Taradale High School dominated the podium at one of the most gruelling multisport events in the country.
Three teams took the top three spots in the schools two day tandem section at the weekend's Coast to Coast.
The eight senior students completed the 243km course made up of 33km running, 140km biking and 70km kayaking.
Zayne Jennings, 17, and Matt Durrant, 16, were the first to cross the line in 15 hours and 52 minutes in the schools tandem section and 12th in the men's pair overall.
"After training for so long we still weren't sure we could complete such an event, let alone a podium finish," Matt said.
