Our Schedule

NEW schedule times!!! Registration for most GCO events opens at 8:30 a.m. and closes at 10:30 a.m. Starting times are assigned from 9 to 11 a.m. Beginner Instruction is offered as requested. Courses close at 1 p.m.

Our fees: $10 for each adult and $5 for each child or youth (ages 7-18) for non-members and $8 for adults and $4 for children or youths for members of GCO or other Orienteering clubs.

A second course is $2 per person. You can also rent a compass for $1.

We offer online registration for some meets! This will save you time, plus give us a better count for printing maps. Here's how it works:

  • You can register and pay for your first course of the event.
  • You can buy a GCO membership, for discounted event fees.
  • You can rent a compass.
  • If you register online, you also have to pay online, using a credit card.
  • To further help speed things along on the day of the event, our liability waiver is available during checkout.

If you sign up online, and make sure to complete all the information in the signup process, you will be able to simply walk up to the check-in table. No additional paper forms, no waivers; it's all done online.

NOTE: There will be NO online registration for the Sept. 29 meet at Orangevale.

You can save time, particularly for groups, by filling out a Registration Form (left). Use ONE FORM for each individual or team going out together!!

PRE-REGISTRATION OPTION FOR GROUPS such as JROTC or Scouts with multiple teams. Contact the Event Director for each meet on the possibility of emailing your list of teams and courses a few days before the meet to save time.

Meets and Events

Saturday, Sept. 29, Orangevale Community Park, Orangevale. W, Y, O; ED/CS: Mats Jansson, , 916-220-0224.

Our fall season is kicking off with a three-course event at Orangevale Community Park (Oak and Filbert, just east of Hazel). As usual, we have partnered with the NJROTC program at Casa Roble High School. The cadets will be running the show, thanks to Chief Kevin Houdek.

The park is a small but diverse gem right in the middle of suburban Orangevale. It is heavily used, so you will see adults and kids engaging in soccer, horseback riding, picnics and playground use. There is also a popular disc golf course on the western edge of the park. That course is marked out of bounds on the map; do NOT go there!

Within its small boundaries, you will encounter not only sidewalks and open fields, but also a winding creek going through an oak woodland. You will probably hear or see some wildlife, including acorn woodpeckers and red-shouldered hawks.

We will have the following courses:

  • Beginner (White): 1.9 km
  • Beginning intermediate (Yellow): 2.5 km
  • Intermediate (Orange): 3.2 km

We have sent a strong message to the yellow jacket (wasp) community to stay inside. Seriously though, we have had events here several years without problems, so last year's encounters can only be chalked up to bad luck. But we will avoid the specific place where we found them this year.

Note the different schedule (NEW for this year):

  • 8:30 - 10:30 Registration open
  • 9:00 - 11:00 You can start your run during this time window
  • 1:00 You have to finish by this time
