Mason Neck Pre-registration is required for this event, opening Monday, Jan. 22 at 6pm and closing Saturday Jan. 27 at 12 noon.
There will be no day-of registration.

Get ready for another fast-running, mid-winter event at club favorite, Mason Neck State Park!

Orienteering at Mason Neck provides a distinctive navigation experience due to the flatness of this coastal plain terrain. The park's subtle contours (2.5 meter contour interval rather than the standard 5 meters) and subtle features present a change from the usual Northern Virginia spur and reentrant terrain. At Mason Neck you'll enjoy the chance to develop your compass skills and pace counting. Runners have their choice of a full set of classic courses (details below) thanks to Will Hubsch who has set courses for LAOC in the past, and now, having come east, has volunteered to be a course setter for QOC. In addition, the map has improved thanks to QOC's Mark Thomsen, who has made selected updates to the map following last year's event.

Also, to help those new to the very useful skill of pace-counting, we will set up a 100 meter pace course. Those interested will be able to get some instruction/recommendations on how to calculate your pace and employ pace-counting most effectively.

Check in will be on the west side of the main parking area as usual. Follow QOC signage from the turn off of Gunston Road.

From southbound I-95, take exit 163 (Lorton). Go left onto Lorton Rd at the end of exit ramp. Go under the 2nd overpass and turn right onto Lorton Market St., then go about 1.5 miles to the traffic light at Route 1. Go straight through light (the road name changes to Gunston Rd) and go about 5 miles to the right turn on High Point Road (it's about 1.2 miles after the Pohick entrance). Once in the park ($10 entrance fee per vehicle), follow the signs towards the Visitor Center. The registration area will be to the left just before the Visitor Center; look for the banner.

Course NotesClassic

The terrain at Mason Neck is very flat, open, and will present a challenge staying in contact with the map. Some courses run on the longer side distance-wise, but the good runability, great visibility, and limited climb should make running times fairly standard. Controls are reasonably far apart from each other, but please check your codes when punching. The Blue course is unique in that it has two separate loops, where runners will visit a control twice. Many controls belong to several courses, with runners entering and exiting from different angles, so hopefully you'll see a lot of folks out there running every which way. The contour interval is 2.5 meters.

I've tried to set courses that thread the needle between interesting and fair, given the lack of features, and have leaned towards having quite a few controls to keep things exciting. The key here will be knowing when you need to know your exact location and when you can just run to a catching feature. If you use pace counting, this might be the map to put it to the test. As with many maps, not all rootstocks are mapped, and conversely, some mapped rootstocks are no longer as obvious as they once were, so keep that in mind.

The visibility of marshes and watercourses fluctuates quite a bit based on recent rainfall, and it looks like rain is in the forecast for the week leading up to the event. Keep in mind that the open marshes along Kanes Creek on the north edge of the map may be totally impassable if there's been recent or significant precipitation. All courses will cross High Point Road (the paved road you came in on) at least once; please use caution when crossing it. All courses will start at the turnaround circle 50 meters northwest of the registration/download area.

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.
  • There is no planned, on-site beginner instruction, but beginners are encouraged to watch relevant videos such as this one created by QOC's instructional guru David Onkst
