EVERY two weeks, Martin resident William Buck donates blood and plasma.
The 28-year-old started doing this a few years ago after his dad, who had cancer, was the recipient of donated blood.
Now, in order to raise more funds for cancer, Mr Buck will jump on his bike and take part in The Ride to Conquer Cancer.
He will do the ride, which is on October 17 and 18, with his friend Sam Loder, who has also had relatives with cancer.
Mr Buck said his 77-year-old dad was like a cat that had nine lives and had been brave throughout multiple illnesses.
“I have been donating for about a year-and-a-half and I think I am up to donation 31 or 32,” he said.
“Both Sam and I have got relatives who have been affected by cancer a couple of times.
“We are just trying to do what we can to stop cancer.”
Participants must raise a minimum of $2500 each to enter the race.
In order to do that, riders have had to come up with different fundraising activities every year.
The pair will hold a screening of the new movie The Martian to raise the funds.
The film is about an astronaut (Matt Damon) who is presumed dead after a fierce storm following a trip to Mars.
He must draw upon his ingenuity, wit and spirit to subsist and find a way to signal to Earth that he is alive.
The screening is at Reading Cinemas in Belmont on October 10.
It begins at 5pm and will be accompanied by various raffles and silent auctions.
Mr Buck has already done The Ride to Conquer Cancer in 2012 and said he was ready for the challenge of riding to Mandurah and back.
