Macarthur's unique 24 Hour Fight Against Cancer walkathon kicks off on Saturday, October 19, and hopes to draw thousands of local participants to Leumeah's athletics stadium.
If you haven't registered yet - no problem.
A generic "24 Hour Fight" team has been created this year for anyone who is not part of one of many other teams based on friends, families, schools, businesses, churches, or sporting and community groups.
"If no one has a team, or wants to be part of a really big team, this is the way to go," said charity chairman Warren Morrison.
"All you have yo do is go online - 24hrfight.org.au - press the Register Now tab and when it comes to the bit about your team name, write in 24 Hour Fight Against Cancer team."
Many other people simply roll up to the ground during the weekend, buy a T-shirt and make a donation to a great cause.
A lifetime total of $4.3 million has so far been raised by the homegrown charity, which was founded in 2005 by the late Fred Borg.
Dr Stephen Della Fiorentina, director of Campbelltown Hospital's Macarthur Cancer Therapy Centre, calls the 24 Hour Fight a "cornerstone" of local cancer care, with more than 10,000 local cancer patients benefitting.
"It is an enormous privilege to provide care for a community that cares for itself," he said.
Teams come from across Macarthur, from Glenfield in the north to Bargo in the south, and out to Camden and The Oaks. The event lasts for 24 hours but participants can walk for however long they want, with a range of extra attractions from stage entertainment and mass Zumba events to a variety of food and drinks.
The charity provides world-class services and equipment not normally available to local public hospitals.
The main beneficiaries are Macarthur Cancer Therapy Centre and the Oncology Ward and Paediatric Ambulatory Care Unit at Campbelltown Hospital, and the Palliative Care Unit and Outreach service at Camden Hospital.
Among the latest funding extras is a new wheelchair-accessible patient transport bus (which replaced the original Fight-funded bus that had travelled 350,000km since 2007).
Also a lymphoedema therapist to reduce patient waiting times, specialist scanning equipment, and hi-tech treatment chairs for chemotherapy patients.
