The little McCaw dives into the water and swims to the other side before leaping out and ditching her swim gear for shoes and a bike helmet.
Her dad is seen helping her clamber onto her pink bike and giving her a push as she scoots off down the drive. Another shot shows her making a return ride to the pool area, with dad jogging behind her.
From here she’s off the bike and pulling on a backpack before sprinting away again.
The video has received more than 4200 likes and plenty of praise from followers since it was posted just three hours ago.
“OMG I love this! Awesome dad ... brilliant parenting duo ... Go family,” wrote one.
Another commented: “That is beyond cute!!! Clearly it’s in her genetics!! Love how she hugs support crew before she starts!!”
Others praised the video as “adorable” and “Great to show her this when she has completed her first one!”
Meanwhile, the proud dad has just completed his own gruelling event, the Kathmandu Coast to Coast at Serpentine Beach, near Kumara Junction, last weekend.
Competing in tandem with Olympic rowing champion Nathan Cohen, the 243km race saw them battle their way across the South Island to the finish line at New Brighton Beach.
