I ride this MTB route myself very regularly. You can alternate by, for example, starting from a different parking lot, so that the different parts are more at the beginning or more at the end of your lap. You can also choose whether or not, or half of the extra loop, which, in addition to a beautiful winding single track, also has various TTFs (technical trail features). Not very difficult, but you can choose to bypass them; So-called "chicken runs" have been created for this purpose. In the summer you could even choose to park at the swimming pond so that you can take a refreshing dip after your round.
What is also very nice is that the builders have given the various pieces names.
