Breaking line in the 400 Mts track for 8oomts Event

Introduction: Breaking Line in middle and long distance events( for example the 800M) the breakline is the point at which runner may cross from their initial lane to the inside lane. Generally, the breakline is after first turn ( in the 800m its 100 into the race.)

The exit from the first bend is marked distinctively with a 0.05m wide line (breakline) across the track to indicate when the athletes can break from their lanes.

Ø  In order to confirm that the camera is correctly aligned and to facilitate the reading of the photo finish image, the intersection of the lane lines and the finish line shall be coloured black in a suitable design.

 

Ø   Any such design must be solely confined to the intersection, for no more than 0.02m beyond, and not be extended before, the leading edge of the finish line. Similar black marks may be placed on each side of an appropriate lane line and the finish line to further facilitate reading.

 

STARTING POINT

v  The essential requirement for all start lines, straight, staggered or curved, is that the distance for every athlete, when taking the shortest permitted route, shall be the same and not less than the stipulated distance, i.e. no negative tolerance.

v  All race distances are measured along the measurement line (0.30m outward from the inside of the track for lane 1 or 0.20m from the inside lane of an outer start) in a clockwise direction (back from the finish line), from the edge of the finish line nearer to the start to the edge of the start line farther from the finish.

Table 2.2.1.6a - Staggered start data for the 400m

Standard Track

(In meter, measured on the running line)

Ø  For races of 800m or less, each athlete shall have a separate lane at the start.

Ø   Races of up to and including 400m shall be run entirely in lanes. The data for staggered starts for 400m Standard Track (constant lane width of 1.22m) are listed in Table 2.2.1.6a.

Ø  Races of 800m shall start and continue in lanes until the end of the first bend. (Figure 2.2.1.6c and Table 2.2.1.6b).

Ø  By the Rules, a curved start line for the 800m is an allowable option for international matches when the countries agree not to use lanes and it coincides with the 2000m and 10,000m start line(s).

Ø  The exit from the first bend shall be marked distinctively with a 0.05m wide line (breakline) across all lanes other than lane 1 to indicate where the athletes can break from their lanes. (Figure 2.2.1.6c).

Ø  To assist athletes identify the breakline, small cones or prisms (0.05m × 0.05m) and no more than 0.15m high preferably of a different colour from the breakline and the lane lines shall be placed on the lane lines immediately before the intersection of each lane and the breakline.
