An idea that was conceived in 2014, formed out of the looming question of "what is possible in a lifetime?", has snowballed into one of the biggest challenges taken on by a team of British explorers this decade. John Whybrow and George Agate will cycle their tandem bicycle, unassisted and carrying all their required equipment, for 18,000 miles, starting and finishing in the historic city of Canterbury, Kent.

The goals? To set the Guinness World Record for the first team to circumnavigate the World by Tandem. To open the eyes of many to the humans of our world and its vibrant population. To enthuse people to get on their bicycle and outside for an adventure. And to have a bloody good time doing it.

This expedition will take them on a route that heads eastwards, across the flats of Europe, through the Orient, traversing the Australian outback, and cruising the Pan American Highway. 4 continents, 28 countries, 2 Men and 1 Record.
