The Mandurah residents are part of 16-member team Relay In Onesies, for the WA Cancer Council’s Peel-Mandurah Relay for Life at Rushton Park on November 9 to 10.
Teams will walk or run around in relays for 24 hours, signifying cancer never sleeps.
Funds raised before and during the 24-hour event will assist the council with its research and support programs.
Ms Garcia, the team’s captain, hoped for community support.
‘It is an important cause, as most people have been affected by cancer in some way in their lives,’ she said.
‘I am doing it for the memory of loved ones and honouring them.’
Mrs Ray said she would donate her 35cm ponytail to be made into a wig for cancer patients.
The sisters will be outside Mandurah IGA Silver Sands, supporters of the group, on Saturday from 10.30am, with the shave at 11am.
To support the team, donations can be made in person at the Mandurah Coastal Times office, at the shave or www.relayforlife.org.au.
