When tourists visit Western Australia many of them go to places such as Broome, Margaret River and Perth.

But Polish man Mateusz Waligora instead decided to tackle the 1,850-kilometre Canning Stock Route on his bicycle.

The famous inland unsealed road comprises nearly 1,000 steep sand hills, salt pans and crosses three deserts - the Great Sandy, the Little Sandy and the Gibson - and has 48 wells along the route.

The 28-year-old said he heard about the route after a fellow Polish national was the first person to do a completely unsupported solo trip in 2005.

Mr Waligora and his wife Agnieska first attempted the route in 2013, but because of rain, mud and dwindling food supplies, they had to turn back.

"Because of the rain we were stuck at well 46 for seven days and it was muddy from rain and we had food for 40 days maximum, and we decided it would be impossible to finish the route, so we turned back to Halls Creek," he said.

This year Mr Waligora started at Halls Creek in the Kimberley in August and rode into Wiluna in the Mid West 29 days later.

He rode a "fat bike" that has four-inch wide tyres with low pressure that make it easier to ride on soft surfaces than traditional bikes.

Mr Waligora said the question most people ask is "Why?"

"There is no one reason why I am here in Australia to cycle it," he said.

"If the road train drivers ask me, I joke and I tell them that I am trying to lose weight or I don't have a car.

"But is is one of the biggest dreams, Western Australia, especially the Canning Stock Route is one of the most isolated places in the world, so for a cyclist, it is like the really big thing to do to cycle it."

Mr Waligora said temperatures during the ride reached up to 49 degrees Celsius and during one hot stretch lasting three days he drank 36 litres of water.

"It was extremely hot and during the night it dropped to four degrees, and during the day sometimes reached almost 50," he said.

"I had 24 kilos of food, I thought would be enough for 40 days, but I finished the expedition with a lot of it left, because of the heat I didn't eat so much and I lost 16.5 kilos during the expedition.

"There are almost 1,000 sand dunes in the CSR, and I had to push my bike up 80 per cent of them. It was extremely difficult, I was crying, and saying to myself I can't do it.

"I texted my wife every day to let her know I'm ok, still alive."

Mr Waligora said he met some colourful characters on the route, including Helen Canning, whose grandfather is the brother of Alfred Canning, who the stock route was named after.

Mr Waligora said he was looking forward to seeing his wife and new baby son, but he will not be relaxing for too long.

"I always have some plans, some ideas, the south pole on a bicycle, it's possible, two guys have done, so it's possible."
