Mikel Landa moves into the top five with that move today - the Spaniard now 1:09 down on leader Fabio Aru. Team-mate Chris Froome is still six seconds down in second place, while Contador moves back into the top ten at the expense of George Bennett and Quintana rises, too.

Confirmation of the result as Barguil beats Quintana and Contador for the win, with Landa happy to take fourth - and surge up the overall standings.
What a win on the French national holiday for that man in polka dots...
Yates pips Martin for fifth place before Kwiatkowski leads the yellow jersey group over the line 1:47 down.
Yates and Martin are powering towards the home straight...
That's the first French win on Bastille Day since David Moncoutie in 2005.
VICTORY FOR WARREN BARGUIL OF TEAM SUNWEB!
Contador goes early and has Barguil on his wheel ahead of the final bend...
Under the flamme rouge go the four leaders... and they're all potential winners...
Yates is about to catch Martin. They have 10 seconds on the others, if that.
Landa and Quintana drive the pace of the leading group, with Contador and Barguil just behind. They still have 1:55.
Yates still has a decent gap - with Martin further up the road... thrilling stuff.
Chris Froome takes matters into his own hand and surges on the front - Aru bridges over with the others, with only Kwiatkowski distanced - but not for long. The Pole comes forward and Froome latches onto his back wheel. It appears that Yates is a handful of seconds ahead - he must have attacked a bit earlier while we were with the leaders.
Five clicks left for the four leaders, who have 2:10 on the yellow jersey group - so the gap is up.
Martin has opened up a good gap here of around 10 seconds. Louis Meintjes leads the chase, with Aru just looking. His main concern seems to be Froome, so he lets Uran and Bardet zip ahead in the road order.
Uran has been reeled in after his brief flurry off the front. Dan Martin is the next to attack - and there's no response, except from Kwiatkowski... Froome has words with Aru...
Uran has opened up a small gap over his GC rivals on this descent - this is interesting... Froome and Kwiatkowski lead the chase.
Not much love from the aerial helicopter images on this wooded descent... the gap is 1:55 for the four leaders, who are approaching the end of the descent - and will have a fight on their hand to retain that advantage. They should hold for the win, but the gap may be down to under a minute come Foix.
Stalemate on this descent for the big GC favourites. The upshot today is that Quintana and Landa are very much back in the GC picture, Contador's top ten hopes are reignited, and Barguil may get a home win on Bastille Day on a day he moves further ahead in the polka dot jersey competition.
This descent is not as dangerous or treacherous as the one off the back of the Mont du Chat last Sunday - where Richie Porte crashed horrifically into Dan Martin and a wall. There aren't many tight bends and so you can get speed while staying in control. The surface is a bit coarse, for sure, but it's not wet out there and so don't expect any crashes unless riders take stupid risks.
Meintjes, Martin and Yates go forward, covered by Kwiatowski - which means there's a hesitation from the big guns behind, who are busy marking each other out: Froome, Aru, Bardet and Uran. They trail the four leaders by 1:50.
Bardet makes the first move on the descent - prompting a reply from Aru and then Froome. And then Froome continues his trajectory and digs in. MArtin has rejoined these guys, as has Yates.
Another surge from Froome is covered by Aru. They go over the top with Bardet, Uran and Meintjes - and Kwiatkowski is there too, after being caught near the summit. He would prove key to Froome on this descent.
Barguil goes over the top in pole position to take 10pts and move onto 104pts in the battle for polka dots. Job well done for the Frenchman - but can he go one better than Chambery and win the stage on Bastille Day too?
The two leading groups have come together - and behind, it's Froome who makes the first attack, forcing a reaction from the others, except Martin, who is dropped.
Barguil and Quintana are now just eight seconds behind Contador and Landa, whose lead over the yelloe jersey group is down to 2:22. The summit, for them, is one kilometre away as Martin continues setting tempo on this steep climb, with Bardet and Aru behind, and Froome a bit further back.
The impressive New Zealander George Bennett has been dropped by the main pack. He's been a revelation for LottoNL-Jumbo in this race and is targeting a top ten finish in Paris.
It looks like Simon Yates is riding very much for the white jersey rather than anything else: the young Briton is on the back of this main pack of eight, riding in the wheel of Meintjes (who he leads by 2:38 in the youth standings).
Landa and Contador have 2:35 on the main group of eight - so it's coming down. They should hold on to contest the stage win, but I doubt Landa will be in yellow now come Foix.
The Quintana-Barguil chasing group has slashed the gap to 40 seconds while Dan Martin drives the pace in the main pack, with George Bennett just behind. They're down to those two, Froome, Aru, Meintjes, Uran, Bardet and Yates - so the top eight in the standings, with the ninth, Landa, further up the road.
You may remember the Mur de Peguere from the last time the race came here - in 2012 - when "fans" threw carpet tacks on the road, causing the neutralisation of the descent... Luis Leon Sanchez won that day, while Cadel Evans - the defending champion - was one of many riders to puncture.
Kwiatkowski has been dropped by Barguil and Quintana, but this chasing group is flagging: they're 55 seconds down now. Quintana is not the rider he was last year - this ambitious Giro-Tour gamble really hasn't paid off.
The gap is growing for our two Spanish leaders, who have 2:40 over the Aru main pack. That puts Landa within 15 seconds of the virtual maillot jaune. They are 3.5km from the summit.
Gallopin was with compatriot Romain Sicard of Direct-Energie, who has now caught Vuillermoz, who was dropped from that chasing group earlier.
Tony Gallopin, who had attacked the main pack on the last climb, has just been swept up. Two UAE Team Emirates riders are setting a fast tempo - Ulissi is one of them. The other doesn't look like Meintjes, mind. But the South African is here - alongside the likes of Aru, Froome, Bardet, Uran, Martin, Yates, Bennet, Nieve, Latour, Caruso, Betancur, Pauwels, Mollema, Roglic, Castroviejo, Gastauer, Perichon, Bettiol, De Marchi, Kiryienka, Knees.
Jakob Fulgsang has abandoned the race. He was well over 4km behind the leaders and that makes sense given his injuries. The Dane broke bones in his wrist and elbow two days ago.
Landa and Contador were never caught by the three chasers and they have 25 seconds now with the pack at 2:25.
We're approaching the third of these three quick-fire Cat.1 climbs - and it's the hardest: the Mur de Peguere (9.3% at 7.9% with some sections of 18% and 16%).
The two leaders have completed the descent and are heading towards the foot of the next climb, the infamous Mur de Peguere. They're going through the feed zone and have the three chasers just behind them, so expect this to come back together - and Sky will then have the numerical advantage. The yellow jersey chasing pack are still 2:20 back after Bardet and Froome's acceleration was called to heel.
The three chasers - Kwiatkowski, Quintana and Barguil - are just 15-odd seconds behind the leaders now, but the gap back to the peloton from Landa and Contador has been slashed to 2:15 with the flurry of attacks.
Bardet and Froome have attacked on the descent! Uran has it covered - and Aru is forced to respond.
With the yellow jersey pack crossing over the summit at 2:39, Mikel Landa is now just 16 seconds away from being the virtual yellow jersey. The Spaniard was 2:55 down on Aru this morning - and this is the worse case scenario for the Italian: he's isolated and committed himself to marking Bardet and Froome - but in doing so he's let some strong riders go up the road, and once those two groups come together, the gap may only get larger...
Contador takes 10pts over the top of the Col d'Agnes, with Landa just behind for 8pts. Barguil leads Quintana and Kwiatkowski over about 25 seconds down. So, the Frenchman moves on to 94pts in the KOM standings. His polka dot jersey is looking more and more assured.
Vuillermoz has been dropped from the chasing group...
Betancur has been dropped by this four-man chasing group of Quintana, Kwiatkowski, Vuillermoz and Barguil, the polka dot jersey. They're still 40 seconds down, with the pack another minute further back. Stunning scenery today on the Tour...
Right, out two leaders have 40 seconds on the Quintana chasing group and 1:38 on the main pack. Aru, the yellow jersey, is completely isolated - he has no Astana team-mates whatsoever. Froome has Nieve, with two others up the road, while Bardet has two with him here, and one - Vuillermoz - up the road, too.
Our two leaders - Landa and Contador - have 1:20 on the yellow jersey group. They are collaborating now. Initially, Landa chased down Contador to cover the attack - even though the Trek rider is seven minutes down in 11th place on GC. But now it appears that Sky are going to keep him there to try and win the stage. They have Kwiatkowski behind shadowing the attack from Quintana, who is four minutes down in 8th place on GC, while Nieve is still with Froome in the main pack. But should Landa get a few minutes today, then Sky would have a leadership conundrum...
De Marchi has been dropped so it's Spanish duo Contador and Landa who are in the lead - but their advantage is only 32 seconds on the yellow jersey group, which contains all the big guns in Aru, Bardet, Uran, Froome et al.
Attack from Movistar duo Nairo Quintana and Carlos Betancur! The Colombians are in need of shaking things up for their team - and they've caught Barguil, who has been dropped by the leaders, while Kwiatkowski is there as well, and Alexis Vuillermoz for Ag2R-La Mondiale.
It's hard to see what is going on because there are groups all over the road. Landa, Contador and Barguil have caught De Marchi. They have 28 seconds over the yellow jersey pack - and Froome is with them again after being distanced a bit on the last climb.
The descent from the Col de Latrape is done - and the riders are straight onto the next climb, the Cat.1 Col d'Agnes (10km at 8.3%).
De Marchi crests the summit in pole position with a small gap over three chasers: Barguil, Contador and Landa. Barguil was second and so adds 8pts to his tally. Clever riding from the polka dot jersey, who's up to 88pts now.
Chris Froome appears to have been dropped! The defending champion is surrounded by Sky colleagues in a second pack, with the likes of Aru, the yellow jersey, and Bardet in a group a few seconds ahead. Barguil has attacked - and so has Alberto Contador. And Mikel Landa as well!
De Marchi - who is free to follow his own ambitions now that team-mate Richie Porte has crashed out - is 1km from the summit and he has 25 seconds over the pack...
Sylvain Chavanel is back with Gilbert, but they're about to be caught by the chasers. In fact, as they close in, the Frenchman digs in to open up another small gap. Chavanel knows this climb well: he crested the summit of the Col de Latrape in pole position in 2004.
Riders are being shelled out of the peloton at quite a rate. Michael Kwiatkowski of Team SKy is setting a fast tempo on the front of the pack - in fact, he's ridden clear of the pack with Jesus Herrada of Movistar, and they've caught some of the chasers, such as Ulissi. On the front, De Marchi has ridden clear of Chavanel, who has in turn dropped Gilbert. But this is all happening in the space of 35 seconds...
Fuglsang is really in trouble - the Dane is struggling to hold the handlebars, with those wrist and elbow fractures. The problem for him is that going up is just as bad as going down - and there's a lot of that today, in quick succession.
Chavanel is setting the tempo on the front and Calmajane has attacked from the chasing group - so Direct Energie are playing their cards. The gap for the three leaders is just 34 seconds and so it could all come back together yet. On the back, Fuglsang has been dropped again.
The three leaders are onto the first climb of the day, the Cat.1 Col de Latrape (5.6km at 7.3%) which includes some segments of around 10%.
There's a group of nine now in pursuit of the leaders: Mollema, Calmejane, Poljanski, Wyss, Ulissi, Lammertink, Arashiro, Pasqualon and Burghardt (who didn't drop back - sorry, I made a hash of that).
It looks like Burghardt was just launching that attack for his team-mate Poljanski, who now has Lilian Calmejane (Direct-Energie) with him in pursuit of the three leaders. A very attacking start to this short stage - just as we expected. The first climb is coming right up.
Frenchman Pierre Rolland (Cannondale-Drapac) has made an attack from the peloton - sparking a response from numerous riders, including Andrey Amador (Movistar) and Thibaut Pinot (FDJ). But it comes to nothing...
The leading trio of Philippe Gilbert (Direct Energie), Sylvain Chavanel (Direct Energie) and Alessandro De Marchi (BMC) have two Bora-Hansgrohe riders in pursuit: Pawel Poljanski and Marcus Burghardt. They have about one minute over the peloton.
Vichot's withdrawal means FDJ are down to just four riders now! Their race started well with a Stage 4 win for Arnaud Demare, who also enjoyed a stint in green. But when the French national champion got ill, he struggled in the Vosges and Jura - and was kicked out of the race along with three team-mates when they made a hash of finishing within the time cut. Headaches for their manager Marc Madiot... Still, with only four riders, they only need one team car in the cavalcade now.
We're hearing that Arthur Vichot of FDJ has withdrawn from the race. The former French national champion calls it quits on Bastille Day - that's sad news to hear. He was involved in a crash a couple of days ago.
So, that's 13 points for Matthews and 10 for Kittel, which means the German now has 362 points in the green jersey standings, with his Australian up to 235. As long as Kittel stays in this race, he'll take over Peter Sagan's green crown - but you never know what may happen, hence Matthews continuing to plug away...
But before that, there's the small matter of the intermediate sprint - which has provoked a flurry of activity from behind in the pack. After Voeckler and Barguil were reeled in, three more riders pinged clear: Chavanel, Gilbert and De Marchi. They mopped up the points at the sprint, with Michael Matthews edging Marcel Kittel behind for fourth place.
The reason why Barguil is in this break - besides wanting to be a Bastille Day stage winner - is that the Frenchman leads the polka dot jersey standings, which he will hope to consolidate today. Team Sunweb's Barguil has 70pts in that competition with his nearest rival being Thomas De Gendt of Lotto Soudal, who has 32 points. There are 30pts available today: 10 for each Cat.1 climb.
Our two leaders - Barguil and Voeckler - are struggling to make any headway. They have about 10 riders in pursuit, but the gaps are minimal, and Voeckler is already shaking his head.
A reminder that Fabio Aru leapfrogged Chris Froome into the yellow jersey yesterday on that final steep ramp at Peyragudes. The Italian is six seconds clear with yesterday's winner Romain Bardet in third at 25 seconds. Rigo Uran was 35 seconds behind in fourth - then he sunk to 55 seconds in arrears after the jury penalised him for taking on a bottle in the last 10km. But then the jury reversed the decision, so he's back up to 35 seconds in arrears. Dan Martin completes the top fiva at 1:41.
Trouble already for Denmark's Jakob Fuglsang... Two days ago and the Dauphine winner was fifth on GC. Then he crashed in the feed zone in Stage 11, fractured bones in his elbow and wrist, then shipped 27 minutes in the Pyrenees yesterday. He would be a key Astana team-mate for Fabio Aru, the new yellow jersey, but as it is, he's struggling to stay in this race.
Analysis from yesterday's explosive day: As Team Sky dragged Chris Froome to the bottom of the final climb in Stage 12, it looked like the same old story for the Tour de France. But then the yellow jersey cracked, his rivals pounced and the Tour took off on the Peyragudes altiport. Strap in: we may just have a race on our hands…
Just a small gap for our all-French break as numerous riders try and bridge over from behind. An active start to the stage - and one which should blow this race apart.
This is what's on the menu today: three steep Cat.1 climbs and a fast finish in Foix. Oh, and the small matter of an early intermediate sprint.
ATTACK: And Thomas Voeckler (Direct-Energie) attacks from the gun - and he takes another Frenchman, Warren Barguil of Team Sunweb, with him.
Without further ado, let's get stuck right in - because the riders are in the neutral zone... and Christian Prudhomme has just waved the flat to get this stage under way!
Yesterday, Fabio Aru sensationally zipped into the lead of the 2017 Tour de France after yellow jersey Chris Froome hit the wall on the ramped finish to Stage 12 in Peyragudes on a day Romain Bardet won with panache in the Pyrenees.
Hello and welcome to live coverage of stage 13 of the Tour de France: it's Bastille Day and the whole nation - nay, the whole world - is in for a right treat, with this short but sharp 101km stage from Saint-Girons to Foix.
