Peter Bray said he was "ecstatic" after finishing the trip

The team included Nigel Dennis, 50, from Holyhead, Anglesey and Jeff Allen, 43, from Penryn, Cornwall.

Team-leader Pete Bray, 48, from Pembrokeshire, said he was "ecstatic" to be part of the first British team to have completed the trip.

Team member Hadas Feldman, 34, is the first woman to complete the marathon.

The team made the 420-mile trip in 13 days, just three days longer than they had originally thought.

Ex-SAS soldier Pete Bray described the trip as the "ultimate" challenge.

Adventures

The team used the trip to highlight the work of two different charities, Children in Crisis and Tŷ Hafan, a children's hospice near Cardiff.

Teams from the Royal Marines and New Zealand have tried and failed the challenge in the past.

Before the trip Mr Bray said:"To climb Everest would be easier. It will be very tough - that is why it has never been done."

This record-breaking voyage is the latest in a string of adventures for Mr Bray. In 2000 he set out on a solo, unsupported kayak trip from Newfoundland to the UK - but his tiny craft sank, and he was rescued after 33 hours in the freezing Atlantic.

He made a second, successful attempt in 2002 - and became the first person to paddle solo and unsupported across the Atlantic.

He was awarded a Royal Humane Society medal for the rescue of a fellow crew member on board a boat which split in two during a storm last summer - 300 miles from their destination in Falmouth, Cornwall.
