AT A breakneck speed of 15 kilometres an hour, Aussie actor Samuel Johnson is making a difference.
He is unicycling 15,000km across Australia to set a new Guinness World Record, raise $1 million and spread his sister's message of breast cancer awareness.
Samuel cycled through Warwick yesterday and caught up with the Daily News on how his journey is going.
"My average speed (on the uni
cycle) is about 15 kilometres per hour," he said.
"My max speed is 28 kilometres per hour, but that is unsustainable longer than 50 metres.
"I take a break every two hours, which is about every 30 kilometres."
His sister Connie, who has fought cancer three times in her life and is battling with the disease again, is the whole reason behind Samuel's trip.
"When the going gets tough, I think about my sister who has it much worse than I do," he said.
"I imagine her at the finish line and it is a powerful motivator."
Samuel drinks between 5 to 10 litres of water per day depending on the climate, and has gone through two tyres, 35 tubes and 11,421 kilometres.
He has raised $932,246 so far and said the whole trip will take him about 18 months.
"It takes about 15 hours of solid practice to learn how to ride a unicycle," he said.
"It's quite a bit of getting used to."
Samuel said he was overwhelmed at the amount of support from local communities.
"Australia has very warm and generous people," he said.
"There's a very strong sense of community."
Surprisingly, Samuel said one of the most difficult things to deal with on his trip was food.
"I have to eat as much as possible," he said. "It's fuel for my body, but I'm so sick of tucking in all the time."
