Stage 10 of the 2012 Tour de France covers 194.5 kilometers and takes the riders from Mâcon to Bellegarde-sur-Valserine. Here is some analysis of the stage from Jean-Francois Pescheux:
Back to the mountains. On paper, the Grand Colombier is a monster. In my opinion, it is the toughest mountain in France, with sections at 12%. Nevertheless, its location 43 km from the finish changes the story altogether. Rather than a single devastating attack, I see a group of five or six strong riders break away and then come together before the finish.
