Czech Republic Sets New Guinness World Record for Largest Polar Bear Dip.
The Czech Republic has made history, setting a new Guinness World Record for the largest polar bear dip with 2,461 brave participants who plunged into the icy waters of Most Lake.
This monumental achievement surpasses the previous record of 1,799 participants set in Mielno, Poland, in 2015.
The Cold Challenge
Participants faced water temperatures of just 3.5°C (38.2°F), adding an extra layer of difficulty to this already extreme challenge.
To meet the rigorous criteria established by Guinness World Records, each swimmer was required to wear a bathing suit, submerge at least to waist depth, and stay in the water for a minimum of one minute.
