As the Tour de France enters the mountain stages today, Frenchman, Thomas Voeckler is still in first place. Five time champion Lance Armstrong, who was briefly in first, is 9:35 behind Voeckler and entering a stage sight unseen. "It's going to be tough. Up and down all day. Unfortunately, it's a stage we haven't seen. It's a hard day ahead." Stage 10 is the longest stage of the Tour at 147 miles and goes though central France. The stage includes a 3.5 mile climb to 5,243 feet.

Tuesday's 9th stage was the shortest non-time trial stage and was won by Robbie McEwen of Australia. Armstrong and fellow climber Jan Ullrich are separated by only 55 seconds, which should bode well for Armstrong, as he and team USPS excel in the mountain stages.
