Mr Bowthorpe cycled through France, Belgium, the Netherlands, Germany, Poland, Ukraine, Romania, Bulgaria, Turkey, Iran, India, Thailand, Malaysia, Singapore, Australia, New Zealand, Canada and the United States - taking flights where necessary - before coming back to Europe.
This week he pedalled through Spain and France before catching a ferry across the English Channel to Portsmouth where he met his mother and father.
He finished his ride back at his Hyde Park starting point accompanied by his brothers and 20 other cyclists.
The trip around the world raised £55,000 for research into Parkinson’s disease. Link -via Unique Daily
But isn't peddling your ass all over the world count as prostitution? :P
