The Zirk Swim Cup, an international swimming competition, commenced with a historic moment as the women's 1500-meter freestyle Estonian record, which stood for nearly 43 years, was shattered. Kirke Mõtsnik achieved this remarkable feat by breaking Aivi Liivi's long-standing record from December 1983. Kommenting on her victory, Mõtsnik expressed disbelief at her achievement, attributing it to extensive training and exertion, as she surpassed the previous record by a significant 1.48 seconds.

In addition to the record-breaking performance, the event showcased high-quality swimming with other notable results, including a remarkable time from Czech Olympic swimmer Jan Cejka in the men's 100-meter backstroke. Cejka's display of skill and speed brought attention to the competition's caliber, emphasizing the significance of athletes from different countries competing in Estonia. The organizer of the event, Kregor Zirk, also made headlines by securing two event wins on the opening day, highlighting a strong local presence in the competition.

This competition is not only a platform for setting records but also promotes international sports collaboration and showcases upcoming talents in swimming. The participation of top athletes sets the stage for future events and raises Estonia's profile in the international swimming community, enhancing its reputation as a destination for significant sporting events.
