Team Seagate members Nathan Fa'avae (42), Sophie Hart (32), Chris Forne (35) and Stu Lynch (28) appeared not greatly affected by their four days and eight hours of almost continuous racing over 540km of mountainous terrain.
Fa'avae told the Otago Daily Times they had managed six hours sleep, in total, during the race, including a few ''little power naps''.
He described the kayak on Lake Wanaka to the finish as awesome.
''It was very, very calm out there and very hot, so we were stopping and swimming and just trying to cool off.''
A tail wind also provided waves for them to surf, and allowed them to race each other.
Fa'avae said it was only at the start of the kayak at 8am yesterday they began to appreciate how big their lead was.
None of the other teams had started the kayak by the time Team Seagate finished the race at 4.32pm.
Team Seagate has won the event three times before and is current adventure racing world champion.
At the finish line, Fa'avae described the course as the most challenging they had struck.
''The weather certainly was a factor as well.
''We were in some pretty exposed places and some bad weather for extended periods.
''We had to rally together a few times and worked pretty hard.
''It's been a great event for us.''
Asked how they kept doing it, Fa'avae said a lot of their success was down to the team structure.
''You need a good navigator ... you do need a strong woman as well ... and I think a lot of it's efficiency - not stopping, and coming up with ways to just keep moving forward on the course, really.
''We are often not going that fast, but we are always moving forward.
''I think that makes a difference.''
Fa'avae said there had been no major navigation issues and physically the team was in ''pretty good shape'', apart from ''a few funky foot things going on from, I guess, being in wet socks for as many days as we were. Nothing too unusual.''
Fa'avae said their next race in the world series was in Spain, and the ''ultimate race'' for the year would be the world championship in Brazil in November.
