It sounds like an exhausting week, but Chapman feeds off the hard work and has sorted out her time management skills so her training can fit around sleep and study.
"I prefer training in the mornings, because then it's over and done with for the day and then I go off to school," she says.
The bulk of her training is done at Pukekohe's Rec Centre, though the pool is just 25m. There she comes under the watchful eye of PSC coach Sue Cheyne.
"Abi is one of the most motivated individuals you could hope to meet," says Cheyne. "She has all her goals in place and she just works really hard."
Chapman was Counties Manukau's top performer at the champs, and her times and feats there give cause to wonder how far she could go in swimming.
Cheyne feels, at the current rate of improvement and if she stays dedicated, then the 2018 Commonwealth Games on the Gold Coast is a realistic goal.
This week, Chapman is on an Outward Bound course. She was chosen, as one of just 14 swimmers out of around 700, by Swimming New Zealand. Those 14 have been identified as having "long-term potential" in the sport. Chapman might have a week off and then it's back to rising at 5am, hitting the pool at 5.30am and dreaming of winning. Endurance training will be the focus over winter in the lead-up to the national secondary schools and short-course championships in Wellington.
Chapman draws inspiration from New Zealand's top female swimmer, Lauren Boyle, also a freestyler. They have crossed each other's paths.
"I do look up to Lauren. At opens, we swam against the Olympians and got to watch her and how she prepares."
Chapman works on her weaker strokes - breast stroke is not her forte - and this obviously helps with her individual medley.
She showed she is made of the right stuff by cleaning up at the Pukekohe High School swimming sports ... with a broken thumb. Forgetting the pain, she broke three intermediate records.
But she is not the only talented swimmer from the college. Mackenzie Lambert and Rebecca Cheyne also won medals at the champs and have joined Chapman in being selected for the SNZ high performance camp.
