Each has a single direction of travel. For example, if your 75-yard lanes run north and south, you begin at the south end of one and move north. Then turn around and travel the other lane. The direction of travel and the order of the targets is up to you; the main point is to have a variety of shots, and ensure that all shooters start and end at the same spot, for safety’s sake. Another safety consideration: ensure that arrows that miss targets land in a safe zone.
In my example, each lane should accommodate two of the larger targets set up for shots of at least 20 yards. In between each large target, place a small-game target with the target side facing the sides of the lanes.
