"There were lots of people who were travelling north when I was walking south - and they turned their cars around so they could drop money in the bucket.
"If they didn't give money, they honked their horns and gave me a thumbs up."
The Times-Age ran a story on Mr Pedersen's walk, and several people he met en route to Featherston recognised him and offered their support.
"A guy from Clareville offered me a lift - then he recognised me from the paper," he said.
"He handed over five bucks. I think it was his lunch money."
The walk took him seven hours - a half hour improvement on his 2010 Walk for Hope for the Haiti earthquake survivors, with him averaging 10km/h.
He said he enjoyed himself, but was sorely tempted to stop for a tipple once he passed Greytown.
"When I walked past the Tin Hut, I was thinking to myself, 'a beer would go down really nicely about now'," said Mr Pedersen, whose wife Marilyn drove alongside him while he walked.
"I could smell all this barbecue food being cooked as well.
"But I thought, 'nah, I better just keep going'."
"So, I stuck with my bananas, apples and muesli bars."
He hopes to organise further charity events - but none that involve walking long distances.
"My legs might tell me off," he said.
"I was exhausted afterwards. I was fast asleep by 4pm."
Mr Pedersen would particularly like to thank AJ Aporo, his personal trainer at CLM, who helped him prepare for his walk.
