We return for the penultimate meet of the 2012-2013 QOC season to Mason Neck State Park, known for it's water views and fast, flat terrain (and 5 foot contours). Bring a bike or canoe (see below) and enjoy the park after your run, or cool off in the renovated Nature Center. Event registration will be from 10:45am - 1:15pm, you can start your course anytime between 11am - 1:30pm, and courses close at 3pm. Course details are now posted below.

Ample parking and flush toilets are available at the assembly area. A state park entrance fee of $4 per vehicle will be collected upon entrance to the park. We will also hope to have the use of a large (pavilion style) tent, so feel free to bring food or beverages.

Mason Neck Woods Any youth or large groups attending, please contact the Event Director so that we can coordinate pre-registration for your group; the group registration and waiver form is part of the information on our Group Leaders page.

Mason Neck State Park is also a great place for exploration on the water or by bike (a very smooth and family-friendly bike path runs through much of the park). Of note:

  • Bring your own canoe or kayak, or rent one. Rental rates are $10/hr for a kayak, $15/hr for a tandem kayak, and $12/hr for a canoe (all + tax).
  • A 2.5 hour guided kayak tour is conducted on Sunday mornings at 9am. Cost is $15 per person; reserve a spot by calling the park office at (703) 339-2385.
  • Bring your own bikes, or rent one. Rental rate is $5/hr.
  • There's a fine playground quite near our registration area.
  • Dogs are welcome in the park, but must be on a leash of length 6 feet or less at all times and "with a human on the other end", as a park ranger said.

Course NotesClassic Orienteering

Map scales: 1:5000 for white, 1:7500 for yellow and orange, and 1:10000 for all advanced courses. Map size: green, red and blue are on legal size paper; all other courses on letter size. Map Note: due to many changes in rootstock abundance and location, none will be shown on the map. You'll see plenty of them, thanks to the storms over the past few years, but no controls are on them either. In general: There is good visibility in the terrain. The advanced courses have relatively few (feature) details compared to other parks. In some areas, the vegetation is quite bushy and the green-mapped areas are really difficult to run through. The marshes are wet at the moment (due to recent rain). Some of the knolls on the map look more like old rootstocks with moss on the top. Course distances are listed based on "straight line" measurements, but you'll run further due to having to go around bays and marshes.
