One runner runs in a slalom to the turning point (e.g. colouring stick, marker cone or cone) or to the hall wall and back. On the way back, the runner either also performs a slalom or runs directly to the group to send the next runner onto the course.
Variant:
At the first and last obstacle or at each obstacle (e.g. painting stick, marker cone or cone), perform a complete turn around the slalom marker.
Replacements: Run over a line (with a handshake), through a gate, around the group with a handshake (on the back), crawl through the legs of the next runner, hand over an object, etc.
