The 50th annual Waikiki Roughwater Swim lived up to its name on Monday.

About 1,000 swimmers signed up for the 2.4 mile open water race. Strong currents were moving against competitors as they swam from Kaimana Beach to the Hilton Hawaiian Village on the opposite side of Waikiki. KITV4 was there as Australia's Ollie Signorini crossed the finish line first. When he got to land, Signorini said he didn't realize he won. 

"When we past the last can, two girls were in front of us, so I just thought I'd gotten too far off course," Signorini explain. "So when I hit the beach, I thought I was out of the top few and turns out I wasn't, I was okay."

Ashley Twichell was right behind Signorini and placed first in the women's division. 

"You could tell just by looking at the bottom when there was rocks or reef, you could tell we weren't moving very fast," Twichell said of the challenging ocean conditions. "So it definitely felt long. It was tough."

Organizers tell us conditions at the 2018 Waikiki Roughwater Swim were much better. The winners clocked in at 45 minutes, 15 minutes faster than this year.
