Start Procedures

            Clear and check your SI card when you arrive in the start area.

            You will be called up 3 minutes before your scheduled start.

            2 minutes before your start, you will move forward and may pick up loose control descriptions.

            1 minute before your start, you will move forward to the map line.  You may mark your name / number on the back of the map.  Do not look at your map.  You may ask the starter to check that it is the correct course.

            When the beeper sounds, you punch “start” and pick up your map.

            There may be a short streamered run to the start triangle shown on your map (to be determined).  You must run to the triangle.  There is a flag but no punch at this point.  At this point you may begin navigating to your first control.


Drinking Water on Courses

            There will be at least one control with drinking water on all courses of orange length and above.  Please use the cups provided and dispose of them in the bag or bin provided.


Time Limits

            Time limit will be 2 hours for all courses.


Friday, Apr. 6 – Pyramid Hill Sculpture Park

            Middle Distance

            Scale 1:10,000, Contours 5 meters

            Course Setter: Pat Meehan


            Consultant: Don Davis

            Walk to Start:


            Notes: Pyramid Hill is on the hills overlooking the Great Miami River and city of Hamilton.  The park has large mowed meadows, with more than 50 monumental sculptures, several buildings, and a network of roads and trails.  There are several wooded areas, ranging from very open in the developed parts of the park, to quite thick around the outer edges.  The terrain is hilly, and steep in some areas.

            Course Setter Notes: to come


Saturday, Apr. 7 – Meadow Ridge Area of Elk Creek MetroPark

            Classic Distance

            Scale: 1:10,000, Contours 5 meters.

            Course Setter: Mike Minium

            Vetter: Matthew Robbins, Dave Waller

            Consultant: Don Davis

            Walk to Start: less than 250 meters from event center

            Toilets: Portable toilets at parking lot / event center.

            Notes: Elk Creek MetroPark consists of two distinct areas.  Meadow Ridge is a former 36 hole golf course and the area still has many golf course features such as paved cart paths.  The grasses are being allowed to grow, but runability on the former fairways is still open and fast.  Native prairie grasses have been planted in a few places.  The Meadow Ridge area is not yet open to the public – we will have exclusive use.

            Around Meadow Ridge to the west and south, steep and densely wooded hillsides descend some 60 meters to the flood plain of Elk Creek.  A couple horse trails traverse the hillsides.  The Elk Creek flood plain consists largely of open fields and park land with a dozen or so picnic shelters.

            Course Setter’s Notes: The golf course is very runnable and very fast.  Most of the fairway and rough has been mowed short.  There are a few patches of tall rough which may have a few thistles or brambles.  Advanced courses will briefly venture into the steep and thickly wooded hills surrounding the course, but 90% plus of all courses should be very fast terrain.

            Green circles and green dots have been used for single trees and a few large shrubs.  In a few cases I thought I’d have used a dot instead of a circle for a particular tree, but in general I stayed with the mapper’s original representation.  Some single trees may have a clump of bushes around the base but are just mapped as a single tree, not as a copse.

            Small patches of white “open forest” are sometimes as few as 2 or 3 single trees with interlocking canopies, but open grass underneath.  Like the distinction between green circles and dots, the mapper made a decision; not everyone will agree on how they would have mapped every particular tree or copse.  In general, if canopies of 2 or more trees connect, they are mapped as white, although in a few cases, especially conifers, they are mapped as individual circles.

            Larger patches of white forest are very runnable, but may have some light deadfall or undergrowth.  Watch out for newly planted 1-2 meter tall trees in these areas; the park has been planting native seedlings to replace hundreds of mature trees killed by emerald ash borer.

            The very few boulders on the map are small but quite obvious, most are only about 0.5 meter in height.



Sunday, April 8 – Voice of America MetroPark

            Middle Distance

            Scale 1:10,000, Contours 5 meters.

            Course Setter:


            Consultant: Don Davis

            Walk to Start: 1 km flat paved path

            Toilets: Indoor toilets at event center, portable toilets by parking lot.  No toilets at the start

            Notes: Voice of America is a relatively flat area, that was mostly fields until a few years ago, that are now overgrown with tall grasses and other vegetation.  A dense network of trails for cross country running and skiing or just walking and jogging wind through the fields. The transmitter towers for the Voice of America radio station were here, and large concrete “boulders” that supported the towers hide in the fields.  There are a few areas of woods, some small wetlands and ponds, a manmade lake, and a manmade sledding hill.

            Course Setter’s Notes:  Large sections of VOA are meadow / prairie area.  The mapper has mapped almost all rough open area with closely spaced vertical green lines (undergrowth, difficult to run).  These areas have varying quantities of thistle, and an occasional bramble.   In general, I would have mapped most of them with widely spaced lines (undergrowth, slow run), and there are also places you can cross quite easily.  The best tip here is to look ahead to judge the density of thistle and possible thorns.

            Dark green has been used for both thick woods, but also areas of meadow / prairie that have become very densely overgrown with low bushes and thorny vegetation.  At a quick glance, it can be hard to distinguish these areas because there is no difference in vegetation height, but looking ahead for darker and more tangled low vegetation, you can easily identify these dark green areas and avoid them.

            Boulders on this map are mostly synthetic – concrete slabs that supported transmitter towers and guy wires.  Large “boulders” are quite visible, often 2 meters tall.  But, the small “boulders’ can be as low as barely protruding from the ground and very difficult to see in the prairie vegetation.  They have almost all been mapped due to their historical significance, but they are generally not too useful to an orienteer moving at speed.   Small boulders have only been used for controls when they are by themselves, not clustered near many others.  In those few cases, the control flag is not hidden (even if the boulder were high enough to hide it) and will likely be visible before you notice the “boulder” itself.
