The ASO messed up and accidentally published the 2012 Tour de France route on letour.fr. They realized their mistake pretty quickly, but not quick enough. Inrng got it, as well as Cyclingnews. Check those sites to see the route. Note the total distance of time trials (96 km).
And now, allow me to make my prediction for the winner of the 2012 Tour de France: Alberto Contador. You heard it here first.
