Unless you happen to be Sir Bradley Wiggins or Mark Cavendish, cycling from coast to coast is a massive challenge.
And for Sheffield man Eric Andrews that challenge is made harder still because not only is he 76 years old but he is also registered blind.
Eric is aiming to complete the mammoth ‘Out of Sight’ ride on a tandem bicycle with his son Fraser.
They are doing the gruelling trek to raise funds and awareness for the Sheffield Royal Society for the Blind.
The route will take the pair approximately 140 miles from Whitehaven on the west coast to Tynemouth on the east.
Eric, an active member of the Sheffield Visually Impaired Walking Group, who is in training for his ride, said: “I didn’t realise how uncomfortable bike saddles could be.
“I didn’t suffer like this 60 years ago!
“No wonder the Tour de France riders stand up so much when pedalling!”
Jane Furness, Sheffield Royal Society for the Blind fund raising and marketing officer, said Eric was a real example to others.
She said: “Eric’s determination is an inspiration; when he sets his mind to take on a challenge he makes it happen and we are so grateful for his support.
“Not only is he raising funds, but he is proving that a visual impairment should not hold you back from achieving what you want to do.”
