Time Allowed for Trials, Rule 180.17

The official responsible shall indicate to an athlete that all is ready for the trial to begin, and the period allowed for this trial shall commence from that moment.

For the Pole Vault, the time shall begin when the crossbar has been adjusted according to the previous wishes of the athlete. No additional time will be allowed for further adjustment. If the time allowed elapses after an athlete has started his trial, that trial should not be disallowed.

If after the time for a trial has begun, an athlete decides not to attempt that trial, it shall be considered a failure once that period allowed for the trial has elapsed.

The following times shall not be exceeded. If the time is exceeded, unless a determination is made under Rule 180.18, the trial shall be recorded as a failure:

 Total # of Athletes     Individual Events    Combined Events
 Competing at the
 Start of the Round
  HJ   PV  Other   HJ   PV  Other
 More than 3   0.5   1.0   0.5   0.5   1.0   0.5
 2 or 3   1.5   2.0   1.0   1.5   2.0   1.0
 1   3.0   5.0    -   2.0   3.0    -
 Consecutive Trials   2.0   3.0   2.0   2.0   3.0   2.0

Note (i): A clock which shows the remaining time allowed for a trial should be visible to an athlete. In addition, an official shall raise and keep raised, a yellow flag, or otherwise indicate, during the final 15 seconds of the time allowed.

Note (ii): In the High Jump and Pole Vault, any change in the time period allowed for a trial, except the time specified for consecutive trials, shall not be applied until the bar is raised to a new height. In the other Field Events, except for the time specified for consecutive trials, the time limit allowed will not change.

Note (iii): When calculating the number of athletes remaining in the competition, this shall include those athletes who could be involved in a jump off for first place.

Note (iv): When only one athlete (who has won the competition) remains in High jump or Pole Vault and is attempting a World Record or other record relevant to the competition, the time limit shall be increased by one minute beyond those set out above.

Comment in IAAF Competition Rule Book:

Whilst the Judges should always use a system which notifies or calls the next athlete who is to take his trial plus the one who is to follow, this is essential when the time allowed for an athlete to take his trial is 30 seconds or one minute. They must also ensure that the competition area is completely ready for the next trial before calling the athlete and then starting the clock. The Judges and the Referee in particular must be fully aware of the current competition environment when deciding when to start the clock or to “time out” and call a failure.

Particular circumstances which should be taken into account are the availability of the runway for an athlete’s trial in High Jump and Javelin Throw (when Track Events are being held simultaneously in the same competition area) and the distance for athletes to walk to and through the cage to reach the circle to take their trial in Discus Throw and Hammer Throw.

To be clear, the time limit will not change in the final round of any horizontal Field Event, once only 2 or 3 athletes remain to take their trials. The 1 minute time limit only applies when a horizontal Field Event has only 2 or 3 athletes on the original start list (except for the very first trial of each athlete).

Throwing Events, Rule 187.1 (b) (NOTE) - New Rule

NOTE: It will not be considered a failure if the touch is made without providing any propulsion and occurs during any first rotation at a point completely behind the white line which is drawn outside the circle running, theoretically, through the center of the circle.

The addition of the Note applies to rotational techniques used by athletes in throwing events. It should be interpreted that any "incidental" touch of the top of the rim or the ground outside in respect of the back half of the circle during the first rotation should not of itself be regarded as a failure. However, it is clear that any technique which thereby obtains an advantage through leverage or propulsion would constitute a failure.
