Returned last month from doing a 2 week stretch on the Bibbulmun track. My friends and I are doing it bit by bit every few years.
Anyway we came across an incredible bushwalker out of Balingup who goes under the name of 'Pack Animal' aka Dave. 'Pack Animal' was doing his 13th complete end to end of the Bibbulmun - thats about 13000km when he finishes!! Thats like walking from Perth to London.
So what is he doing when he finishes this walk - he's turning around and doing it again. His plan is to get up to 16 or 17 times to make sure he has the record. And thats when he will think about doing a different walk. He walks in sandles too!
