"I never in my life thought I could be a triathlete, but with a little bit of grit and determination and commitment to training I got here,"she said.
"A big motivator for me was to normalise exercise to my girls,"she said.
"If their daggy old mum can achieve it, they can too."
"We get people coming in … they can't run further than a few metres, they can barely swim … they might just be able to ride a bike,"she explained.
"These are your friends for life."
"The greatest way for our kids to get moving more is to be role-modelled by the people they love and respect and see everyday."
"You're not 13 anymore ... you can't just run out like you used to."
