One day, Serge Roetheli came up with a crazy idea--to accomplish something for the children who are lost in this world. Something... by running. This professional mountain guide and former Swiss boxing champ certainly knows how to do that. He had already crossed Europe by globetrotting from Gibraltar to North Cape. Accompanied by his wife, Nicole, who followed him first on a bike, and then on a scooter, Serge ran 24,115 kilometers--the equivalent of 575 marathons! This crazy American Challenge from Tierra del Fuego to Alaska lasted just under three years, from January 10, 1995 to December 4, 1997--a run sponsored by several donors for the benefit of the François-Xavier Bagnoud Foundation in Valais, Nicole's native land and Serge's adopted home. From this modern day epic, there remains a concrete help to the street children of Colombia and this book, where Nicole and Serge tell their story. It tells of the storms of Patagonia, the stifling jungle of Panama, and the icy terrains of Alaska. It also recounts their joys and their pains, their wonderful encounters, the bittersweet anecdotes, the beauty and the misery of continents full of contrasts. It is the human adventure of this century, complete and without complacency. Three years of joy... and of tears.
