Swimming (sport)
Open-water swimming

Open water swimming is swimming outside a regular pool, usually in a lake, or sometimes ocean. Popularity of the sport has grown in recent years, particularly since the 10 km open water event was added as an Olympic event in 2005, contested for the first time in the 2008 Olympic Games in Beijing.

New recent technology has developed much faster swimsuits. Full body suits have been banned, but swimmers at the very top levels still wear suits that have been lasered together because stitching creates drag. The disadvantage of these suits is that they are often uncomfortable and tight, and can tear easily if not handled carefully.

The largest Ocean Swim's in terms of numbers of participants are in Australia, with the Pier to Pub, Cole Classic and Melbourne Swim Classic all with roughly 5000 swimming participants.
