Wanaka's Braden Currie has won the one-day race in the multisport event, defending the title he won last year.
After leaving the West Coast's Kumara Beach at 6am on Saturday, Currie took 11 hours and 18 mins to reach the finish line in the Christchurch suburb of Sumner.
Five time winner Rich Ussher was second with a time of 11 hours and 39 minutes while Glen Currie was third in 11 hours and 57 minutes.
