Launceston marathon runner Michael Booth is showing no signs of slowing down as he chases an impressive feat.
The 68-year-old has moved another step closer to reaching his goal of running 100 marathons.
Booth recently ran his 93rd marathon, on the Sunshine Coast in Queensland.
It's a long way from humble beginnings in 2002 when he was 48.
"Everything I did was for my wife, my children and our family and I got to 48 years of age and I thought I think it's about time I did something for myself," he said.
"My brother and I, we went for a run up and down Cormiston Road in Riverside where we live and I enjoyed that."
He was quickly hooked.
Booth was then introduced to long-distance running and has not looked back.
He is now the holder of some significant running achievements.
The retired accountant has run the 42-kilometre marathon distance in every Australian state and territory and also on each continent.
"It's a lifestyle," Booth said.
"It's getting out in nature, it's running around the country roads.
"You see scenery that 98 per cent of the rest of Tasmanians don't get to see.
"It's running with friends, the camaraderie, the exhilaration."
He ran his first marathon in Hobart in 2003.
The grandfather from Riverside in Launceston has since taken his running exploits around the world.
Among the 93 marathons he has bagged are the Boston Marathon, Athens, Rio de Janeiro and the Great Wall of China Marathon.
In 2014 he even took on a marathon in Antarctica.
"I believe I'm the only Tasmanian to run a marathon on each of the earth's seven continents," he said.
From Antarctica to the Great Wall
Booth said going to Antarctica was "like visiting another planet".
"We put on layers and layers of thermal gear and we went for a 42km run in the ice and snow and running in freezing water, penguin poo and rocks and everything else," he said.
"We didn't worry about the time it took."
The Great Wall of China was another memorable experience.
"Part of the marathon you run up onto the wall and long and back down, you run through a couple of ancient villages," he said.
"Appreciating that you're running on something that you can see from space and built in ancient times is quite exhilarating."
He has competed in nine out of ten Sunshine Coast marathons, 20 Hobart Cadbury marathons and the iconic Overland Track in Tasmania is among his favourite runs.
He's taken on many of Tasmania's most well-known running challenges; the Three Peaks, Freycinet Challenge, Triple Top and Point to Pinnacle.
In 2019 he took his total running distance to over 40,000 kilometres, the length of the equator.
He runs four times a week.
Sights set on century
The father of four has got seven marathons to go until he reaches his goal of running 100 marathons.
It's a goal he never set out to achieve.
"As those numbers were increasing I realised that my body was probably going quite well," Booth said.
"I was ageing pretty well."
He's hoping his running exploits inspire others.
"You see a lot of retired, especially footballers, who just don't continue in some sort of activity," he said.
"Hopefully I'm encouraging people to take up some exercise and hopefully lead into something just as silly as what I've been achieving."
That hundredth marathon is now within sight.
"There's a very very good chance I will have done them by the end of next year."
But before that, he'll compete in next month's Hobart Airport Marathon.
