“We did it. We – the Vogel family from Boise, Idaho – did it. We did the impossible, and I couldn’t be happier that we did,” wrote Nancy Sathre-Vogel, in her family blog, when she and her family reached Ushuaia, in Argentina.Eight years ago, John and Nancy Vogel left their teaching jobs, took their twin boys out of school, bought two single bikes and a tandem and embarked on a journey to cycle the Pan-American Highway.The Pan-American Highway is a network of roads, extending from Prudhoe Bay, Alaska to Ushuaia, Argentina. According to the Guinness World Records, the 48,000km highway, which runs through the North and South American continents, is the world’s longest ‘motorable road’.The highway comprises official and unofficial sections. The official section runs from Nuevo Laredo, Mexico to Buenos Aires, Argentina, while the unofficial sections can be found to both the north and south of the official route.The route — including the official and unofficial sections — spreads across 14 countries: the USA, Canada, Mexico, Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica, Panama, Colombia, Ecuador, Peru, Chile and Argentina.However, if you are thinking in cycling or driving all the way down until Ushuaia without stopping — except to rest, sleep or eat — take that out of your mind.The route is interrupted by a 160km-wide break, named the Darién Gap, between Central and South America.The Pan-American Highway is for many the ultimate road trip and here — as part of the WCN’s Roads Week — we provide you with everything you need to know, so you can start, if you fancy the challenge, your ‘little’ adventure.
