"This is for the ones who have decided they want to do it competitively. All of them [in the squad] started off doing the kids triathlon."
Alysha Donovan and Emma Hutchinson, both 12, are among the 12-strong squad. They started doing the Ray White Allens Kids Triathlon and now compete in national and regional triathlons across the country.
"We'd done school triathlons but that was our first proper triathlon," Miss Donovan said.
The two have been involved in the sport from the age of 7 and said they had known they wanted to do it competitively ever since that early start.
"It's always been one of my favourite things to do and it's one of the main sports [I'm involved with]," Miss Donovan said.
Both girls placed in the Northland Secondary School Triathlon last Saturday - Miss Donovan winning gold and Miss Hutchinson bronze.
Tomorrow's race will act as a warm-up for the girls, who will head to Taupo next weekend to compete in the New Zealand Secondary School Triathlon. They said that through the development squad they had become stronger.
"Some days we do swimming training on Tuesday at 6.30am and Thursdays we do all types - swimming, biking, running and even a mini-triathlon for 30 minutes non-stop and we just keep it going. Or [we do] bike training," Miss Hutchinson said.
-The event is from 9.30am to 1.30pm and runs along Beach Rd. The following will be closed from 8am-2.30pm: 400m southwest of Pah Rd to the intersection of Scott Ln and Beach Rd, Mason St and Cliff St. Also affected by the closure will be Weir Cres, Scott Ln and Hill St.
