The fastest time to complete six different 10-km (6.2-mile) marathon swims on six continents is 15 days 8 hours 19 minutes, achieved by Jaimie Monahan (USA, b. 11 August 1979) in New York City, New York, USA, on 28 August 2018. Jaimie's first swim started in Cartagena (South America) on 13 August 2018 at 09:40 (14:40 UTC) and her last swim ended in New York City (North America) on 28 August 2018 at 18:59 local time (22:59 UTC). The record was verified by World Open Water Swimming Association (WOWSA).

For the purpose of this record, marathon swim was defined as a non-stop swim in open bodies of water of at least 10 km (6.2 miles) in distance - a distance that, although not universally adopted, is also recognized by the Olympic Committee and FINA.

Adhering to the strict “Channel Swimming Association Rules”, which prohibit any aid to heat retention, such as a wetsuit or neoprene cap, Jaimie wore a standard swimsuit, silicone cap, silicone earplugs, goggles and sun protection (zinc) for each swim.

Below are the details of Jaimie's swims:

South America - 13 August 2018, from Pendales to Corales del Rosario National Park, Cartagena, Colombia, 10.2 km in 5 hours 25 minutes 1 second in 30 - 32.7°C water.

Oceania - 17 August 2018, from Little Bay Beach to Bondi Beach in Sydney, Australia, 10.5 km in 4 hours 11 minutes 12 seconds in 15°C water.

Asia - 20 August 2018, along the length of East Coast Park, Singapore, 10.5 km in 3 hours 27 minutes 13 seconds in 29°C water.

Africa - 24 August 2018, from Al'Mina Ash Sharqiyah Marina in Eastern Harbour to Beau Rivage Jetty, Alexandria, Egypt, 10.5 km in 5 hours 21 minutes in 30°C water.

Europe - 26 August 2018, Lake Geneva/Lac Léman, 13-km Geneva Classic from Lausanne, Switzerland, to Evian-les-Bains, France, in 4 hours 50 minutes in 20°C water.

North America - 28 August 2018, 45.9-km circumnavigation swim around Manhattan Island, New York City, starting and ending at Pier A in 9 hours 43 minutes.

Jaimie, the 2016 and 2017 World Open Water Swimming Woman of the Year, is also the first person, male or female, to complete the Ice Seven Challenge, which requires swimming an ice mile under standard ice swimming rules in Europe, Oceania, Asia, North America, Africa, South America and at any Polar location at 60º south or below or 70º north or above, one of which is a documented Zero Ice Mile.

While juggling a full-time job as a recruiter for Deloitte in New York, Jaimie has won numerous accolades as an open water, ice and winter swimmer. She is a seven-time United States national champion in winter swimming, and an International Marathon Swimming Hall of Fame inductee.
