An International Sprint Orienteering event may
not take place in the underground (e.g.
cellars, underground buildings) or in buildings (indoor). Therefore, just the main level is shown
on a map.
However, important underground passages (e.g.
lighted tunnel, underpass), which
are important for the runners must be shown in a map.
Traffic must be taken into consideration in urban
areas. The organizers are
responsible for the runners safety. They have to do everything, what is reasonable to prevent
accidents (e.g. close roads or
restrict traffic). If this is not possible, the chosen area is not suitable for sprint orienteering.
