It is a NoLimits track file in a zipped folder with a help document and statistics document also with it. If you are unfamiliar with downloading custom tracks, click the link below and choose "Save As" when prompted. Save the zip folder to the desktop, open it by double-clicking, and read the help document for the rest of the instructions. (It's really quite easy. ) You can download it here:
