Abstract: An interchangeable/adjustable hurdle component assembly made of a collection of interchangeable parts. The assembly has a plurality of leg support pairs of varying lengths which can be utilized as vertical leg supports or horizontal leg supports. One leg support pair is utilized as a first and second vertical leg support, and one leg support pair is utilized as a first and second horizontal leg support. The first vertical leg support is connected to a first tee and to a first elbow, and the second vertical leg support is connected to a second tee and second elbow. The vertical leg supports determine the height of the hurdle. The first horizontal leg support is connected to the first tee and the second horizontal leg support is connected to the second tee to provide support to the hurdle assembly. A crossbar connects to the first and second elbows. The component parts are tubular for realizing snap-fit connections. Both tees of the assembly are identical and interchangeable as are both elbows.
