Mark Beaumont and James Lowsley-Williams embark on an epic three-day cycling expedition through the wild and wonderful landscape of Patagonia. When first explored by Magellan in 1520, he named the land Patagonia which comes from Pentagon, the Portuguese for 'big feet', since tracks of the nomadic tribes of hunter gatherer's that he found were those of giants. Although any sign of giants has now rescinded, the home of Gaucho is big country with incredible landscapes and impressive volcanoes as far as the eye can see. James and Mark have a 300-kilometre route planned to take it all in.
