Map & Course Notes
All venues feature typical Mid-Atlantic ridge and valley terrain, varying in the amount of contour detail, with generally open, runnable woods. All venues are embargoed until the competition, as explained on the 'Rules and Awards' page. Competitors wishing to remain eligible for awards should refrain from visiting Oregon Ridge Park and Hemlock Overlook and Fountainhead Regional Parks before the event, except for participating in the model events and, for Fountainhead, using the mountain bike trail network (see Rules and Awards page for details).
Older versions of maps for the Long Day's Night venues can be found in two places. JPEG images can be found on the Resources page of this site; and RouteGadget links to both courses and maps are listed below.
Oregon Ridge Park (Routegadget) - last used for an October 2013 local event including the Susquehanna Stumble. The competition maps will feature relatively minor updates to capture new rootstocks, changes in vegetation and deadfall, etc.
Hemlock Overlook Regional Park (Routegadget) - last used for a May 2014 local event. This was a work-in-progress version of the middle distance competition map.
Fountainhead West (Routegadget)/Fountainhead East (Routegadget) - last used for a March 2012 and a January 2013 local event respectively. These are 1980s vintage maps with only minor updates since then; the UltraLong competition will use completely new maps of the same terrain.
Distances listed are approximate and subject to change.
There will be only one White, Yellow, Orange, Brown, Red and Blue course each day. Classes running Green courses will be split into Green X and Green Y for the Night-O and Middle Distance, but not for the UltraLong, as follows:
Green X = M50+, M55+, M60+
Green Y = M-18, M-Green, F-20, F35+, F40+, F45+, F50+ and F-Green
We reserve the right to modify these class/course splits based on registration numbers to balance the number of participants in the XY pairings.
General map notes: All maps will have 5 meter contour intervals. All maps will be oriented to magnetic north. A separate legend applicable to all maps will be available at registration. Competitions maps will not have legends printed on them. Clue sheets will be printed on the front side of all maps, and will also be available separately; for the longest clue sheets (Blue courses), the lengths will be 7.2, 6.1 and 7.1 inches for the Night-O, Middle and UltraLong courses.
Oregon Ridge - Night-O
The map will be printed at a scale of 1:10,000 for all courses except white and yellow (which are 1:7500). The safety bearing for all courses is north. There will not be water on the White or Yellow courses. The Model Map for this event/park can be downloaded from here or from our Resources webpage; the model map area is shown at both 1:7500 and 1:10000 scale.
General Terrain Description: the mapped terrain is dominated by a single large hill mass, rising from 110 m above sea level at the lowest point within the park to 194 m, carved by erosion into broad spurs and reentrants, covered almost uniformly with extremely runnable, high visibility mature deciduous forest, with a moderate trail network. To the north and northeast of the hill, the park is more developed for recreation, with parking, open areas and shelters for picknicking, areas of thicker vegetation, a denser trail network, playgrounds, buildings, a disused ski hill, and the remains of small scale quarrying and mining operations dating to the 19th and early 20th centuries.
Detailed Map & Course Notes
The forest at Oregon Ridge is generally open, with mature deciduous trees and little deadfall or undergrowth, and will afford very fast running. Denser vegetation is concentrated along the bigger creeks in the southern half of the park and it consists mostly of mountain laurel that can be passed through. Dark green areas are often masses
of convoluted deadfall and will slow runners significantly. The popular network of hiking trails stretching over ridges and along creeks is typically easy to identify. However, trails on flatter ground often receive sufficient leaf accumulation to make them practically disappear, this is especially true for smaller trails.
The park is divided roughly in thirds by two gas line rides overgrown with tall grass, oriented from SW to NE. The rides offer fast running on trails but steep inclines.
The park features large and frequently shallow reentrants, there are very few narrow ones. Therefore, runners won't have problems getting in and out of the reentrants. The main point features used for controls are root stocks, knolls, and rocks/cliffs. The knolls are mostly fairly small, ranging from 0.5 to 1 m in height. Cliffs and boulders are also below 2 meters in height.
The safety bearing is North for all courses: Once you reach a gas line ride, you can follow it NE or continue North until you reach the Shawan Rd or houses just South of that road."
Hemlock Overlook - Middle
The map will be printed at a scale of 1:10,000 for all courses except white and yellow (which are 1:5000) and Orange (1:7500). The safety bearing for all courses is west, in order to relocate (or wait) at the Occoquan shoreline. A Model Map for both Saturday and Sunday's events can be downloaded from here or from our Resources webpage; the model map area is shown at both 1:15000 and 1:10000 scale.
General Terrain Description: typical Mid-Atlantic spur and reentrant terrain, rising from 37 m above sea level at the Occoquan River shoreline to a high of 100 m, with moderate contour detail, some rock detail and a moderate trail network, denser in the northern third of the terrain where an outdoor education business offers ropes courses and similar challenges. Vegetation is varied with areas of light and medium green and deadfall but the terrain has good runnability and visibility overall.
Detailed Map & Course Notes:
The Middle Distance event will be held at Hemlock Overlook Regional Park, located near Clifton, Virginia. The park is bordered on the west and south by Bull Run Creek, which continues southeast towards Fountainhead Regional Park, the UltraLong venue. Access to the park is via Yates Ford Road, which enters from the east. Hemlock Overlook terrain is characterized by numerous closely spaced ridges and valleys, typical of Mid-Atlantic orienteering venues.
The advanced courses, and most of the Orange course, run through the roughly two-thirds of the park that lies south of the entrance road. The forest in this part of the park is generally open, with mature trees and little deadfall or undergrowth, and will afford very fast running. There are only a few trails in this area, which are well traveled and should be visible even with the recent new leaf accumulation. On these courses, climb is approximately 5% of distance traveled. The climb is an inherent feature of this terrain, although some small amount of climb may be avoided by navigating around large reentrants rather than through them. Even so, the courses avoid the steepest terrain, and unless there has been an unusual amount of rainfall, you should not have undue difficulty getting in and out of the reentrants.
The White and Yellow courses are confined to the area of the park north of the entrance road. The forest can be quite dense in this area, but there is a good trail network, and a variety of large features and handrails. There are many large objects in the woods constructed of wood and rope, and marked with the X symbol on the map, and a few of these are used as control features. There may be temporary shelters or teepees erected in the open fields, which are not mapped.
There are two starts: one for White, Yellow, and Orange, and the other for Brown, Green, Red, and Blue. The White-Yellow-Orange start is a short (500m) walk from registration, accessed by walking north along a power line/cut from the entrance road just west of the parking area. The start for the advanced courses is approximately 1.5 kilometers from the registration building. The walk to the start includes about 1.2 km along a trail that crosses a small creek and has about 30 meters of climb. Allow 20-25 minutes depending on your walking pace.
You may hear gunshots when you are out on your course. You can safely ignore them. The rifle range is located across the river from the park, and poses no hazard to runners. There is no hunting allowed in the park itself on the day of our event.
Fountainhead - UltraLong
The map will be printed at a scale of 1:10,000 for all classes except F-21+ and M-21+ (both at 1:15000) and those on White or Yellow courses (both at 1:5000). Classes running white or yellow courses will have interval starts. All other classes will have a mass start. The safety bearing for all courses is south, in order to relocate (or wait) at the Occoquan shoreline. A Model Map for both Saturday and Sunday's events can be downloaded from here or from our Resources webpage; the model map area is shown at both 1:15000 and 1:10000 scale.
General Terrain Description: typical Mid-Atlantic spur and reentrant terrain, often fairly steep, rising from 37 m to a high of 93 m above sea level on the north side of a reservoir formed by damming the Occoquan River. Generally high to extremely high runnability and visibility, with patches of thicker vegetation and deadfall in varying quantities and of varying size. Trail network varies from sparse in less visited portions of the terrain, to moderate, to very dense, particularly in a section containing ~10 miles of twisting singletrack for mountain bikers. Moderately intricate contour detail in small portions of the terrain but topography is mostly characterized by distinct, large to very large spurs and reentrants with subtler contour variations indented here and there into their sides.
Detailed Map & Course Notes:
The mostly wide-open Fountainhead ridge and valley forests are a real joy to run through. However, up-front so that you don’t miss it, here are a few words of caution:
