A Scottish-Australian marathon swimmer believes he has set a new record for swimming around Manhattan Island in New York.
Andy Donaldson achieved the feat in five hours, 41 minutes and 48 seconds – with the new record pending ratification.
The 33-year-old completed the 45.9km circumnavigation on Thursday, beating the previous record holder Oliver Wilkinson by two minutes.
Mr Wilkinson set the previous record, which in in 2011.
Mr Donaldson, who grew up in West Kilbride, North Ayrshire, started the challenge at 2am local time.
The swim is traditionally completed in a counter-clockwise direction and travels through the East, Harlem and Hudson rivers.
The full loop takes in New York’s impressive skyline, which includes the One World Trade Center and the Empire State Building, with swimmers also passing under a number of the city’s world-famous bridges, including the Brooklyn and Manhattan bridges.

Navigating currents as strong as four knots, Mr Donaldson relied on the support of an experienced team.
He said their precision was integral to his success as he reached a maximum speed of 12kph.
Mr Donaldson said: “This was one of my toughest challenges yet, both physically and mentally.
“With the three rivers’ tides impacting the swim, we had to time everything perfectly for a shot at the record.
“I’ve been struggling with illness leading up to the event, so it was really tough out there.”
