Confirmation that Quintana now holds a 57-second lead over Valverde on GC, with Froome a further second back - and Contador now almost three minutes in arrears. What a stage going into Tuesday's rest day.

Here's the moment Quintana made his move and dropped Contador to set up his win.
Alberto Contador comes home 1:03 down on Quintana having been passed by Esteban Chaves before the finish...
Robert Gesink takes second place 25 seconds down with Chris Froome just behind, followed by Omar Fraile and Michele Scarponi.
Nairo Quintana (Movistar) wins stage 10 of the Vuelta at Lagos de Covadonga to move back into the red jersey.
Quintana completes the downhill section and is now on the final rise to the line - superb victory for the Colombian today.
Under the flamme rouge for Quintana, who will move back into the red jersey today. He has about 30 seconds now on the chasing trio of Froome, Fraile and Gesink.
Quintana is on the flat section before the final descent and uphill ramp. Froome has caught Gesink and dropped Valverde and Scarponi...
Quintana has a rip in his jersey so he must have come off in one of those early crashes today... and Contador has been dropped by Froome and Valverde! They are catching Fraile now, with Scarponi as a passenger...
Meanwhile, Fraile has ridden clear of Contador, who has been caught by Scarponi, Froome and Valverde. What a stage finale this has been...
Poor Robert Gesink - he's been caught and passed by Quintana.
Froome and Valverde are now just 20-odd seconds behind Contador and Fraile, with Scarponi in between. It's all very poised and very close. All the big guns are within 38 seconds of the lone leader, Gesink.
Quintana is chasing down Gesink on the short descent towards one of the lakes. The Dutchman has 25 seconds. Contador has Fraile with him in pursuit of Quintana.
Scarponi, Fraile and Silin are still holding on to Quintana and Contador. Silin is first to crack. Now Quintana pushes on - and opens up a gap...
Froome has dropped Chaves now and is drawing level with Valverde, in the white combined jersey.
Yates has been dropped as Froome and Chaves ride on in pursuit of the leaders. Valverde is somewhere in between. It's started to rain as well.
Silin and Rolland have been caught by Quintana, Contador and Fraile - and Scarponi is there too. Gesink has just 35 seconds to play with now so it's touch and go for the rangy Dutchman.
Froome has now caught Chaves and Yates of Orica-BikeExchange. He's slowly battling back to Contador and Quintana, who still have Fraile on their back wheels.
Quintana and Contador are in discussion - it looks like the Colombian is asking the Spaniard if he can keep it up, and Contador shakes his head. Momentarily, they are in alliance.
Gesink soloes ahead with Rolland and Silin struggling behind. The Quintana-Contador group is 50 seconds back, with De La Cruz 1:45 down and Froome somewhere in between. Contador and Quintana have caught Dombrowski. They have Fraile holding on. And here comes Froome! The Briton has left Kennaugh behind and is mounting his comeback...
Contador attacks! Quintana follow! And both riders go clear. They've passed Felline and Fraile from the break. Scarponi rides in pursuit... Further back, Froome and Kennaugh have caught De La Cruz, but it's clear that the Tour winner is not on a good day and will lose a heap of time today.
Gesink and Rolland have dropped Silin... and now the Frenchman is starting to suffer on this steep double-digit section.
Valverde, Contador, Quintana, Brambilla, Scarponi and Chaves are riding clear in a main group. De la Cruz, the red jersey, has been dropped. Konig has been released and has joined the favourites, leaving Froome with just Kennaugh.
Sky not panicking yet and both Kennaugh and Konig ride with Froome while he tries to find his feet. They are about to bridge over to Louis Meintjes. If it's not working for Froome then surely Sky will let Konig ride on because he's also well place in the top ten.
Now Rolland rides clear with Silin and Gesink in pursuit. Further back there's Mate, Laengen and Dombrowski. But the main group of favourites - which does not contain Froome - is riding at 1:50. Froome is 30 seconds back now...
Chris Froome has been dropped by the group of main favourites! He's not happy and is talking into his team radio with two Sky team-mates with him. No urgency yet - he usually rides these climbs at his own pace before warming up...
Pierre Rolland bridges over to Vervaeke with a few others in pursuit.
Louis Vervaeke of Lotto Soudal is the first rider to attack the break. The Belgian has kept a very low profile in the break and now makes his move in this early forested section of the climb, with the peloton closing in at 2:22.
Already some of the break have been dropped including Campenaerts, who was doing so much of the pace setting for his team-mate Gesink on the last climb.
Right, we're onto the final climb of Lagos de Covadonga (Cat.HC, 12km at 7.2%). The steepest part is the mid-section before it flattens out twice besides the famous lakes between ramps near the finish.
Silin won the intermediate sprint at Cangas de Onis ahead of Felline and Goncalves, but it's not likely any of these three will win today... although Goncalves has probably the best chance.
The peloton is really strung out as they approach the foot of the final climb. The gap is down to 3:30 and so the GC favourites will no doubt battle it out for the stage win and bonus seconds - unless someone can shake things up from this break, and fast.
The break is back together after that momentary split. The gap is now 3:50 ahead of the decisive climb of Lagos de Covadonga, which is about as mythical as they get in the Vuelta.
The break has split in two with six riders - including Hermans and Dombrowski - edging ahead. Back with the peloton and it's Etixx-QuickStep who are happy to let Movistar do the pace setting on the front.
Meanwhile, Fraile and Mate have been reeled back into the break. Dombrowski is also there so perhaps those reports of his crash were untrue... or it wasn't so bad and he's managed to fight back on. The gap is 4:15.
CRASH: Reports coming through that Joe Dombrowski has crashed on the descent. It's all coming undone for Cannondale: one of their riders has been dropped form the break (Moser), another has crashed, and a third (Rolland) is doing no work and not ingratiating himself to his fellow escapees as the peloton closes in...
Gruzdev and Moser have been dropped from the break, so it's just 12 riders now chasing down the two leaders.
Fraile and Mate have joined forces on the descent and have 25 seconds over the rest of the breakaway. Hermans is having words with Rolland in the break, the Belgian clearly not happy with the Frenchman's sandbagging. Meanwhile, the peloton comes over the summit just over five minutes down.
Now Fraile goes! Last year's polka dot jersey surges clear only to be caught and passed by Mate. But it's the Dimension Data rider who has the strength to come round and power clear to take the summit in pole position. That's 10 points for Fraile, which puts him on 16 points which is good enough for third place in the standings behind co-leaders Thomas de Gendt and Alexandre Geniez, who are tied on 19. Mate, who was on nine, pockets six points so he's onto 15 in total, one behind Fraile.
Camepanerts is still doing all the work despite looking in quite some discomfort. But Mate and Fraile are lurking - clearly prepping themselves for the sprint to the summit.
The break has managed to stretch out their lead on this climb as Camepanerts continues setting a strong pace with Hermans in his back wheel. The BMC rider is no longer the virtual red jersey, it's worth adding. Back with the pack it's the familiar sight of Australian Rory Sutherland setting the tempo for Movistar. 3:30 the gap.
It's LottoNL-Jumbo's Victor Camepanerts who sets the pace for the break - the Dutch team's Vuelta was turned on its head when leader Steven Kruijswijk crashed out in the opening week with that controversial collision with a bollard in Galicia.
The leaders are onto the Cat.1 Mirador del Fito (6.2km at 7.8%). It heads downhill almost immediately after an initial ramp, but then rises at a steady gradient which peaks out above 10%. The 16 leaders have three minutes to play with.
It's a shame about this break coming undone - Cannondale clearly had a plan today and certainly played their cards right. It will be tricky for them to turn things round now, though. If reeled in, these guys will be very much ousted by the GC favourites. Meanwhile, a gap of three minutes just won't be enough at this rate.
We're fast approaching the first major climb of the day after rising up from the coast. The gap has come down to four minutes as the Movistar team-mates of Nairo Quintana move to the front to up the tempo. The sun is back out after an overcast and drizzly beginning. While the break has some solid riders, it won't go the distance is their advantage comes down much more.
It's two years since Poland's Przemyslaw Niemiec won at Lagos de Covadonga the last time the race came here. In total the Vuelta has had a stage finish at the lakes on 20 occasions since 1983 with Pedro Delgado, Lucho Herrera and Laurent Jalabert having all won twice. It was on the road to Lagos de Covadonga in the 1996 Vuelta that Miguel Indurain abandoned his final day as a professional, at the Hotel El Capitan, 20 years ago...
The upshot of this break's ballooning lead is that Belgium's Ben Hermans (BMC) is now the virtual red jersey. Hermans was 4:21 down on De la Cruz this morning in the overall standings.
Etixx-QuickStep have all nine of their riders on the front of the pack, which trails the 16-man break by 5:30 now. They have both the red and green jerseys to protect today although it would be a huge surprise if David de la Cruz manages to hold on to the race lead today. The Spaniard is 22 seconds clear of Nairo Quintana and 41 seconds clear of Alejandro Valverde. Chris Froome is fourth at 49 and Esteban Chaves fifth at 1:19.
Here's what the riders have to look forward to on today's stunning final climb to the Covadonga lakes...
There are some solid climbers in this break besides Messrs Rolland and Dombrowski. Robert Gesink has climbing pedigree while Mate has already been particularly active in this year's race, as has Bakelants. Fraile won the polka dot jersey last year so knows how to ride uphill on his day, while Goncalves proved his strength with a handful of top tens in his maiden Vuelta last year.
Big presence from Cannondale in this break who have climbers Rolland and Dombrowsky, plus rouleur Moser in the break. Solid riders who could do something special today. And it's Moser, who was in yesterday's break, who is now setting the pace on a steep uncategorised peak ahead of today's major climbs. The gap is almost four minutes now. Cannondale's team manager is a happy man...
Fraile was the first rider to have a pop today, sparking a response by some others. Double stage winner Gianni Meersman, the green jersey, then crashed before the race was brought back together after 40km. Meersman's Etixx team-mate Gianluca Brambilla was then in trouble off the back of the peloton. The Italian was off the back in a grupetto for quite some time before the group managed to bridge back over - at around the same time that these 16 escapees broke clear.
Three riders were forced to withdraw from the race following that early spate of crashes: Kevin Reza (FDJ), Markel Irizar (Trek-Segafredo) and Bartosz Huzarski (Bora-Argon18).
There have been numerous crashes today with former race leader Darwin Atapuma (BMC) among a whole host of riders who went down in a pile-up in the opening kilometres in two separate incidents.
The 16 leaders are: Ben Hermans (BMC), Victor Camepanerts and Robert Gesink (LottoNL-Jumbo), Dmitryi Gruzdev (Astana), Tobias Ludvigsson (Giant-Alpecin), Fabio Felline (Trek-Segafredo), Jan Bakelants (Ag2R-La Mondiale), Egor Silin (Katusha), Louis Vervaeke (Lotto Soudal), Joe Dombrowski, Moreno Moser and Pierre Rolland (Cannondale-Drapac), Omar Fraile (Dimension Data), Vegard Staeke Laengen (IAM Cycling), Luis Angel Mate (Cofidis) and José Gonçalves (Caja Rural-Seguros RGA).
We pick up today's stage with 100km remaining and a break of 16 riders currently roll along with a lead of three minutes over the peloton.
Yesterday, Colombian Nairo Quintana was seemingly content to concede the race lead to stage 9 winner David de la Cruz of Spain, who soloed to victory on the Alto del Naranco after riding clear of fellow escapee Dries Devenyns in the last kilometre.
Hola and welcome to live coverage of stage 10 of the Vuelta a Espana, a 188.7km schlep from Lugones to Lagos de Covadonga which should blow apart the GC and give us a real idea of who's going to take the red jersey to Madrid in just under a fortnight.
