Lance update

Lance and Team Discovery took the overall lead after a time trial in the 4th stage. Lance passed fellow American David Zabriskie of CSC, who fell less than a mile before the finish line.

"It was a very tight matchup as we expected. We kept a good rhythm," Discovery team director Johan Bruyneel said. "We stayed together. It was a beautiful machine operating."

Lance's teammate, George Hincapie, is second and trails Lance by 55 seconds.
