Our Schedule

Registration for most GCO events opens at 9 a.m. and closes at 12 noon. Starting Times are assigned from 10 a.m. to 12:30 p.m. Beginner Instruction is offered as requested. Hint: Come anytime between 9 and 11 to have time for instruction and a course.

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 plus a refundable $5 deposit.

We offer online registration for most 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.

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.
