Britain's Chris Froome all-but wins overall race
Froome leads Quintana by 72 seconds with one stage remaining
Stage 21 largely processional into Paris
France's Thibaut Pinot wins stage 20
Quintana was built to climb. He's absolutely flying - he's going to push this all the way. He's past Hesjedal, who reacts and tries to go again.
Quintana is 1min 15secs ahead of Froome. He needs twice as much. Thrilling stuff.
There are two races here. Pinot, Hesjedal and Quintana for the stage. Quintana and Froome for the yellow jersey. Froome is struggling - it's hurting. There are boos as he treads up the climb.
The noise from spectators around Froome is certainly a lot more negative than around Quintana. He may even have been spat at again. The gap to Quintana is one minute. It's growing - but the road might just run out?
Quintana almost looks like he is enjoying this pummeling climb. Weirdo. He's chasing down Thibaut Pinot. Can the Frenchman hold on?
The majority of the crowd are rooting for Quintana. Some are pushing him up the slope. I make it 44 seconds ahead of Froome now.

The gap between Quintana and Froome is sticking, it is not growing. Froome is edging towards glory. But here goes Quintana on a push...
Thibaut Pinot looks set to deliver a bit of French excitement as he romps towards the summit and the finish line. He looks strong.
Quintana is 32secs ahead of Chris Froome.
Image source, EPAThe leaders have hit Dutch corner. It's a bonkers sea of orange - hundreds of supporters who have been drinking most of the day. Now there's a man streaking, buttocks swinging on the road. This Tour has it all.
It's Thibaut Pinot out in front.
Nairo Quintana still has Winner Anacona with him. The camera behind Chris Froome shows that Quintana is out of sight, the gap is 28secs. That'll do for Froome.
Ryder Hesjedal has now taken the stage lead, edging ahead of the AG2R pair.
This is tremendous racing. Chris Froome has Richie Porte with him and Wouter Poels, they are dragging their team-mate up this beast of a mountain, probably towards the yellow jersey.
Quintana is flying through the pack behind the leaders, getting into the slip streams and then springboarding. There is no time gap to Froome yet but there is certainly a gap.
Image source, EPAMeanwhile, Alexandre Geniez has been joined by his A2GR team-mate Thibaut Pinot at the front. Will they sprint it out for the stage win? Ryder Hesjedal is just behind them.
French TV are focusing on this - because two of them are French.
Alberto Contador can't keep with the pace, he's going through treacle. Is Froome in trouble? He has two team-mates with him, but there is a gap.
Like on that first climb, Quintana is off to join his team-mate. Froome just about kept contact on that occasion. What about now?
Nairo Quintana's team-mate, the man third in the GC Alejandro Valverde makes a move, much like we saw on the first ascent. Team Sky are happy to let him go, he won't be making up 5mins 25secs on Froome.
You feel like Nairo Quintana is toying with Chris Froome at the moment, torturing the Brit with surprise attacks. Regardless, the Colombian is running out of road.
10km for Froome to claim a second Tour title.
What about at the front? Alexandre Geniez is 41secs in front of Ryder Hesjedal and Thibaut Pinot.. The yellow jersey group are 2mins 32secs off the leader.
