"I've been involved with endurance events in the past for mountain biking and cycling but running is really hard - especially when you are trying to run 42.2 kilometres."
That's the belief of Narellan Vale's Peter McLean.
Mr McLean is the chief executive of the Can Too Foundation and he hopes that running a solo marathon will help to raise vital funds for up-and-coming cancer researchers.
"There are a few reasons that I wanted to run my own marathon," he said.
"I wanted to run in memory of my father-in-law who passed away from cancer earlier this year, I wanted to really challenge myself and I wanted to finish this tough year on a positive rather than a negative."
Mr McLean will run the marathon around Narellan, Spring Farm and Camden in early December.
"We were supposed run the Honolulu Marathon this year but obviously that plan had to be cancelled due to Covid," he said.
"So I thought, why not challenge myself to run around my home town - and to make it even more challenging I will be doing the run solo.
"And what location is more beautiful than Camden?"
The Can Too Foundation raises funds to support cancer researchers who are in the early stages of their career.
"A lot of cancer charities focus on specific cancer research, like breast cancer or brain cancer, but we support all kinds of cancer research with a focus on young, up-and-coming researchers," Mr McLean said.
"We to support the youngest and brightest minds to help develop innovative research into cancer prevention."
Mr McLean said Can Too also offered a range of health and fitness initiatives for Macarthur locals.
"We know that keeping fit and healthy can improve your overall health and wellbeing, not just physically but mentally as well," he said.
"We also know that it can be a helpful tool in preventing some lifestyle related health conditions and cancers.
"We have a swimming group starting in early November at Bradbury Pools to train for an ocean swim and we have also put out an expression of interest for a running group in the Camden or Campbelltown areas as well."
Mr McLean encouraged locals to support Can Too by taking part in the fitness groups or by supporting his solo marathon.
"There is no better time to support a local who is trying to raise funds for a good cause," he said.
"I think everyone has been affected by cancer either directly or indirectly and this is a great way to show some support."
