As for Jungels, well, he's entered the history books with that ride into pink...
Not a bad way of snaring your first pro win... Bravo Giulio Ciccone!
So after all that Bob Jungels (Etixx-QuickStep) will upgrade his white jersey for a pink - the Luxembourg national champion was in that Valverde chasing group and so takes over the lead from team-mate Gianluca Brambilla.
Then we have Movistar duo Amador and Visconti - but they're followed almost instananeously by the main pack of favourites, who are led over by another Movistar rider, Alejandro Valverde. Wow, the gap came down fast - we must have been given the wrong times along the way...
Atapuma takes third, Brown fourth and Cunego fifth.
Russia's Ivan Rovny (Tinkoff) comes home for second place, 42 seconds down on Ciccone.
Victory for Giulio Ciccone in his first year as a professional! What a ride from the Bardiani-CSF tyro.
Under the flamme rouge for Ciccone, who will win today's stage. It looked like he was working for his team leader Pirazzi, but he proved the strongest in the end.
Brambilla's work for the day is done and the pink jersey drops back. He'll drop down the standings tonight - and Jungels, his team-mate, won't be in pink either. Ilnur Zakarin is now leading the pack.
Visconti is now slowing - probably to wait for Amador and help him extend the lead over his rivals. That leaves Cunego to ride in pursuit of Rovny and Ciccone.
Amador has caught Zoidl. He's 2:10 behind the lone leader so he won't get anywhere near winning the stage - but he has almost a minute on the pink jersey group and so the Costa Rican will move up into the maglia rosa today.
Brambilla looks to be working for his Etixx team-mate Jungels, the man in white, because he's pacing the Luxembourg climber on the front of this main group of favourites. Both of their positions on GC is under threat by Amador today.
What a win this would be for 21-year-old Ciccone - although there's still a long way to go. He's being chased by Rovny, who is in fact ahead of the other four riders, not behind. The Italian has 33 seconds so it's looking good.
Amador has caught Silin from the break, while Brambilla is now leading the pack of main favourites... it's all happening. Remember that Amador has Visconti further up the road as well. Pirazzi has vanished and the chasing group is now Atapuma, Brown, Cunego and Visconti, with Rovny in pursuit.
The final Cat.3 climb to Sestola is 7.5km at 5% so no biggie. This will play into the hands of Ciccone.
Giulio Ciccone, riding his debut Giro, leads the race ahead of the final climb to the finish in Sestola. He has 2:10 over the pink jersey group and 10 odd seconds over team-mate Pirazzi and the new blue jersey Cunego.
Chapeau Brambilla! The Italian is back with the main favourites now - not only that, he's practically on the front of the group as they continue their pursuit of Amador...
CLOSE SHAVE: Steven Kruijswijk's rear wheel locks and the Dutchman runs into Rafal Majka on a tight bend. Amazingly, both riders manage to stay up and continue on their way!
Apparently Brambilla has made up time on the descent and is now only 10 seconds down. Impressive stuff from the race leader - who is not going to give up his pink jersey without a fight.
Attack by Andre Amador on the descent - and the Costa Rican has flown ahead of his GC rivals on this downhill.
Cunego and Pirazzi clash shoulders on a tight bend and almost hit the deck. Meanwhile, Ciccone edges ahead on the descent - which we're told is very technical.
The main pack of favourites go over the summit 2:34 down on Cunego and the other two leaders, with the remnants of the break somewhere in between. It's Andrey Amador who goes over first ahead of the Astana Armada.
Cunego zips clear to take the 35 points atop the Cat.1 Pian del Falco to move 31 points clear of Tm Wellens in the KOM standings (by our estimates). Ciccone us next over ahead of his Bardiani team-mate Pirazzi. So Cunego back in blue tonight. But can he win the stage?
Sergey Firsanov, the climber from Gazprom-RusVelo, is struggling too. He's been dropped by the main pack and is doing his best to fight back.
Now Brambilla is dropping back... two kilometres from the summit and the little Italian is stuggling to stay in touch with the main pack thanks to Scarponi's infernal pace. Bob Jungels is still there, so Brambilla's team-mate will be the virtual maglia rosa now...
Cicconi attacks! The youngster's dig does for Atapuma but he eases up to let Pirazzi and Cunego back.
Preidler has been caught by those four chasers. Impressively, Brambilla is still in the whittled down main pack.
Finally there's a split in the chasing group as Bardiani duo Pirazzi and Ciccone edge ahead with Cunego and Atapuma. Back with the pack, Scarpini and Fuglsang are doing the damage for Nibali.
Ciccone and Pirazzi are taking it in turns to dance on the pedals on the front of this chasing group - but they still can't shed the other escapees. Back with the pack, Astana set a fast tempo and it's caused a huge split in the peloton.
Tom Dumoulin has been dropped by the main pack. There were rumours of him withdrawing from the race on the rest day because of saddle sores, but he's still here. For how much longer remains to be seen. Could he be going the same way as Mikel Landa?
Ciccone attacks from the chasing group to tee up his Bardiani team-mate Pirazzi.
We have a changing of the guard in the peloton as Vincenzo Nibali's Astana team-mates come to the front to up the tempo.
Right, now it's time for the steep part of this climb. Priedler has 25 seconds ahead but he's a big ring rider who will surely suffer as the gradient creeps up.
Cunego, Atapuma and Bonnafond have been reabsorbed into the chasing group on the false flat. Likewise, Folofinov has been caught by the peloton.
Zoidl and Brown attack from that second chasing group. Priedler is on the false flat now, having completed the first third of the climb. The peloton is 3:50 back.
Cunego drags Bonnafond back to the wheel of Atapuma so the trio are together in their pursuit of lone leader Preidler, who has 23 seconds of an advantage. Seven more riders are a further 25 seconds back - including Pirazzi and Visconti.
Atapuma has dropped Bonnafond and rides in pursuit of lone leader Preidler. Bonnafond is then caught by Cunego, the Little Prince, who is after those blue KOM points.
Tom Dumoulin is already in trouble on the back of the peloton. The former maglia rosa has been suffering with saddle sores and he looks very uncomfortable out there...
First attacks coming from the peloton: Alexander Foliforov (Gasptom-RusVelo) bounds clear. He's followed by an Astana rider who is instantly pegged back by Carlos Betancur of Movistar. It comes to nothing and those two are quickly reabsorbed, but Folifonov continues. Paving the way for his team leader Sergey Firsanov, no doubt.
We're onto the major test of the day, the Cat.1 Pian del Falco which comes in three sections: a gentle opening climb (4.5km at 6.9%), a false flat (7.5km at 1.8%), and then a steeper final third (4km at 8.9%) which peaks at 13% near the summit.
Priedler's decision to attack has blown this break apart as Bonnafond jumps clear with Atapuma in pursuit. Back in the pack, Christian Knees of Sky has put in a dig on the descent - trying to salvage something perhaps from a sorry day. If you missed it, read all about what I'm referring to below...
Preidler has managed to keep a gap over the break - he's on this descent with 20 seconds to play with. Meanwhile, Nicola Boem has been caught by the peloton, who trail Preidler by 4:20.
Brambilla back in pink! It's only virtual, but the gap is down to 4:10 for the break so Pirazzi's relinquished his grip on the virtual maglia rosa. It's Pirazzi who's on the front just as Georg Preidler of Giant-Alpecin bounds clear ahead of the uphill intermediate sprint at Lama Mocogno. It looked like the Austrian was on the offensive but perhaps he was just after the kudos of those points and bonus seconds...
Tinkoff and Trek-Segafredo have come to the front to help out Etixx-QuickStep with the tempo. The gap is stable: 4:40 still for the 12 leaders, with a burned-out Boem riding solo in between.
Nicola Boem, who has given his all for his team-mate Pirazzi, has now been dropped by the leading group. The Italian is clearly suffering judging by the range of pained facial expressions he's displaying out there...
The road is really rolling here with a series of uncategorided lumps ahead of the final back-to-back climbs before the finish. The break has 4:45 over the peloton, which has really strung out on the latest uphill drag. Visconti and Silin almost hit the deck after touching wheels, the latter being forced to unclip and steady himself. Visconti apologises, the pair shake hands, and it's all very genial.
The gap is coming down under the pacing of Etixx-QuickStep back in the peloton. Brambilla is bent on keeping the pink jersey because tomorrow the route passes neaby to his home. A rider to watch though is third-place Andrey Amador (Movistar) - the Costa Rican is only 32 seconds down on Brambilla (and 31 down in Jungels) and the final climb today is one that suits his characteristics.
The upshot of these two groups coming together is that Pirazzi, not Visconti, is now the virtual maglia rosa: the Bardiani rider is 4:08 down on the summit while the Movistar man is 4:47 down. Talking of the maglia rosa, Gianluca Brambilla was off the back of the peloton alongside two team-mates - including his dauphin, the white jersey Bob Jungels - but they were just visiting the Etixx car.
We now have 13 riders out ahead after Niemiec was joined by his pursuers. Boem is actually in this break so the Italian was not dropped after all. He's one of three Bardiani CSF riders in this group alongside Stefano Pirazzi and Giulio Ciccone, so the Italian wildcards have a great chance to make a splash today.
Niemiec takes maximum points at the intermediate sprint at Pavullo Nel Frignano. In fact, he rides through solo after Visconti had dropped back to the chasing group, which rolls through just 15 seconds later. The Italian clearly happy to join this strong group, which holds a gap of 5:50 over the peloton.
Lampre-Merida's Przemyslaw Niemiec is the second rider in this two-man leading group and the Polish veteran is no factor on GC having dropped over 20 minutes back on GC. Niemiec has never won a stage on the Giro, but finished sixth overall in 2013 before winning a mountain stage in the 2014 Vuelta.
We overlooked Gio Visconti's position on GC: the Italian was only 4:47 down this morning so he is currently the virtual maglia rosa on the road. Movistar's Visconti is an old hand at his national tour: this is his eighth Giro and he was a double stage winner in 2014 with wins near the summit of the Galibier (on that infamous snow-shortened stage) and two days later at Vicenza.
Nicola Boem has been dropped by the leaders so we have Visconti and Niemiec out ahead now. Boem has also been passed by the chasers too. Perhaps he ate a bit of what Landa had?
Other news from the rest day was the internal expulsion of Russia's Alexey Tsatevich by his Katusha team following his unsporting behaviour in Sunday's time trial in Chianti. Tsatevich had been fined and given a 6:48 minute time penalty by the UCI for "excessive time trial drafting" for "failure to respect regulation distances and gaps between riders" - most notably, Tobias Ludvigsson of Giant-Alpecin, who he sandbagged in front of the TV cameras for around 20km of the 40km race against the clock. In a statement on the second rest day, directeur sportif Dmitry Konyshev said Tsatevich's conduct was "absolutely unacceptable" and therefore the commissaires penalty "was not enough for us".
None of the three leaders are much of a threat to Gianluca Brambilla's maglia rosa but Stefano Pirazzi, in the second group, is 4:08 on his fellow Italian on GC - and he's a pretty tidy climber. That chasing group still trails the leaders by 1:50 but have just over three minutes to play with on the pack.
That Landa withdrawal has really dealt a tough blow to Team Sky, who seem jinxed by the Giro. The British team are now down to seven riders following Elia Viviani's earlier retirement. Landa was 1:18 down on GC and poised to pounce in the mountains. Now their best placed riders are Nicolas Roche, a huge 6:47 down on Brambilla, and Mikel Nieve, an even larger 10:21 down. Both are capable of stage wins, as are Sebastien Henao and Philip Deignan, so that will be the Plan B.
Right, that's it for the catch-up. We're now onto the race LIVE. The riders have been through the feedzone and are now on an uncategorised climb that will take them up to a rolling plateau where the day's two intermediate sprints take place ahead of the final two climbs of the day. The leading trio have 1:30 on the 10 chasers and 4:00 over the peloton, which includes all the classification jerseys. Phew, what a frantic start it has been.
A new 10-man chase group formed on the downhill approach to the feedzone at Ponti di Samone: Guillaume Bonnafond (AG2R-La Mondiale), Stefano Pirazzi (Bardiani CSF), Giulio Ciccone (Bardiani CSF), Darwin Atapuma (BMC), Nate Brown (Cannondale) Damiano Cunego (Nippo Vini Fantini), Georg Preidler (Giant-Alpecin), Egor Sillin (Katusha), Ivan Rovny (Tinkoff), Riccardo Zoidl (Trek Segafredo).
With Landa reportedly seven minutes back on the leaders and four minutes adrift of the peloton, the chase group were caught by the pack. He abandonded after the second climb. Here's the moment the Spaniard threw in the towel and got in the Sky team car...
Giulio Ciccone, Darwin Atapuma and Damiano Cunego tried to bridge that gap on to the three leaders on the second climb of the day, the Cat.3 climb to Pietracolora. They didn't succeed in catching them, but Cunego did take the final point on offer for fourth place. Ahead, Visconti took the spoils ahead of Boem and Niemiec.
Nicola Boem (Bardiani CSF) and Przemryslaw Niemiec joined Visconti on the descent and the three managed to eek out a one-minute lead over the pack at the bottom. But with Landa in trouble behind, Astana were pulling hard on the pack making it difficult for this three-man break.
Giovanni Visconti (Movistar) went over the summit of the climb in pole position ahead of Tim Wellens and Ivan Rovny (Tinkoff). That means Lotto Soudal's Wellens extended his lead in the KOM standings, which was just one point this morning ahead of Cunego.
Mikel Landa was in trouble as soon as the road went upwards on the first climb of the day, the Cat.3 Passo della Collina. Oddly enough, the Basque rider had told some reporters ahead of the stage that he was eager to go on the attack today...
Numerous riders tried to ping off the front ahead of the first climb of the day, including Aussie national champion Jack Bobridge (Trek-Segafredo). The Nippo-Vini Fantini team of Damiano Cunego were having nothing of it, however. They clearly want to see the Italian veteran back in the blue jersey that he conceded to Belgian Tim Wellens on Saturday...
Ok, we've been rather rushed today so we'll now bring you a stage recap and explain what's happened so far on this dramatic day on the Giro...
Team Sky have confirmed the withdrawal of Mikel Landa - we'll bring you more as soon as we get it...
Right, we're back after that live Facebook chat with Sean Kelly. What have we missed? It's probably a quiet day on the Giro surely...
NEWSFLASH: MIKEL LANDA HAS ABANDONED THE RACE! We'll bring you more news on this after the live Facebook chat with Sean Kelly...
There are currently three riders out ahead - Giovanni Visconti (Movistar), Nicola Boem (Bardiani CSF) and Przemyslaw Niemiec (Lampre-Merida) - after the second climb of the day. They are being pursued by eight riders, who trail by two minutes, and then the peloton, who are another 1:30 back. Mikel Landa is a further 3:30 back.
The big early news to bring you, though, is that Team Sky's Mikel Landa - one of the big race favourites - got dropped on the first climb of the day, the Cat.3 Passo della Collina. Reports coming in that he's already SIX MINUTES behind, so the Spaniard is clearly stuggling with some kind of illness after Monday's rest day...
We'll be picking up the race live very soon after a live Facebook chat with Sean Kelly, which you can see by clicking the link below...
Today's stage got under way under sunny skies at Campi Bisenzio, with 184 riders resuming the race after the second of three rest days. It's going to be a tricky one, that's for sure, what with all that climbing on the agenda...
Gianluca Brambilla at the start - the Italian holds a one-second lead on GC over Etixx-QuickStep team-mate Bob Jungels, the white jersey...
With Gianluca Brambilla the surprise race leader going into the second rest day, the 99th edition of La Corsa Rosa has featured more twists and turns than a spaghetti junction. Crashes, withdrawals, chronic collapses on steep gravel tracks – this Giro has come into its own since the three-day Grande Partenza in the Netherlands. And after a Dutchman and a German traded the lead, the famous maglia rosa has found itself a new home with an Italian who doggedly refuses to have his bubble burst. As the Tuscan strade bianche dust settles, let's take a look back as some stand-out talking points from the race since it touched down in the toe of Italy...
Before yesterday's rest day Italy's Gianluca Brambilla held onto the race lead by one slender second on a sodden day in the Giro d'Italia as Slovenia's Primoz Roglic won stage 9 – a lumpy 40.5km time trial through the vineyards of Chianti.
Hello and welcome to live coverage of stage 10 of the Giro d'Italia - an undulating 219km ride from Campi Bisenzio to Sestola which includes four categorised climbs in the Apennines and the Giro's second uphill finish. Fireworks are expected!
