1. The group enters the field along the tramline. Only two people need to proceed to the starting point of the first circle (yellow dot), while others stay at the future center point of the whole formation. 40 m per minute is a suitable walking speed (2 meters in 3 seconds, not fast at all). The distance to walk is about 240 m, taking 6 minutes.
