France (AP) - Carlos Sastre of Spain retained the overall lead and Marcus Burghardt of Germany won the 18th stage of the Tour de France as the race left the Alps.
Sastre leads CSC teammate Frank Schleck of Luxembourg by 1 minute, 24 seconds. Bernhard Kohl of Austria is third, 1:33 behind, and Cadel Evans of Australia is fourth, 1:34 back.
Burghardt and Carlos Barredo of Spain finished more than six minutes ahead of the main pack, including the top title contenders, after the 122-mile ride.
The three-week race ends Sunday in Paris.
Meanwhile, officials say French customs agents looking for doping products stopped, searched and released a car driven by the father of Tour de France riders Frank and Andy Schleck today. A customs spokesman says it was part of a random search and the car was not targeted.
