Long-distance swimming is practiced in open waters, such as rivers, lakes, open sea, or even pools.
It is divided into four categories according to the distance covered: up to 5 km, up to 15 km, up to 25 km, and over 25 km.
This discipline was contested for the first time in the 2008 Olympic Games in Beijing with the men's and women's 10 km open water marathon.
