A Spiker is only required for a jumping event like the Long Jump and Triple Jump.
Being a Spiker is not a huge commitment of time and really benefits the efficiency and enjoyment of the event for the athlete. Typically there is only one jumping event per Age Group each week.
The Spiker’s role requires waiting for the jump to be completed and the competitor has left the pit, placing the zero-end of the measuring tape, normally on a spike, at the edge of the imprint in the sand nearest the take-off area and wait for the Chief Judge to read the distance at the take-off board/mat.
For the safety of the Spiker, they should stand in a sensible position to avoid possible injury. The best location is to the side of the landing pit, in a sensible position facing the jumper, and concentration is essential.
A Spiker does not require a WWVP Card.
