LongSwimsDB was developed by Evan Morrison.

The database covers traditional, unassisted, documented open-water swims of 10 km or longer - both solo and races.

It aims to:

  • compile a structured and accurate historical record of the world's marathon swims and swimmers
  • develop insights about the sport through data analysis and visualisation
