A Rules for Foot Orienteering Events - Orienteering USA

C.30.4 The preliminary announcement of the possible postponement should be made at
the latest 2 hours before the beginning of the race, and the announcement of the
new beginning at the latest two hours in advance.
C.30.5 Under exceptional circumstances, when the postponement of a race is out of the
question, a mass start may be used. For example, a significant snowfall in the
hours immediately prior to the race may make it impossible to regroup the tracks
and trails before the race. In order to prevent later competitors from following the
route of earlier competitors in the fresh snow (thereby negating navigating skill),
and in order to assure that later competitors do not ski on significantly faster
tracks than earlier competitors, a mass start may be appropriate.
C.30.6 In the case of poor snow conditions, a preliminary decision on whether to hold the
event must be made by the meet organizer by 6:00 p.m. two evenings prior to the
event. A telephone number must be included in the entry form that competitors
can call that evening to check if the event will be held

C.31.4 Prior investigation of the competition area is forbidden.
C.31.5 Leaders of the event are obliged to bar entrants from competing (but not from
participating in the event) when they are so well acquainted with the terrain that
they would derive substantial advantage over others. In the event of a protest, the
matter is decided by the Jury.
C.31.6 A competitor wishing to retain eligibility shall not seek to obtain an unfair
advantage by communicating with other competitors, team officials, event
officials, journalists, spectators or others before or during the competition.

owners or administrators, officials, journalists, spectators, and others as well as

are considered a part of this rules document. This does not prohibit the use of
medically necessary drugs prescribed by a physician.
