Marathon and ice swimmer Jaimie Monahan has become the first person in history to complete a quadruple circumnavigation of Manhattan.

The New Yorker swam four consecutive laps around the island over the weekend, completing the 114-mile effort in 45 hours and 24 minutes.

Monahan finished her first lap in 09:32:30, her second in 12:34:30, her third in 12:49:22 and her fourth in 11:02:38.

Last month she also swam an unprecedented seven times around the island in seven days – a total of 199 miles of swimming.
