Great running route if you want to take it easy and pick up the pace. Just be careful with the cobblestones.

and in the middle of nowhere there it is, a beautiful colony of cat shelters that match the "modest" little houses in the Belas golf club complex. As it is a private area, the attack on the forest that is being carried out there goes unnoticed, roads destroyed, others (many) created with new constructions in mind :-(
