Gradients for track and field competitions and throwing competitions competition area.

Track Events

For the competition area for Track Events the following maximum overall gradients shall apply:

- 1:1000 (0.1%) downward, in the direction of running. Should the gradient of the sprint track as part of a Standard Track vary, the inclination is measured in a straight line between start and finish line for each event.

- 1:100 (1.0%) across the width of the track towards the inside lane, unless special circumstances exist which justify World Athletics providing an exemption. The transverse aradient ateralinclinationis primarily to ensure quick drainage of rainwater from the track surface In very dry desert climates, it might be appropriate for the track to be flat. To ensure thatbecause of construction inaccuracies, the gradient does not exceed the maximum allowable, it is strongly advised that the design gradient be made slightly less than 1.0%

Jumping Events

For the competition area for Jumping Events, the following maximum overal gradients shall apply:

- In the last 40m of the runway. 1:1000 (0.1%) downward in the running direction for Long Jump, Triple Jump and Pole Vault. Should the gradient of the competition area as part of a Standard Track vary,the inclination is measured in a straight line for 40m from the take-off line or the back end of the box.

- in the last 15m of the runway,1:167 0.6%downward in the running direction for High Jump along a 15m radius of the 16m wide runway area centred midway between the uprights.(The Rules state that an athlete's approach to the High Jump should be up the inclination.)

- 1:100 (1.0%) across the width of the runway for Long Jump,Triple Jump and Pole Vault unless special circumstances exist which justify World Athletics providing an exemption.

Throwing Events

For the competition area for Throwing Events,the following maximum overall gradients shall apply:

- In the last 20m of the runway, 1:1000(0.1%) downward in the running direction for Javelin Throw.

- 1:100 (1.0%) across the width of the runway for Javelin Throw.

-1:1000 (0.1%) downward in the throwing direction for Shot PutDiscus Throw Javelin Throw and Hammer Throw landing sectors calculated along a straight line through the centre of the circle/ javelin throwing arc to the lowest point in the landing sector at any particular distance

- Circles for Shot PutDiscus Throw and Hammer Throw shall be approximately level.

ARRANGEMENT OF THE FACILITIES

When deciding upon the arrangement of facilities, consideration must be given to the necessary movement of athletes during competition.the routes between ancillary rooms and competition areas should be as short as possible and not interfere with events in progress. Since optimum arrangement is almost impossible for competition, the use of facilities must be well planned to ensure the most practical and safe conduct of the competition.

In the same manner, entrances to and exits from the arena must be planned.One exit must be located immediately after the finish line in order to bring the athletes out of the arena to the Mixed Zone and Post Event Area. Entrances should be placed in the other corners of the arena and,preferably,at the starts of sprint events to facilitate the entry of the athletes to the arena and to accommodate the preparation of the sites for competition.

Provision must also be made for transport of competition equipment and implements. and athletes' gear from start areas to the Post Event Area.

For the Marathon and other events taking place mainly outside the stadium, a suitable connecting passage linking the track with the road course must be provided. The slope of the passage should not be too steep as this will affect the athletes. particularly walkers. The passage should be wide enough to take the mass of athletes at the start of the Marathon and road Race Walk.
