摘要

A pole vault pit construction that is formed of multiple resilient foam blocks that are secured in a unitary manner and wherein thee construction is comprised of a front cutout section defining a recess for receiving a pole engager, said front cutout section having an open front end and an inner end, and a contiguous rear landing section. The plurality of foam blocks of the front cutout section include at least one pair of opposed position blocks each having a tapered surface commencing from the upper surface downwardly to the lower surface and in a direction toward the opposed position block so that a cross-section of the recess is essentially trapezoidal. The rear landing section includes at least a center foam block having an uninterrupted tapered surface commencing from the upper surface downwardly to the lower surface and in a direction toward the open front end of the recess.
