Lance Armstrong's Discovery Channel cycling team has won the team time trial at the Tour de France, giving the six-time champion the overall race lead.

The American, 33, led his team to victory in the time trial for the third straight year. Tuesday's fourth stage ride was 67.5 kilometers from Tours to Blois, and the Discovery Channel team clocked one hour, 10 minutes, 40 seconds. That is an average speed of 57.32 kilometers per hour, shattering the old mark of 54.93 kilometers per hour set in 1995 by the Geweiss-Ballan team.

Team CSC placed second in Tuesday's fourth stage, only two seconds behind. CSC rider David Zabriskie of the United States, who came into the stage in the leader's yellow jersey, fell in the last kilometer. The T-Mobile Team was third, 36 seconds off the pace.

With the team win, Armstrong will wear the yellow jersey for the 66th time in his Tour career. Discovery teammate and fellow-American George Hincapie is second overall, 55 seconds behind Armstrong. German Jens Voigt is third overall, one minute, four seconds off the pace, and his CSC teammate Bobby Julich of the United States is fourth, one minute, seven seconds in back of Armstrong.
