Abstract
A resilient edge adapter is provided for defining an edge of a drainable athletic playing surface formed of a moldable material. The edge adapter includes a base portion for cooperably engaging an upper portion of a drainage channel and an upstanding portion extending upwardly from the base portion for restraining the moldable material when applied adjacent to the drainage channel, thereby defining an edge of the athletic playing surface. The upstanding portion may be formed of a resilient and elastically deformable material and the base portion may include an elongate continuous plug portion to cooperably engage a corresponding slot defined in the upper edge of the channel. An edge adapter is also provided which has a pair of upstanding portions extending upwardly from a base portion for forming a running track surface over both opposed edges of a grate. Associated methods for forming athletic playing surfaces are also provided.
