The distance is measured from the rear of the designated take-off area to the nearest landing mark in the pit. From the front of the take-off area to the nearest pit landing spot Take the measurement perpendicular to the take-off line or its extension. The tape's zero end is put where the athlete lands. The other end is marked with a unit length.
For example, if the distance from the back of the take-off area to the nearest pit is 20 feet (6 m), then the triple jump distance is 20 feet (6 m).
The rule is that the mark must be flat and free-standing. It cannot be part of the takeoff platform or track. A vertical obstruction such as a light standard can be used if it is not lower than 10 feet (3 m). If the obstruction is lower than 10 feet (3 m), then it is illegal for an athlete to clear it. They must skip over the obstruction.
A legal mark must be within the viewing range of the judges' boxes. If not, they should be placed there so that they can be seen by the athletes.
An auxiliary line is drawn at 12 feet 6 inches (3.9 m) from the edge of the block. An attempt below this line does not qualify for the event.
To measure the distance accurately, have a friend hold up a marker at the desired point during the take-off.
According to NBColympics.com, "the distance is calculated along the curve of the landing hill from the take-off position to the exact location when the jumper's feet contact the landing slope." The farther back a jump goes, the more points it is worth.
The first Olympic ski jumping competition was held in 1952 at Oslo Holmenkollen. There were three different distances for men: 150, 200, and 250 meters. For women, the only distance available was 105 meters because snow conditions prevented longer jumps.
In 1964, the maximum height allowed for men was set at 90 meters, and for women at 70 meters. These limits were later increased to 95 meters (for men) and 85 meters (for women).
Modern ski jumping was invented in St Antonia by an Austrian named Fritz Schilcher. He called his new sport "Eisbärenschlagen" which means "ice bear slashes". The first official international ski jumping competition was held in 1973 at Val di Fiemme, Italy. There were still three different distances for men: 100, 150, and 200 meters. For women, the only distance available was 75 meters because snow conditions prevented longer jumps.
In 1980, the maximum height allowed for men was raised to 110 meters, and for women to 90 meters.
The distance travelled is calculated from the edge of the take-off board to the depression in the sand nearest to the take-off board (formed by any portion of the athlete's body when landing). After the long jumper walks onto the runway, the full leap must be completed in one minute. If an athlete takes longer than one minute to complete their jump, then they will be disqualified.
The rule was introduced in 1999 by IAAF President Haile Gomes at a meeting in Athens to even out the advantage that European athletes had over their American counterparts. Before this change, American athletes were allowed to leave the take-off board before fully completing their jump because it took them less time to reach the end of the runway. This discrepancy created a need for change.
There are two ways to achieve a long jump: with or without wind assistance. With wind assistance, the long jumper uses a flag or fan to create a wind tunnel effect that increases the distance of the jump. Without wind assistance, the long jumper uses only their body strength to propel themselves into the air.
To compete in the long jump event, an athlete must first qualify by making either the automatic qualifying mark or the maximum permitted number of attempts. The automatic qualifying mark is 20 feet (6 m) if the athlete is male or 18 feet (5 m) if the athlete is female.
