Gradient and Drainage for Athletic Rubber Running Track
1. Gradient of Gradients of the 400m Standard Track
For the competition area for Track Events the following maximum gradients shall apply:
- 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.
- 1.0% across the width of the track towards the inside lane. The transverse 1.0% gradient
is primarily to ensure quick drainage of rainwater from the athletic rubber track running surface.
In very dry desert climates it might be appropriate for the track to be flat.
2. Requirement for the Drainage of 400m Standard Track
When completely covered with water and allowed to drain for 20 minutes,
there shall be no area of synthetic athletic rubber running track surface
where the depth of residual water exceeds the texture depth of the surface.

Method
The synthetic surface is flooded with water by any appropriate means and the 20 minutes
is measured from the time the flooding stops. After that time, the surface is examined for
standing water. Locations with standing water above the top of the surface texture of the
synthetic surface are noted on a plan of the facility with the approximate square metres and
the maximum depth of the water, and included in the report.
