Olympic champion Emma Snowsill held off a gutsy challenge from compatriot and training partner Emma Moffatt to win the opening leg of the inaugural triathlon world championship series in South Korea.
Three-time world champion Snowsill (2 hours 2 minutes and 43 seconds) chased down before shaking off Beijing bronze medallist Moffatt in the final kilometre with Japan's Juri Ide finishing third.
Whangarei's Sam Warriner was the best of the Kiwis in eighth place. Wanaka's Nicky Samuels was 19th, Debbie Tanner (Auckland) 23rd andAndrea Hewitt (Christchurch) well back in 39th.
It was another display of the 27-year-old Snowsill's durability to claim victory after breaking a rib in the surf earlier in the year.
The men race on Sunday.
For the inaugural year, the series consists of eight World Championship events, including grand final to be staged on Australia's Gold Coast in September.
