Abstract
A deformable base having top and peripheral walls and resiliently deformable interior ribs is formed with a recess in the interior central crown region, the recess being defined by a central web to which a mounting plate is removably attached. The plate is elevated above the ground-engaging parts of the base as a result of which the central web and plate can be downwardly depressed when vertical impact forces caused by a runner contacting the crown region are encountered. This downward depression together with the resiliency of the ribs provides a more uniform absorption of vertical impact forces across the entire top surface of the base thereby eliminating hard and soft areas likely to cause injury.
