Guinness said 47-year-old Severinsen completed swimming on Nov. 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 swimming was aimed at raising environmental awareness.
“When Covid-19 was hit by the world almost a year ago, I was looking for a way to show that the pandemic was not an excuse to forget our priorities for nature or put our ambitions on hold. On the contrary. This is for what I have spent time training and developing both me and my message “.
Severinsen described the 202-meter distance as “symbolic”.
Severinsen also holds the record for longest distance swimming under ice with fins and diving suit, and without fins and diving suit, at 152.4 and 76.2 meters, respectively.
He also set a 2012 record for the longest timed breathing that was voluntarily maintained, holding the breath for 22 minutes. This record has been broken since then and stands at 24 minutes and 3.45 seconds.
