Whakatane's Sam Clark backed up his pre-race confidence to run away from the field and claim his first Coast to Coast men's title.
Clark, who was second behind four-time champion Braden Currie last year, was the man to beat heading into Saturday's 234km race, which stretches from Kumara Beach on the West Coast to New Brighton Beach in Christchurch.
Clark was joined by 15 leaders after the opening 55km cycle leg but soon made his move.
He was quick to put the hammer down to blast over Goat Pass in under three hours during the 33km mountain run, and began the short cycle and 67km kayak leg with a 23-minute lead.
Clark was a convincing winner in 11 hours 37 minutes, more than 50 minutes ahead of Bob McLachlan, 42, who was tackling the event for the first time in 25 years.
