The fastest circumnavigation by tandem bicycle (male) is 281 days 22 hr 20 min and was achieved by Lloyd Edward Collier and Louis Paul Snellgrove (both UK), starting and ending in Adelaide, Australia, from 7 August 2018 to 16 May 2019.
Lloyd and Louis are both doctors working in Australia. They attempted this record to achieve a boyhood dream.
The journey was made unsupported and the two antipodal points they passed through were Madrid, Spain and Wellington, New Zealand.
