Preparations for this project lasted over 6 months. Not only the inhabitants of the town, commune and Słupca poviat helped in breaking the record, but also those who visit Słupca from time to time. Folk groups from outside the region also appeared on the stadium turf. They were all dressed in stylized, historic clothes. Even the date was not accidental. The record was broken on the International Dance Day, and the 100th anniversary of independence was celebrated at the same time.

Słupczanie waited for the jury's decision for almost a year. Finally, the longed-for information came that the record was recognized and entered into the Guinness Book of Books. This meant that no one in the world had ever danced a polonaise in such great numbers.
