This system ensures maximum variability with regard to different areas of the installation. The elimination of tripping hazards increases the comfort of use and simplifies maintenance. In order to comply with the regulations of the International Association of Athletics Federations, it is sufficient, where necessary (e.g. in case of a competition) to provide the channel bodies along the inside of the running track with a mobile frame or plastic cover.
