"I couldn't feel my legs at all and around the turn at Omanu I was thinking, 'I'm in trouble', because I kept collapsing and couldn't feel it. It was only when I picked up my board that I could feel my legs," Cochrane said.
Bryant was rightly proud of his performance, which followed last year's sixth place and included a 5min time penalty.
"That is probably the best race I have done and the most tired I have ever been afterwards. Ben was just a better competitor on the day so he deserves it. This event is awesome. It has got everything and that jump off the rocks makes it that much more exciting," Bryant said.
"I extended the lead when he got cramp. I just went for it, and coming back in he slowly caught me and obviously had that extra bit of strength in him."
Ben Gillies from Piha was third (2:20.47) with Bethlehem College student Hamish Miller taking fourth place (2:20.49).
In the women's race, defending champion Kirsty Wannan from Piha (2:33.20) overcame a tough start to beat clubmate Hannah Williams (2:34.34). "I went out with my own race plan and was confident in the training that I'd done that it was enough to get me over the line," Wannan said. "I definitely learned lots from last year."
Mount Maunganui's Jessica Miller, who had also been training with Cochrane in Queensland, impressed finishing in third place (2:36.46).
