Each participant is equipped with a rope. On a start command, the first runner in the group runs to the wall bars and attaches their skipping rope there (marked with a ribbon). He then runs back to the group and triggers the next runner (e.g. handshake after running behind the group). This runner then attaches his rope to that of the person in front of him. Which group is the first to attach all the ropes together? At the end of the relay, the sports director checks the tensile strength of the knotted ropes.
