Why do people swim Cook Strait?

People choose to swim Cook Strait for a number of reasons: 

  • Personal
  • Physical
  • Psychological
  • Because “it’s there”

As one of the toughest and most challenging stretches of water in the world, Cook Strait presents the ultimate test for swimmers. There have been swimmers who wanted to be the fastest, the oldest, the youngest and even the slowest. There are those who wanted to cross it several times in one go, to do it in unfavourable conditions and in extreme temperatures. Whatever the reasons, the chance to triumph over this unpredictable stretch of sea remains one of the few real “Everest Challenges” left on the planet.
