Event Chief – Throws

The Event Chief, sometimes called the Chief Judge or the Big Kahuna, has to take all the tough calls for both jumping (Long and Triple Jump) and throwing events (Shot Put, Discus and Javelin).

Being an Event Chief is not a huge commitment of time and really benefits the efficiency and enjoyment of the event for the athlete. Typically there are two field events requiring an Event Chief per Age Group each week. The role of Chief is best shared between volunteers.

The Chief looks on at the Shot Put assessing that:

  • The shot shall touch or be in close proximity of the neck or the chin and the hand shall not be dropped below this position during the action of putting.
  • The shot shall be put from the shoulder, shall not be taken behind the line of the shoulders in a forward direction
  • Shall put with one hand only with a forward movement.
  • A competitor may leave the circle (form the rear only) by placing the shot put on the ground within the circle, then re‐enter and recommence the throw again.
  • A competitor may enter the circle from any direction
  • Must leave the circle so their first contact with the ground outside the circle is behind the centre line.
  • A competitor leaving the circle in front of this line. Foul.
  • Once the competitor has begun to make a throw, the ground outside the circle and the top of the stop board must not be touched. Foul.
  • Land entirely within the sector tapes and the shot can’t touch the sector tape. Foul.
  • The measurement is taken from where the shot first hits the ground

The Chief looks on at the Discus assessing that:

  • All are fair throws including a single handed under arm throw, a bowling action over the head and a double handed throw.
  • Athlete touches with any part of their body, the ground outside the circle or the top edge of the iron band, after they have stepped into the circle and begun to make a throw, it is a foul.
  • The athlete must be in a stationary position in the circle before they throw.
  • An athlete may leave the circle (from the rear part of the circle), if after coming to a stationary state, place the discus on the ground within the circle.
  • The athlete must not leave the circle until the discus has landed.
  • An athlete may enter the circle from any direction.
  • An athlete leaving the circle in front of the centre line has fouled.

The Chief looks on at the Javelin assessing that:

  • The Javelin must be held at the grip.
  • It must be thrown over the shoulder or upper arm. It is a foul throw if this is not adhered to. It must not be thrown with a slinging or hurling action.
  • The athlete must not turn their back to the throwing area at any time during the run‐up.
  • Not any part of body is allowed to touch the throwing foul line or go over the foul line or touch the ground.
  • It is not a foul if the end of the javelin touches the ground during the run‐up
  • After the throw they must leave the run‐ up from behind the curved foul throw line and the winged marks on either side. The athlete must not leave the run‐up area before the Javelin has hit the ground.
  • The javelin must strike with the tip of the metal head first. It does not have to stick into the ground or leave a mark.
  • The javelin must land within the marked sector. On the sector line or outside the sector is a foul.
  • If the javelin skids out or flips over the sector line the throw is valid.
  • The measurement is taken from where the javelin first strikes the ground with the tip of the metal head.

The Chief should be located at the shot/discus circle or Javelin run-up, standing at the relevant side for judging right hand and left hand throws. Raise a White Flag for a Fair throw or a Red Flag for a Foul throw.


If the Event Chief is not an accredited Official recognised by the Club, they cannot verify a record has been broken. The Event Chief and the Age Manager should notify the Parent or the Athlete at the beginning of the event so that they can ensure a qualified Official is present to potentially verify any broken record that may take place.

A record in a throwing event (Shot Put, Discus or Javelin) cannot be verified post throw. There are too many variables at play to make this possible without the presence of an accredited Official.

A record in a jumping event (High Jump, Long Jump or Triple Jump) can be verified post jump. The Event however must be stopped so an accredited Official can check the height of the bar, the footprint on the board and the landing marks in the Pit. The Event Chief may be called upon to ascertain other relevant details with respect to the jump as per the Club Records Guidelines.
