THROWING EVENTS - General Conditions

Official Implements

1. In all international competitions, the implements used shall comply with IAAF specifications. Only implements which hold a current

valid IAAF certificate of approval may be used.

2. All such implements shall be provided by the Organising Committee for all competitions held under Rule 12.1(a). In these

competitions, competitors are not allowed to use any other implements.

3. No modification shall be made to any implements during the competition. At competitions other than those under Rule 12.1(a),

competitors may use their own implements, provided these are checked and marked as approved by the Organising Committee

before the competition and made available to all competitors.

Personal Safeguards

4. (a)No device of any kind - i.e. the taping of two or more fingers together - which in any way assists a competitor when making

an attempt, shall be allowed. The use of tape on the hand shall not be allowed except in the case of the need to cover an open

cut or wound. However taping of individual fingers is permissible in hammer throwing. The taping should be shown

to the Chief Judge before the event starts.

(b)The use of the gloves is not allowed, except for throwing the hammer. In this case, the gloves shall be smooth on the back

and on the front and the tips of the fingers, other than the thumb, shall be exposed.

(c)In order to obtain a better grip, competitors are permitted to use a suitable substance on their hands only or, additionally on

their gloves, in the case of hammer throwing.

(d)In order to protect the spine from injury, a competitor may wear a belt of leather or other suitable material.

(e)In the Shot a competitor may wear a bandage at the wrist in order to protect it from injury.

Throwing Circle

5. Circles shall be made of band iron, steel or other suitable material, the top of which shall be flush with the ground outside.

The interior of the circle may be constructed of concrete, asphalt or some other firm but not slippery material. The surface of this

interior shall be level and 1.4 - 2.6cm lower than the upper edge of the rim of the circle.

In the Shot, a portable circle meeting with these specifications is permissible.

6. The inside diameter of the circle shall be 2.135m (5mm) in Shot putting and Hammer throwing and 2.50m (5mm) in Discus

throwing. The rim of the circle shall be at least 6mm thick and shall be white. The hammer may be thrown from the discus circle provided the

diameter of this circle is reduced from 2.50m to 2.135m by placing a circular ring inside.

7. A white line 5cm wide shall be drawn from the top of the metal rim extending for at least 75cm on either side of the circle. It may be

painted or made of wood or other suitable material. The rear edge of the white line shall form a prolongation of a theoretical line through

the centre of the circle at right angles to the centre line of the landing sector.

8. A competitor may not spray nor spread any substance in the circle or on his shoes.

Javelin Runway

9. In the javelin event the minimum length of the runway shall be 30m and the maximum 36.5m. Where conditions permit, the minimum

length shall be 33.5m. It shall be marked by two parallel white lines 5cm wide and 4m apart. The throw shall be made from behind an

arc of a circle drawn with a radius of 8m. The arc shall consist of a strip painted or made of wood or metal 7cm wide. It shall be white

and be flush with the ground. Lines shall be drawn from the extremities of the arc at right angles to the parallel lines marking the

runway. These lines shall be white, 75cm long and 7cm wide. The maximum allowance for lateral inclination of the runway shall be

1:100 and the overall inclination in the running direction 1:1000.

Landing sector

10.The landing sector shall consist of cinders or grass or suitable material on which the implement makes an imprint.

11.The maximum allowance for the overall downward inclination of the landing sector, in the throwing direction, shall not exceed

1:1000.

12.a) Except for the javelin throwing, the landing sector shall be marked with white lines 5cm wide at an angle of 40 such that

the inner edge of lines, if extended, would pass through the centre of the circle.

Note: The 40 sector may be laid out accurately by making the

b) In the javelin throwing, the landing sector shall be marked with white lines 5cm wide such that the inner edge of the lines, if

extended, would pass through the two intersections of the inner edges of the arc, and the parallel lines marking the runway and

intersect at the centre of the circle of which the arc is part. The sector is thus about 29.

Trials

13.In the Shot, Discus and Hammer, implements shall be thrown from a circle, and in the Javelin from a runway. In the case of attempts

made from a circle, a competitor shall commence his attempt from a stationary position inside the circle. A competitor is allowed to

touch the inside of the iron band. In the Shot he is also allowed to touch the inside of the stop board described in Rule 188.2.

14.It shall be a foul if the competitor in the course of an attempt:

(a)improperly releases the shot or the javelin,

(b)after he has stepped into the circle and begun to make a throw, touches with any part of his body the top of the iron ring or the

ground outside the circle,

(c)in the Shot, touches with any part of his body the top of the stop board,

(d) in the Javelin, touches with any part of his body or limbs the lines which mark the boundaries of the throwing area or the

ground outside.

15.Provided that, in the course of a trial, the Rules relative to each throwing event have not been infringed, a competitor may interrupt

a trial once started, may lay the implement down inside or outside the circle or runway and may leave them.

When leaving the circle or runway he shall step out as required in paragraph 17 before returning to the circle or runway to begin a

fresh trial.

Note: All the moves permitted by this paragraph shall be included

16.For a valid trial, the shot, the discus, the head of the hammer, or the tip of the javelin shall fall completely within the inner edges of the

landing sector.

17.The competitor shall not leave the circle or runway until the implement has touched the ground.

For throws made from a circle, when leaving the circle, the first contact with the top of the iron band or the ground outside the circle

shall be completely behind the white line which is drawn outside the circle running, theoretically, through the centre of the circle.

In the case of the javelin, when the competitor leaves the runway the first contact with the parallel lines or the ground outside the

runway shall be completely behind the white line of the arc at right angles to the parallel lines.

18.After each throwing, implements shall be carried back to the area next to the circle or runway and never thrown back.

Measurements

19.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.

20.The measurement of each throw shall be made immediately after the attempt:

a) from the nearest mark made by the fall of the shot, discus and hammer's head, to the inside of the circumference of the circle

along a line to the centre of the circle;

b) in the javelin event, from where the tip of the javelin first struck the ground to the inside edge of the arc, along a line to

the centre of the circle of which the arc is part.

Markers

21.A distinctive flag or marker may be provided to mark the best throw of each competitor, in which case it shall be placed along, and

outside, the sector lines. A distinctive flag or marker may also be provided to mark the

existing World Record and, when appropriate, the existing Continental or National Record.
