BEN Ferris has stopped in at North Stradbroke Island on his latest long-distance journey, an attempt to run more than 2000 kilometres on water from Byron Bay to Cairns.
Mr Ferris - nicknamed Ferris Gump - made headlines in 2016 when he ran from Townsville to Darwin via Cairns raising money for the Royal Flying Doctor Service and St John Ambulance.
In March, he completed a run from Sydney to Byron in his thongs and budgie smugglers in aid of drought-stricken farmers.
He has also run in Indonesia and Belgium.
The latest leg of his journey began on April 6 when he set out from Byron Bay on a Hobie Marina Eclipse, a stand-up paddleboard fitted with pedals and handlebars.
He expects the journey to take between 70 and 80 days, with eight hours pedaling on average per day.
On his record-breaking journey, Mr Ferris aims to raise $20,000 via his GoFundMe page to support the Seabin Foundation and have marine bins installed in harbours across Australia.
Seabins suck floating rubbish from the water surface, collecting and storing debris before pumping the clean water back into the harbour.
"I just want to see the oceans clean," Mr Ferris said.
"I want our kids to be able to have a clean environment too."
He said he hoped his journey would inspire people to get outdoors and build their connection and respect for the environment.
Passing through the Redlands on Monday, Mr Ferris stopped to camp at Dunwich on North Stradbroke Island, as well as popping in at Russell Island and Raby Bay.
His journey has not all been smooth sailing.
As well as facing rough weather and broken handlebars in his first week of travel, Mr Ferris found himself stranded on a sandbar after leaving Straddie.
"I was cruising along and...I thought I'd take a shortcut (over the sandbar)," he said in a video on his Facebook page.
"(I thought) I've only got to carry (the board) over the sandbar for a little bit...(but) the little bit turned into a long bit.
"The short way is not always the best way in life."
On Monday, Mr Ferris travelled around 50 kilometres up the coast and along the river to the Brisbane CBD, arriving at the Story Bridge after 9pm.
He documents his journey on his Facebook page RunFerrisRunn, where he has amassed a social media following.
Mr Ferris said people would come to see him as he passed their stretch of coast.
"I think it helps bring the community together," he said.
"We're moving towards a sustainable future. We have to."
