1. A competitor fails if he:

(a)touches the ground beyond the take-off line with any part of his body, whether running up without jumping or in the act of jumping; or

(b)takes off from outside either end of the board, whether beyond or before the extension of the take-off line; or

(c)in the course of landing, touches the ground outside the landing area nearer to the take-off than the nearest break in the landing

area made by the jump; or

(d)after a completed jump, walks back through the landing area;

or

(e)employs any form of somersaulting whilst running up or in the act of jumping.

Note 1: It is not a foul, if the competitor runs outside the white lines marking the runway at any point.

Note 2: It is not a foul, if the competitor walks back through the landing area after having left the landing area in a correct way.

2. Except as shown in 1(b) above, if a competitor takes off before reaching the board it shall not, for that reason, be counted as a

failure.

3. All jumps shall be measured from the nearest break in the landing area made by any part of the body or limbs to the take-off line, or

take-off line extended. The measurement shall be taken perpendicular to the take-off line or its extension.

4. The take-off shall be marked by a board sunk level with the runway and the surface of the landing area. The edge of the board which is

nearer to the landing area shall be called the take-off line. Immediately beyond the take-off line there shall be placed a

plasticine indicator board for the assistance of the Judges. If it is not possible to install the above apparatus, the following

method should be adopted: immediately beyond the take-off line and across the length of it over a width of 10cm the ground shall be

sprinkled with soft earth or sand, at an angle of 30° to the horizontal.

5. The distance between the take-off board and the far end of the landing area shall be at least 10m.

6. The take-off board shall be placed between 1m and 3m from the nearer end of the landing area.

7. Construction. The take-off board shall be rectangular, made of wood or other suitable rigid material and shall measure 1.21m to

1.22m long, 20cm (±2mm) wide and 10cm deep. It shall be white.

8. Plasticine Indicator Board. This shall consist of a rigid board, 10cm (±2mm) wide and 1.21m to 1.22m long made of wood or any other

suitable material. The board shall be mounted in a recess or shelf in the runway, on the side of the take-off board nearer the landing area.

The surface shall rise from the level of the take-off board to a height of 7mm (±1mm). The edges shall either slant at an angle of 30° with

the edge nearer to the runway covered with a plasticine layer along its length 1mm thick  or shall be cut away such that

the recess, when filled with plasticine shall slant at an angle of 30°.  When mounted in this recess, the whole assembly

shall be sufficiently rigid to accept the full force of the athlete's foot. The surface of the board beneath the plasticine shall be of a material

in which the spikes of an athlete's shoe will grip and not skid. The layer of plasticine can be smoothed off by means of a roller or

suitably shaped scraper for the purposes of removing the footprints of the competitors.

9. The landing area shall have a minimum width of 2.75m and a maximum width of 3m. It shall, if possible, be so placed that the

middle of the runway, if extended, would coincide with the middle of the landing area.

Note: When the axis of the runway is not in line with the centre line of the landing area, a tape, or if necessary, two tapes, should be

10.The landing area should be filled with soft damp sand, the top surface of which shall be level with the take-off board.
