Chen Guanming, a retired farmer first cycled from his home in Xuzhou to Beijing for the 2008 games before travelling from the Chinese capital to London to attend the 2012 Olympics.
Rio 2016 will be the third Olympic Games he will attend.
Chen arrived in Rio this week after riding across the Americas.
A mega-fan of the games, Chen rode his rickshaw across much of North and South America before reaching Rio de Janieiro on Sunday, as reported by the Daily Mail.
Chen cycled 800km from Xuzhou to attend the 2008 Beijing Olympics.
He set out on a two-year-long rickshaw ride through countries such as Thailand and Afghanistan to reach London in a bid to reach the games in time and to spread the Olympic spirit.
Chen was spotted by John Beeston, Managing Director of an insurance brokers compan when he arrived in the UK. Beeston spoke with Chen and discovered his story.
After media reports of his journey, Chen was given a ticket to the opening ceremony in London.
He soon decided that he would attend the Rio Olympics as well.
Upon his return to China, Chen returned to London and travelled to Rio on his three year journey.
He landed in Nova Scotia, Canada, and then travelled across the USA and Mexico before crossing through Latin America and the Amazon to reach Brazil.
Chen reached Rio on Sunday and is preparing for the opening ceremony on Friday.
