Mr Hart said he planned to cycle 2000km from near Madrid in Spain to London over 20 days and had been fundraising for Telethon.
He will be travel solo, with all his food, water and camping equipment strapped to his bike, so he has started to build up his strength before he leaves Perth on May 31.
‘A lot of the weight is all the things I have to carry ” a tent and sleeping bag, 4kg in water,’ Mr Hart said. ‘I’ve changed my training ” added a sack of rocks to the bike.’
The father-of-two said his 10-year-old daughter had been helping with his training and his 18-year-old son helped on the computer.
‘I rode to Denmark and Walpole ” 500km in five days,’ he said.
‘The longest single day I’ve done is 105km. This is the first time I’ve done anything of this magnitude.’
Although he hopes to do about 120km a day, Mr Hart said he had not planned every detail of his trip.
‘I want flexibility to keep going if I’m feeling strong, or stop when I need to,’ he said.
‘It will be interesting to not know where I will be sleeping the next day and hopefully I find some food along the way.
‘The plan is 20 days of cycling but I’ve got the whole month off.
‘If I run into trouble, then I’ve got a few days spare.
‘At the end of the trip I’m going to see my family and friends in England.’
Although he now cycles to work at Edith Cowan University in Joondalup or Mt Lawley every day, Mr Hart said until four years ago, he had not ridden a bike since he was a child.
‘When I first started, I just bought a $30 bike from a garage sale ” I couldn’t even ride 10km,’ he said.
