Guinness said the 47-year-old Severinsen finished swimming on November 26 in La Paz, Baja California Sur, Mexico.
The previous record of 177 meters was set in 2016 by Carlos Coste.
Severinsen said his record-breaking swim is aimed at raising environmental awareness.
“When the world was hit by Covid-19 almost a year ago, I was looking for a way to show that the pandemic was no excuse to forget our priorities for nature or put our ambitions on hold. Why did I spend time learning and developing as myself? so is his message. “
Severinsen described the distance of 202 meters as “symbolic”.
Severinsen also holds the record for the longest ice swimming with fins and a diving suit and without fins and a diving suit, at 152.4 meters and 76.2 meters, respectively.
He also set a record for 2012 for the longest time held voluntarily, holding his breath for 22 minutes. Since then, this record has been broken at 24 minutes and 3.45 seconds.
