Athletic track with post-tensioned concrete slab

An athletic track comprising

• a resilient surface, and
• a post-tensioned concrete slab supporting the resilient surface, the concrete slab having
• a uniform lower surface with substantially no footings protruding therefrom,
• at least two opposed generally rectangular side areas, each side area having
• an inner edge and an outer edge,
• a first set of spaced apart cables substantially parallel to said inner and outer edges of said rectangular areas, and
• a second set of spaced apart, substantially parallel cables, cables of said second set of cables intersecting cables of said second set of cables at a non-perpendicular angle and
• at least two opposed generally semi-circular end areas connecting the side areas, each end area having a curved inner edge and a curved outer edge, each of said semi-circular end area comprising at least two arched segments, said segments being symmetrical about a line separating said segments and having a pour strip connecting said segments at said line.
