Scottish swimmer sets record between New Zealand islands

Andy Donaldson swam through the night to achieve his latest record-breaking feat

A Scot has set a new world record for the fastest swim across the Cook Strait - the waters between New Zealand's North and South Islands.

Andy Donaldson, 31, swam through the night to complete the 23km route in four hours and 33 minutes.

It was the third leg of seven comprising the Oceans Seven challenge.

The Ayrshire man has already broken the British record for swimming the English Channel and became the first Scottish male to swim from Ireland to Scotland.

He waited over three weeks for the right wind conditions before setting off from Wellington, at the bottom of New Zealand's North Island, just before midnight on 7 March.

The body of water across to Picton, at the top of the country's South Island, is known for its strong tides.

Wearing just "a pair of Speedos, goggles and a swim cap" - competitors are not allowed to use wetsuits - Donaldson said it was "pretty surreal" swimming under the moon and stars.

He beat the previous record, which had stood for 15 years, by just four minutes.

"For something of that distance to come down to the wire like that made for an exciting and nerve-wracking finish, but fortunately I got there under the old time," he told the BBC's Good Morning Scotland programme.

"The Cook Strait is a challenge in itself. It's very windy down there - as anybody who has been to Wellington will know - and the weather in that channel almost acts like a wind tunnel.

"It is also very tidal and the temperatures were probably down to similar to back home in Scotland - around 14C.

"It was a long time to be exposed to that cold water, but fortunately I survived with all my limbs intact.

"Swimming through the hours of darkness was a nerve-wracking experience, but we couldn't have asked for a better swim."

Andy, a proud Scot, won national titles in the pool before switching to open water events

The Oceans Seven features the toughest and most iconic channel swims in the world, ranging in distance from 20km to 44km.

Andy, originally from West Kilbride, North Ayrshire, is aiming to complete all seven legs of the epic 200km challenge in the space of a year, something never achieved before.

Last August he swam across the English Channel in eight hours to break a 25-year-old British record, before completing the North Channel from Northern Ireland to Portpatrick in September in nine hours.

His next swim, sometime during a 10-day window in April, will see him tackle the 42km Molokai Channel in Hawaii.

Andy, who began swimming at a pool in Largs, said he practised a lot of cold water acclimatisation before his latest challenge.

Donaldson's time was only around 80 minutes longer than it takes to travel between the Islands by ferry

"That is one of the big challenges with all these swims," he said. "It was the same with the English Channel. They have very traditional rules, based on the first guy who did it, so I put wool fat - lanolin - on my body and lathered up beforehand.

"The best preparation is to just go in for a cold swim and really acclimatise to the conditions. If you are not ready, it can really affect you and almost shut your body down."

As an ex-professional pool swimmer, Andy won national titles at 200m freestyle but switched to open-water swimming after moving to Perth, Australia, 10 years ago.

Back on dry land, Andy is planning the next leg of his Oceans Seven challenge in Hawaii

Inspired by his Scottish grandfather, who "really struggled with depression", Andy is raising funds for Australian-based mental health charity the Black Dog Institute.

"Hopefully the next swim in Hawaii will be a bit warmer and we can get across safely. They all have their own unique challenges," he added.

"We are just giving it our best, raising money for mental health - that's the purpose behind all this."
