Bradley Wiggins moved to within touching distance of Tour de France glory after winning the stage 19 time-trial from Bonneval to Chartres.
Wiggins will become the first British winner of the Tour during the year in which it celebrates its 99th edition.
The Londoner extended his lead at the top of the leaderboard with an imperious performance which saw him storm to victory over the 53.5km stage.
Starting the day with an advantage of two minutes 5 seconds over Team Sky team-mate and second placed man Chris Froome, Wiggins knew he had an excellent chance to all but seal his first title, barring any major mishaps.
Froome blitzed the stage, finishing in 1h 5min 29secs, but Wiggins was in his groove and took victory 1min 16secs quicker than his compatriot.
With just tomorrow’s 120km ride from Rambouillet to the Champs-Elysees to go, it will be a procession finish for the British pairing, as they look to seal an unprecedented 1-2 finish and firmly underline the quality of British cycling and the dominance of Team Sky.
