A Rules for Foot Orienteering Events - Orienteering USA

B.11 Eligibility
B.11.1 General Eligibility
B.11.1.1 Any person desiring to compete is eligible except as set forth below or in
special cases designated by the Executive Committee.
B.11.1.2 Participation is open to all persons whether or not they are eligible for
placings, provided that those not eligible for placings do not interfere with or
disqualify eligible competitors. All other rules must be followed.
B.11.2 Championship Eligibility
B.11.2.1 Each member of the team must be a member of Orienteering USA.
B.11.2.2 No member of the team may compete in the same calendar year for the same
category of championship in any other national championships.
B.12 Entries
B.12.1 A team shall consist of two, three, four or five members.
B.12.2 A team that has a member less than fourteen years of age shall also have a
member eighteen years of age or over.
B.12.3 Competition placing may be awarded in several categories based on the age and
gender composition of teams. Each team shall be deemed to be entered for all
categories of the competition for which it is eligible.
B.13 Maps
B.13.1 Maps for a Rogaine may be specifically produced for the event, or may be
modifications of an existing (typically USGS) map with the addition of magnetic
north lines, possibly additions to reflect changes in trails, roads, out-of-bounds
areas, etc.
B.13.2 Usually the scale of map should be between 1:24,000 and 1:63,360. Map scale
must be announced to competitors well in advance of the event, preferably on the
publicity announcements.
B.13.3 The mapped area needed for a 24-hour Rogaine is typically 150 square kilometers
or greater, with an optimal route choice requiring somewhat over 100 km to reach
all control locations. The actual area of terrain in use might be somewhat smaller,
but it is undesirable for safety reasons to place controls right at the edge of the
mapped area, as going off map may be harder for recovery than in a shorter
orienteering event.
B.13.4 The map determines the suitability of control sites--the topographic information is
usually much less detailed than on an orienteering map, and the control sites are
necessarily placed on coarser features.
