not be restricted to a particular point-to-point course.  The Recreational Course will be in Score-O format - you can find as many of the controls as you wish, in any order, in a pre-set amount of time.  If you are new to orienteering, this is a great way to experience the atmosphere of a big meet without the pressure of a competitive course.  Start of the recreational course will be a mass start at 11 AM.


The Carp Ridge is made up of forested, rocky ridges, with many large and small marshes and a fair bit of rock detail. Beavers are active in the area with many beaver ponds and dams. Some sections have an extensive trail network and other areas are completely wild and undisturbed. The ridge is mapped with 2.5m contours to reflect the intricate topographic details. The relief is often rather vague and hills are less than 10 metres high. The area has a mix of runnability from hardwood forest to denser vegetation. The result is a very technically challenging area that will be a great test of your navigation skills.

This year's courses will cover very similar areas as last year's North American Championships courses. Here's what last year's middle distance course setter, Andrew Cornett, had to say:

"While the mapped terrain does not include any large hills, there is no shortage of smaller hills, knolls and subtle contour detail. Marshes, ponds and small lakes are also plentiful. If the fine dry autumn weather continues until race day, most of the indistinct and even the distinct marshes will be relatively dry. Beaver dams, which are mapped using the earth embankment symbol, are generally crossable. Runners will encounter cliffs, rock faces and boulders scattered throughout the area. Only boulders >1m high and cliffs / rock faces larger than 1m high by 5m long are mapped. Some areas feature a dense trail network while other areas are entirely devoid of trails.

In early October these woods are a living palette of rich and beautiful colour. The runnability of the forest is mixed. As usual the relative runnability of the woods is mapped using white (fast) and three shades of green (slower). The boundaries / transitions between the various forest densities are generally gradual and indistinct. Visibility should be quite good on race day as many of the leaves will already have fallen. However, the carpet of colourful leaves on the forest floor can make it difficult to recognize indistinct trails and smaller indistinct marshes.

There are numerous clearings of various sizes in the terrain as well as some abandoned fields. The abandoned fields are generally overgrown with goldenrod and other wild plants, including sharp raspberry canes. In some of the clearings where the ground is rocky, runners could be slowed by the presence of juniper bushes. The juniper patches are indicated on the map by vertical green lines (dense undergrowth symbol).

There are several maintained and ruined fences in the terrain and they are indicated on the map. Some of these fences are/were constructed from barbed wire. Although we have worked diligently to mark the fences with survey ribbon in areas where runners are likely to, it is likely that some loose strands of barbed wire have evaded us. Please watch out for ribbons and use caution near all fences."

Alex Teutsch enjoying the Carp Ridge terrain more than his expression indicates.


We ask that participants not orienteer or explore the Carp Ridge north of Thomas Dolan Parkway. Not only is it not fair to competitors from outside of Ottawa who can't also explore the area but most of the area is privately owned and crossing those lands without permission is trespassing. We have worked hard to create a positive relationship with these land owners and gain permission for hosting events on their land. We don't want that jeopardized by wayward orienteers running around the Carp Ridge whenever they feel like it.

Old Maps

If you want to see an old orienteering map (made in 2014) of the competition area look through these courses from last year's NAOC2014 middle and long distance races. The courses should also give you an idea of what to expect this year though the 4 advanced courses were spread over 8 or 9 courses last year.
