Sliding runway for sports like skiing, sledging and similar. The runway is made of structural elements (1) substantially transversally molded of low cost synthetic material. Each element must be provided with a fitting (4) made of a material of better performance, so as to last longer or to present a better sliding coefficient etc... Some of the elements (4) have a relief and, as they are interchangeable, it is possible to obtain different runways or different segments of a same runway, according to its lay-out.
