Britain's Bradley Wiggins all but sealed victory in the Tour de France after winning Saturday's time trial.
Wiggins only needs to safely negotiate himself around the streets of Paris on Sunday to become the first British rider to win the Tour.
The 32-year-old finished ahead of Sky team-mate Chris Froome to stretch his overall Tour lead to an unassailable three minutes and 21 seconds.
Only a crash in Sunday's final stage would prevent Wiggins from winning.
It was a stunning performance from Londoner Wiggins who finished one minute and 16 seconds ahead of fellow Brit Froome in a blistering time of 1:04.13 in the stage 19 time-trial to Chartres.
Wiggins, a three-time Olympic champion, began the 53.5km time-trial from Bonneval to Chartres with an advantage of two minutes five seconds over Froome and he cemented his reputation as the best time-trial cyclist in the world with victory.
He now heads into Sunday's 120-kilometre 20th stage from Rambouillet to the Champs-Elysees in Paris knowing he should return home victorious.
Team Sky principal Dave Brailsford paid tribute to Wiggins following Saturday's victory.
"It is a very proud moment," said Brailsford.
"Bar anything silly we can start thinking about winning this race now. This is a fantastic team and I am very proud right now.
"I would never have said we could do it if I didn't believe that. We had done our homework we knew what Bradley was capable of and what the British team is capable of. Today is all about Bradley and what a fantastic champion."
Froome is also on the verge of history - no Briton has finished on the Tour podium in 98 previous editions, with Wiggins' 2009 fourth place equalling Robert Millar's 1984 best. Now there are set to be two.
