Thanks to all of the volunteers this weekend and hope that everyone enjoyed getting out in the forest this weekend! Results are below:

Saturdays results from classic courses

Sundays results from adventure run



Come and join us at Ioco for 2 days of running on a competition class Orienteering map! This forest is more open than many around the lower mainland and has lots of pockets of really lovely areas. The area is crisscrossed with small trails, which provide detailed navigation challenges. If you attended the recent Forest Training series, it will test all your skills.

We will be holding events on both Saturday, July 17 and Sunday, July 18.

Event Details

  • Saturday, July 17 will feature classic orienteering point-to-point courses where controls/checkpoints must be visited in a particular order
    • Beginner - 2.3 km with minimal elevation gain - All controls/checkpoints on trail, with simple navigation. Good for people new to orienteering, and who would like to build confidence with navigation.
    • Intermediate - 2.4 km with minimal elevation gain - Most controls/checkpoints on trail, with a few easier controls off trail. Good for people newer to orienteering, but wanting some more navigational challenge than the beginner course.
    • Advanced - 3.4 km with fair amount of elevation gain - All controls off trail, with challenging navigation. Good for experienced orienteers who are comfortable navigating off trail.
    • Elite - 4.7 km with lots of elevation gain - All controls off trail, with challenging navigation and more physical. Good for experienced orienteers who are comfortable navigating off trail and with good fitness.
    • Participants can start any time between 11 AM to 1 PM.
    • All courses close and participants must be check in with the registration before 3 PM.
  • Sunday, July 18 will feature an adventure run, where participants can visit the controls in any order they like within a set time limit
    • 2 hour time limit.
    • Each control has different 'score' depending on the distance from the start and difficulty of placement
    • There will be a mix of controls both on and off the trails.
    • On trail controls should be suitable for newer orienteers, with some further controls providing an opportunity to stretch the legs a little.
    • Off trail controls will be a mix of easier and challenging placements, which will provide participants the ability to self-select difficulty.
    • Keep in mind that the trail networks include a lot of indistinct trails, some of which are mapped, and some which are not; See course notes below.
    • There will be a 'distanced' mass start at 11 AM, and individual starts allowed between 11 AM - 12 PM
    • Course will close and all participants must check in with registration before 2 PM
    • Looks like we have enough people Sunday to make this worthwhile!


Payment on site (contactless credit or debit card): $10/person ($5 for under 20 years old and max $20 for families).


We have permission to use the Canadian Pacific Trials Association (CPTA) parking lot off of the Thermal Plant Rd. Coming from Port Moody, once you are on Bedwell Bay Rd, take a left at the 3-way stop sign at Sasamat Lake onto Tum Tumay Whueton Dr. Drive up the hill and take a left near the top of the hill onto Thermal Plant Rd. The parking lot is less then half a km down this road on the left.

GVOC will have someone watching the gate to allow people in and out of the lot as it is not a public lot. We should have someone on site by 10:45 AM each morning.

Course Notes

The terrain at Ioco is extremely detailed, and can be challenging to read and navigate through. Additionally, there are many indistinct trails through the area which are created by park users and some of the trials bikers that use the area, some of which are on the map, and some which are not. The key to confident navigation in the area is largely dependent on using the features of the map that do not change over time: Contours and 'land' and rock/cliff features. Also be aware that some water features may be dried up, or at a different level than they appear on the map.
