The 72-year-old set off on the seven-day journey from Esperance on Saturday, with friend and former Masterchef contestant Josh Catalano to raise money for the McCusker Alzheimer’s Research Foundation.
“Josh lost his grandma to Alzheimer’s,” Cable said.
“We are determined to find a way to ensure other families don’t go through the same experience.

READ NOW“I also know a few people who have Alzheimer’s. So I thought because I’ve done a lot of rides over the years for lots of causes, I’d do this one too.”
Alzheimer’s is the second largest killer disease in the country behind cancer and affects more than 350,000 Australians.
That figure is set to rise to 1 million by 2050, without a significant medical breakthrough.
Foundation chairman Enzo Sirna thanked the pair for their efforts.
“I want to thank Barry and Josh most sincerely,” he said.
“To see the completion today is really a humbling experience.
“I hope it has created that important awareness along the way that hopefully one day we will find a cure to Alzheimer’s.
“But for today, I think we need to respect this wonderful effort.”
Cable had been riding 500km a week in preparation for the ride, but said he would be putting the lycra away after this one.
“The fact that I’m getting on myself, I thought I’d make this the last big ride I do,” he said. “I hope my wife Helen looks after me the next couple of days because I won’t be getting out of bed.
“I don’t want anyone else’s mates or family to go through the suffering of this disease.”
So far, more than $10,000 has been raised from the ride. To donate, visit www.everydayhero.|com.au/event/ride-for-memories.
