Spaniard Alberto Contador took a virtually unassailable lead in the race for the Tour de France yellow jersey after winning the race's 18th stage time trial on Thursday.
Contador, the 2007 champion who rides for Astana, clocked a time of 48min 30sec to beat Switzerland's Olympic champion in the discipline, Fabian Cancellara, by three seconds.
Russian Mikhail Ignatiev, of the Katusha team, was third at 15sec. Seven-time champion Lance Armstrong, also of Astana, finished in 16th place 1:30 adrift of his Spanish teammate, but despite that mediocre result the American moved up one place in the race's general classification to third.
Unless he experiences a sensational collapse on Saturday's 20th stage when the peloton finishes on the summit of the legendary Mont Ventoux, Contador is now virtually assured of winning the race.
Ahead of the 19th stage, which is likely to be dominated by breakaways, the 26-year-old Spaniard has a lead of 4:11 on Luxembourg's Andy Schleck of Saxo Bank while Armstrong is third overall at 5:25.
Having reinforced his grip on the yellow jersey by winning the stage to the race's second summit finish at Verbier in Switzerland on Sunday, Contador's win in the race's other crucial event has cemented his status as the best stage racer in the world.
It was also a bold statement, coming a day after he defied orders from team boss Johan Bruyneel. Bruyneel told him to allow the Schleck brothers Andy and Frank to go off on their own and to stay behind with teammate Andreas Kloden — a tactic that could have allowed Contador, Armstrong and Kloden to finish the day in first, second and third positions.
“For me to win a time trial at the Tour, it's just huge. I went out hard but thinking only to protect my place in the GC. But when I got to the first time check and saw my time it gave me a bit more belief.”
