circle drawn with a
radius of 8m.
The arc shall consist of
an at least 70mm wide strip painted
or made of wood or a suitable non-corrodible material like plastic.
The landing
sector shall consist of cinders or grass or other suitable material.
The maximum
overall downward inclination of the landing sector,
in the throwing direction, shall not exceed 1:1000 (0.1%).
Landing
Sector markings:Except for the Javelin Throw, the landing sector marked with white lines 50mm wide at an angle of 34.92° .
Note: The 34.92°
sector may be laid out accurately by making the distance between the two
points on the sector lines 20m from
the centre of the circle 12m ± 0.05m (20m × 0.60m) apart. Thus, for every 1m from the centre
of the circle, the distance
across shall be increased by
0.60m.
In the
Javelin Throw, centre of the circle of which the arc
is part (see Figure (e) TR32). The sector angle is thus 28.96°.
Trials
In the Shot Put, Discus Throw and Hammer Throw, implements shall be thrown from a circle,
and in the Javelin Throw, from a
runway. In the case of trials made from a circle, an athlete shall commence their trial from a stationary position inside the circle. An athlete is allowed to touch the inside of the rim. In the Shot Put, they
are also allowed to touch the inside
of the stop board described in Rule 33.2 of
the Technical Rules.
It
shall be a failure if an athlete in the course of a trial:
after they have stepped into the circle
and begun to make
a throw, touches with any part of their body
the top (or the top inside edge) of the rim or the ground outside the circle;
in the Shot Put,
touches with any part of their body any
part of the stop board other than its inner side (excluding its top edge which is considered to be part of the top);
in the Javelin Throw, touches with any part of their body
the lines which mark the runway or the ground
outside.
for throws made from a circle, if when leaving the circle, the athlete’s first contact with
the top of It shall be a failure if the athlete leaves the circle or runway before the implement has touched the ground, or
the rim or the ground outside
the circle is not completely behind the white line which is drawn
outside the circle running,
theoretically, through the centre of the
circle;
Note: The first
contact with the top of the rim or the ground
outside the circle is considered leaving.
in the case of the Javelin Throw, if, when leaving the runway, the athlete’s first contact with the parallel lines or the ground outside the runway is not
Distance
Measurement
In all throwing events, distances shall be recorded to the nearest 0.01m below the distance measured
if the distance measured is not a whole centimetre.
The measurement of each throw shall be made immediately after each valid trial (or after an immediate oral protest made under Rule 8.5 of the Technical
Rules) from the nearest mark made in contacting the ground when it first
lands by:
the shot, discus and hammer head, to the inside of the circumference of the circle along a
line to the centre of the circle; or
the head of the javelin to the inside edge of the arc, along
a line to the centre of the circle of which the arc is part.
