Youth Olympics: 'KiwiRoos' win mixed team triathlon silver

New Zealand has combined forces with Australia to create the 'KiwisRoos', who won silver in the mixed triathlon team event at the 2018 Youth Olympic Games in Buenos Aires on Friday (NZ time).

Kiwi pair Dylan McCullough and Brea Roderick raced alongside Aussie combo Josh Ferris and Charlotte Derbyshire. They crossed the line in 1h 26m 32s, just 20s behind winners Europe 1, which included athletes from Portugal, Holland, Italy and Switzerland.

Europe 3 finished a further 2m 47s back.

The Oceania combination were an outside chance for a medal, after their individual results from earlier in the week saw them ranked sixth heading into the race.

"On paper, they were a lot better than us," McCullough admitted. "We put on our A-game today and it paid off - silver, we're stoked."

The triathlon saw all four athletes complete at 0.3km swim, 6.3km bike ride and a 2.1km run.

Both the New Zealand and Australian Olympic Twitter pages posted the result, congratulating the athletes and celebrating their new name - the KiwiRoos.

"We will always be connected, because of this," Roderick said. "It just feels amazing and you feel so proud of everyone as a team.

"They're such a good group of people, I couldn’t be happier for all of us. It’s really special."  

For Kiwi McCullough, it was the second medal at the event, after his gold in the men's individual triathlon on day two of the Games, with Roderick finishing ninth in the women's race.
