  • Patent number: 3961751
    Abstract: A cross-country skiing path has a pair of side-by-side elongated tracks each formed as an upwardly open and longitudinally extending channel in turn each formed of a longitudinal succession of separate track elements that each have a separate web and inside and outside flanges flanking this web. Each inside flange of each element of each row is turned toward an inside flange of a corresponding element of the other row and is provided with an ear extending toward the other row and having a longitudinal length equal to approximately half the overall longitudinal length of the element. Each ear is longitudinally offset from the corresponding ear of the corresponding element of the other row and extends transversely beyond the longitudinal midline of the path. An elongated longitudinally extending connector member, such as a cable, passes through the ears at the midline and interconnects the elements into a chain. Similar connecting members extend through the outside flanges.
