Abstract
An improved above ground landing pit particularly suitable for pole vaulting events is disclosed wherein the frontal portion of the pit includes an opening which surrounds the plant box having an angularly inclined back wall to accommodate the substantial flexure of the vaulting pole during the vault. The sidewalls of the pit are additionally provided with a tapered recess adjacent the lower edge thereof which permits the upper portion of each sidewall to extend in a cantilevered manner over the respective post standard thereby preventing injury to the athlete. Further, the present invention discloses a unique post standard which is exclusively anchored in position by the weight of the pit yet permits the post to be selectively positioned relative the length of the pit.
