“The longest journey by motorcycle in a single country is 33,357.15 km (20,727.13 miles) and was achieved by Buck Perley (USA) and Amy Mathieson (UK) who rode throughout China from 19 July to 11 December 2013.“
The journey took Buck and Amy 146 days and through each of China’s provinces on a CFMOTO 650-TK motorcycle. The duo, a couple, also raised more than $10,000 in contributions to the Free Lunch for Children charity.
I would write more about their journey, but they have a great blog that includes some great pictures from their journey. See some highlights from their trip including their stories of beginning their journey in Beijing, crashing in Heilongjiang, getting caught in a sandstorm at the lowest place on earth, and traveling up Everest.
