In a "harebrained" 2,642-kilometre journey down the Murray River on his stand-up paddleboard, Peter Charlesworth's aim is for regional Australians to take their heart health seriously.
Hailing from the New South Wales border town of Albury, Mr Charlesworth has already completed 2,000km of his trip.
As part of an ultra-distance Guinness World Record attempt — with no support crew — he's paddling the length of the Murray River as well as lakes Hume, Mulwala and Alexandrina.
