Hawke's Bay teenager Trent Kamper overcame rough conditions to win the annual sea swim marathon in Auckland last Sunday.
The Napier Boys' High School pupil clocked 2h 20m 14s to eclipse an open field of 45 others in the 10km grind in testing conditions along a route taking in St Heliers Bay Beach and around Bean Rock lighthouse.
"It's the first time I've done that distance. The water was really rough and it was really choppy," said the 14-year-old who got help from fellow NBHS pupil Jade Wills paddling alongside him in a kayak.
Wills had the licence to supply food and water but Kamper opted only for some hydration around 5km.
"If he wasn't there, I would have got pretty lost," said the swimmer, who suspected the organisers were going to continue regardless of the conditions when they started at 8am. "I didn't eat anything but Jade was very helpful because the sun was rising when we started and it was hard to see sometimes."
