March 10

Greenbelt Park Sign Pre-registration is required and will open on Monday, March 4 at 6pm and will close at Noon Saturday March 9.
There will be no day-of registration.

Welcome back to Greenbelt Park! After a major windstorm a couple years ago knocked out several sections of the park, we were not able to hold an event in Greenbelt in 2023. We are excited to be back this year at one of our closer-in locations that is accessible to a wide range of participants without a long drive.

Come out and enjoy a great selection of classic courses designed and set by Russ Damtoft and Mike Manteuffel (details below). Parking for this event will be at the Sweetgum Picnic Area, which is not far from the Greenbelt Road park entrance. We will be registering and starting from the Sweetgum picnic area. The Sweetgum Picnic Area is open with little tree cover, so bring appropriate cold and wet weather gear for early March. The start and finish are located near the main area and they are the same for all courses, White through Red.

Check in will open about 9:45 a.m. and courses will open at 10:00 a.m. As always, please be off the course no later than 3 p.m. and remember to download at our e-punch station even if you did not finish. We want to make sure of everyone’s safety and status.

Daylight Savings Time Reminder! Make sure to set all non-auto-adjusting clocks ahead 1 hour Saturday evening. Don't show up late!

Free Beginner Instruction will be offered, but please reach out to the Event Director if you have a large group, so we can plan accordingly. Also, make sure to check out our Your First Event and Orienteering Techniques For Beginners webpages, and if they don't answer any question you have, just use our Contact Form and ask.

String OFor The Kiddos! Come and try the free "string-O". What's a string-O, you ask? As their first step towards becoming an orienteer, kids follow a course marked with string in a small area to find their favorite Disney characters (under parental supervision). Minimum effort for parents, maximum fun for kids!

Post-Event Social: After your run, join fellow orienteers at Yiayia’s Kitchen, located here just 4.3 miles northwest of the park, and with map as proof and a purchase, get a free drink and dessert!

Course NotesClassic

There was a massive windstorm in 2022 which took down a large number of trees. Most fell to the east. That aside, the forest continues to mature with pines falling over and being replaced with deciduous trees. There are still lots of individual strands of greenbrier throughout the forest, but it’s not as bad as in years past.

The area has been partially remapped this spring. Rootstocks that are mapped are larger than about two meters, but be aware that there are many unmapped rootstocks because of the storm. Areas mapped in green can be any kind of vegetation: mountain laurel, small saplings, greenbrier, or fallen trees. Solid color greens are used for living vegetation; slashed lines are used for fallen debris/trees. All courses (except for white) will be affected by dense vegetation on at least one leg. Thorn protection (gaiters or thorn-resistant pants) are recommended for orange courses and above. Black circles are sewers; some flush with the ground but most raised by one to two feet. Black X's in middle of woods are the remains of homeless camping areas (trash or old tents) and are not necessarily reliable features as these come and go.

There has been serious erosion in stream areas and most streams have earth banks even when not mapped as such. The courses are designed to avoid those which seemed uncrossable, but advanced orienteers should be aware of them, especially when making creative route choices!

Important Notes
  • If you wish to become a QOC member you should join online in advance via this webpage (which also explains the member benefits). Membership is completely optional.
  • Most of our events use an 'epunch' timing chip for electronic timing. Individuals or groups without their own epunch will be loaned one for that event. Loaned epunches that are lost incur a $40 replacement fee. Epunches (also known as SI-cards or finger sticks) can be purchased from online vendors as described here.
  • Former QOC members who have let their membership lapse pay non-member fees.
  • Compasses are available at no charge, but if lost incur a $15 replacement fee.
  • Please provide collateral (such as car keys) when borrowing a compass or epunch.
  • Beginners are encouraged to watch relevant videos such as this one created by QOC's instructional guru David Onkst
