The 22-year-old Scarborough resident said he felt compelled to help the cancer charity after seeing how much they are relied upon first hand.
‘They help young kids with cancer, anyone who’s helping people in that situation deserve all the publicity in the world,’ Harris said.
‘I thought it would be a good thing to do to raise some money and a bit of awareness because they’re not a massive charity so anything you can do to help is really appreciated.’
The opening batsman for the Alcohol Think Again Western Warriors said Red Kite had helped his sister with money for fuel and bills.
‘It was pretty tough initially; Siena was only 18 months old when she got it,’ he said.
‘The first six or seven months were really tough.
‘My sister doesn’t live close so it’s a long drive to Princess Margaret Hospital.
‘It’s hard work with the parents staying in the hospital for days on end,’ he said.
Harris said his sister was shocked when he told her he would be attempting his first half-marathon for charity.
‘She was really happy, she said she was pretty overwhelmed with it all,’ he said.
Harris has raised more than $2000 for Red Kite ahead of the run.
