Le Tour de la France, exactement(2014)

On August 10, 2011, Lionel Daudet set off on the Dodtour, a circumnavigation of France without motorized transport, following the land border and coastline as closely as possible, from the Alps to the Rhine, from the English Channel to the Atlantic, from the Pyrenees to the French Riviera. On November 15, 2012, he returned to his starting point, the summit of Mont Blanc, after traversing the country on foot, by bicycle, through fields and along beaches, by kayak, and by sailboat, sometimes alone amidst breathtaking landscapes, sometimes accompanied on the outskirts of towns. 3,000 kilometers of mountain ridges, forests, and rivers, and 3,500 kilometers of coastline. A 15-month (465-day) journey to take on a physical challenge, explore, and tell the story of what makes France what it is.
