She said the role she played with the up-and-coming talent was that of preparation.
"I've been coaching them throughout the year and this week is to say, 'Here are the other little skills I can add', so when [New Zealand athletes] go to compete with the rest of the world we're able to. I'm building up those skills, so, if they get the opportunity to be involved, they've got the skills to do it. It's a professional centre [TriNZ] so if they want to take them on you know they're ready to go."
Warriner said that the ITU World Triathlon Series race courses had changed in recent years, which meant specific skills were required for certain parts of the race - like acceleration out of tight corners on winding bike tracks.
To simulate such bike legs, Warriner took the squad to KartSport Whangarei's newly lengthened track to get used to riding in a group in tight spaces and learning to accelerate out of corners.
Sweat7's training squad includes three national champions - Jaimee Leader, Brad Cullen and Anna Wilkinson - as well as three locals, in the form of Louis Poot, Ashlee Greenhalgh and Aaron Greenhalgh.
One of the main purposes of Warriner hosting the squad this week was to ready six of them for Junior Olympic qualifiers this weekend.
As for Warriner herself, she's getting geared up to crack back into competition in the New Year.
"I want to come back and hit the New Zealand season fit and strong. I didn't want to come back too soon," she said after becoming a mother last year.
Next up for the Northland legend was the Tauranga Half Ironman in January.
