A transformable obstacle assembly is described. Embodiments of the transformable obstacle assembly include a dual rail structure and a pair of support structures. Typically, the dual rail structure can include a first rail, a second rail, a plurality of ribs, and a pair of panels. The plurality of ribs can be implemented to couple the first rail to the second rail. To elevate the dual rail structure of the ground, the pair of support structures can be coupled to opposite ends of the dual rail structure. In one embodiment, a height of the support structures can be altered to raise and lower the dual rail structure. Typically, the dual rail structure can be implemented in either a horizontal orientation or a vertical orientation.
