The first participant in the group runs (alone) to the turnaround, slips through a tyre there and runs back to the group. Now the first participant runs with the second participant (holding hands) to the turning point, where they have to slip through the tyre again. The hands must not be released. This scenario is repeated until the entire group has slipped through the hoop (together with constant hand grasping). After this round, the first participant (who has travelled the longest so far) is allowed to disengage and the remaining group members continue the exercise. Finally, only the participant who was the last to join the group runs. At the end, all participants in the group have completed the same number of runs. Which group was the first to complete the task?
