It was also Harriet's good fortune that she was approached by former Ironman New Zealand winner and two-time Olympian Sam Warriner to coach her and in May last year Harriet began her Ironman preparations,
A former World Masters Championship swimmer, Harriet has found training for cycling the greatest challenge, but thanks to the efforts of her coach she is on track to achieve her ambitions.
"Because of Sam's knowledge, I can trust her," says Harriet. "She has such great experience and even with a few hitches along the way (injury and illness), she has remained so positive and calm."
With the strong support of family, Harriet admits training up to 11 sessions six days a week has not been too overwhelming, although she admits also juggling family and work commitments has been demanding.
Yet what does she hope to achieve on the day?
"Sam always says you shouldn't have any expectations for your first Ironman," adds Harriet, 38. "A do have a time in my head, although I don't want to put it out there because I don't know what is going to happen on the day."
So, after years of experiencing Ironman New Zealand in a voluntary capacity has she pictured in her mind that moment when she crosses the finish line in Taupo?
"Oh, yes, is gives me shivers and goose bumps because I have wanted it for so long," she adds.
