Pool temperatures are generally the same (and optimal), swimmers are separated by wave dampening lane lines, no wildlife (sharks, jelly fish, eels, etc.), no adverse currents, and storms\/strong winds rarely come into play. Compare the differences in the recent 10k Olympics: Calm, freshwater rowing basin\/pond in Beijing and London, rough sea in Rio, hot sea in Tokyo, and strong adverse river currents in Paris. As a result, the sport of marathon swimming doesn\u2019t focus on comparative times for these races.<\/p>\n<p>The International Marathon Swimming Hall of Fame (IMSHOF) does, however, track certain types of records, including: Fastest, first-ever, longest\/slowest, youngest\/oldest, and most times\/totals.<\/p>\n<p><strong>Fastest Swim<\/strong><\/p>\n<p><strong>The Island of Capri to Naples, Italy (36 km):<\/strong> In the years 1953-1983, 1986-1992, and 2003-2006, this race was considered a major championship and the top swimmers in the world competed. The overall (male\/female) speed record is held by <a href=\"https:\/\/www.imshof.org\/_files\/ugd\/bd1926_ab9f9077a8cf49f1ace568ed74f661aa.pdf\">Arianna Bridi<\/a>*, Italy, in a time of 6 hours, 4 minutes, 26 seconds.
