A car driven by the father of Tour de France stars Andy and Frank Schleck (CSC-Saxo Bank) was searched by French customs during the 18th stage, which began in Bourg d'Oisans on Thursday.
An official source in Grenoble later said that "no doping products or banned substances" were found during the long search, which took place at Vizille in the Isere region of the Alps.
Andy Schleck suggested "jealousy" may have been behind the search.
Stage 18, Bourg-d’Oisans to Saint-Etienne, 196.5km
Weather Sunny and warm, clear skies, temperatures in the low 80s.
Stage winner On a day destined to see a winner come from a breakaway, Columbia’s German Marcus Burghardt took his first-ever Tour stage win out of a two-man breakaway, ahead of Quick Step’s Spaniard Carlos Barredo.
After battling his way through the 18th stage of the Tour de France Thursday, despite sustaining potentially serious injuries in a crash, Lampre's Damiano Cunego has pulled out of the race, according to team sources.
"It's a miracle I finished this stage," said the Lampre rider, who came over the finish line with blood dripping from a wound under his chin and injuries to his chest and thorax.
After yesterday’s insanity on the climb, today’s came at the start area. As we drove down the Alpe, thankfully in cars with the bus waiting at the bottom, there were still hundreds of people camped out roadside.
Spanish cyclist Moises Duenas, who was kicked out of the Tour de France after failing a drugs test, on Thursday denied knowingly taking any banned substance during the race.
Duenas was charged last week in France with "use and possession of plants and poisonous substances,” and dropped by his British-registered team Barloworld. He risks a two-year jail term and a 3750-euro fine.
Stuart O'Grady finally came through one of his "toughest" Tour de France campaigns as the peloton headed out of the Alps and steadily towards Paris on Thursday.
However, the Australian admitted he almost never made it as far as the second mountain range of this year's race after finding out he was carrying a virus three days into the race,
"I didn't know it at the time but I was a bit crook. It turned out it was pretty serious," O'Grady told AFP. "When the results came through it was actually a relief."
Swiss pharmaceutical giant F. Hoffman-La Roche issued a statement Thursday disputing a recent claim by World Anti-Doping Agency chief John Fahey that it had inserted a “marker” in its new anti-anemia drug Micera.
The drug has been the focus of recent attention after Ricardo Riccò, Saunier Duval’s top GC hope at the Tour de France, tested positive for the drug following the stage 4 time trial at Cholet.
After spending almost all of the day on the attack, Team Columbia’s Marcus Burghardt won the 18th stage of the Tour de France, beating Quick Step’s Carlos Barredo in a final kilometer chess match that bore more resemblance to a match-sprint on the velodrome than the end of a 196.5 mile road race.
The two joined forces early in the day and cooperated until the final ten kilometers. At that point the two could afford to risk the benefits of cooperation as they enjoyed a healthy 4:50 lead over a group of three chasers and nearly 10 minutes on the peloton.
From virtually every aspect, Carlos Sastre has ridden a perfect Tour de France. As soon as the route for this year’s Tour was announced last October, he said that the race would be decided in the final week, and probably at L’Alpe d’Huez. That’s why he focused his whole season on being at his very best right now, using races as training all season long, and trying to remain anonymous through the first two weeks of the race itself.
