 The first 300 Club outside of Antarctica was established on January 30, 2019 near Minneapolis, Minnesota during a polar vortex.With an outside temperature of −27 °F (−33 °C), three men heated their backyard sauna to 280 °F (138 °C) and sat inside for 10 minutes.Upon exiting the sauna, they sprinted around a flagpole planted in honor of the South Pole tradition, and took a brief roll in the snow before returning to the sauna.
