Lee Patterson is days away from finishing 'The Long Run'.
She is taking part in the event to honour her dad John Patterson.
John Patterson, from Tiger Signs or Patto as he was known, passed away in March 2018. He had prostate cancer.
Lee has put on her walking shoes to honour her dad.
"This September, I'm taking part in 'The Long Run' organised by the Prostate Cancer Foundation of Australia," she said.
"I've committed to conquering at least 100km walking during September, with my young children and my fitbit, in memory of my dad.
"I hope to raise awareness and funds for other Aussie men and families currently fighting prostate cancer and all that comes with it."
People are encouraged to make a donation to support Lee - here.
Monies will be used to directly support men diagnosed with prostate cancer, to create better awareness of diagnosis and treatment options, and to research ways to minimise the impact of prostate cancer.
"Together, we can help to make sure your fathers, our sons, your brothers, husbands and mates will be here for 'the long run'," Lee said.
