ABSTRACT:
A variable stackable ramp system for forming ramp assemblies for providing challenging obstacle courses including ones for aerial lift for sport jumping with skateboards, inline skates, bicycles and the like. The ramp system includes ramp modules of at least two different configurations with one being an inclined ramp module having an inclined upper riding or support surface and a straight ramp module having a generally horizontal straight upper riding or support surface. The ramp modules are adapted to be interconnected horizontally and vertically in a variety of orientations to provide ramp assemblies of selectively different overall configurations.
