Entering in the mixed team was the side known as In with a chance.
The team was made up of swimmer Cecilia Crooks (18), Kees Duyvesteyn (20) a cyclist, who had lined up in the Tour of Southland, and runner Georgia Mitchell (18).
Facing up to more than 100 mixed teams, the youngsters knew it would be a tough race.
But they did not realise it would be quite as tough as the side called Celebrity Sports team which was their opposition.
That trio was made up of former Commonwealth Games triathlete Tony Dodds, world No1-ranked paddleboarder Annabel Anderson and former Olympian and world No1-ranked triathlete Andrea Hewitt.
Dodds did the 1.9km swim, Anderson the 90km bike and Hewitt finished with the 21.1km run.
Crooks was neck and neck with Dodds after the swim but it was in the cycling that the younger team really made their mark.
Duyvesteyn rode one of the quickest times of the day and recorded 2hr 9min 34sec for the 90km, which was even quicker than individual winner Braden Currie managed.
That gave Mitchell a huge advantage into the final leg and she carved out the 21.1km in 1hr 37min 57sec to bag the win.
Hewitt also ran hard in just under 1hr 23 min but the trio of Dunedin athletes still won by more than 20min.
Mitchell said it was a thrill to win and even more so to beat some experienced athletes.
