Freediving endurance 4 × 50 m, women

What to remember

In Kuwait on May 11, 2023, Italy's Chiara Zaffaroni clocked 1 min 33.860 s in endurance, a women's world record recognised by CMAS.

The event is coded END4x50. Unlike depth or distance disciplines, it is expressed as a time, down to the thousandth of a second.

Like all freediving, it relies on holding one's breath with no apparatus at all, the opposite of scuba diving, where the diver breathes from a tank.
