ABSTRACT:
An athlete's landing pit, particularly useful as a landing surface for high jumpers and pole-vaulters, is formed through the side-by-side arrangement of plural foam logs. The individual logs are shaped to provide air spaces within the foam structure to lend resilience to the landing surface. The individual logs of foam are not necessarily glued to each other but may be simply arranged side-by-side and placed within a fabric covering which is used to maintain the arrangement of the logs. The individual logs are therefore easily stored and replaceable individually. In addition, the individual logs within the landing pit structure may be placed at different locations each time the landing pit is constructed in order to avoid excessive wear on any individual log element.
