The Mondo Enduro round the world motorbike expedition attempted but did not cross the Zilov Gap in Central Siberia. In 2000 a follow-up expedition, Terra Circa, was organised by Dave Greenhough, brother of one of the Mondo Enduro team members. It was the first motorbike expedition to cross the infamous Zilov Gap. The route went from London across Europe, western Russia and Siberia to Vladivostok. The team then embarked for Japan and returned to Europe crossing the United States. It took 7 months and they drove 20 000 miles.
