0km - Looks like Nibali will also take the red jersey.
0km - After five and a half hours of racing it is Duarte who wins the 'sprint' for second from Rigoberto Uran and Carlos Betancur. That means that Betancur will take the white jersey and Uran will leapfrog Cadel Evans to move into second place.
0km - With the Maglia Rosa on his shoulders Vincenzo Nibali battles the elements to take the stage win, the Cima Coppi and with it the overall win in the Giro d'Italia 2013. It's been a tough three weeks, but he has been by far the strongest and now he has a high mountain stage to add to his time trial win on Thursday.
.5km - The snow is getting heavier as we hit the top and Nibali is just ticking over to get to the finish.
1km - Three Columbians are now chasing Nibali but it will matter not to the Maglia Rosa as he has this stage in hand. The battle for second and the battle for the white jersey continue behind.
1.1km - Durate (Columbia) has come out of the group behind and is struggling to stay with the pace of Uran and Betancur, as Nibali goes under the red kite.
1.2km - Betnacur is caught by Evans but looks like he is only watching Majka and is not interested in pushing any harder than he has to.
1.4km - Evans is still working, but he hasn't reached the wheel of Uran just yet. He is being followed by Majka and Italian champion Pelozotti.
1.5km - Nibali looks totally focused and almost comfortable in this totally white mountain. He's being surrounded by crazed fans and has to slap them away.
1.5km - Evans continues to grind away behind and is gaining ground on Uran and may well hold on to second place if he can catch him.
2km - Betnacur (AG2R) may well be in a position now to steal the white jersey from Majka as it looks like the Columbian is the stronger of the young riders.
2km - Nibali goes again as he overtakes Capecchi. He leaves Betancur, Majka and Uran in his wake. He's opening up a lead now and the two Columbians are trying to work together. We're on a ramp of 18% at present.
2km - Capecchi is still out front and being chased down by Nibali now. Nibali keeps digging and looks like he is putting daylight between himself and the Columbians, Uran and Betancur.
2.5km - Nibali is still pushing on and has Uran, Brtancur and Majka for company. The only one that wil concern him is Uran but he has over 4 minutes on him. Evan has been dropped.
3km - Nibali pushes on at the front and is joined by Tanel Kangert. It sdoesn't look like anyone can follow him.
3km - Cappechi (Movistar) has 13 seconds on Weening and 30 seconds on the Nibali group.
3km - Nibali sits second in the group of favourites which still includes Uran and Evans.
4km - We are less than 1km from a world of pain for all of these riders as Cappechi continues to lead.
5km - These riders have over 30 seconds on the bunch of favourites but they are all over the road. Robert Kizerlowski has joined Atapuma behind the leading trio.
5km - Cappechi has left Brambilla and Weening as the roads snake up the Tre Cime di Lavaredo.
6km - Pirazzi is back on the attack again with Atapuma. They are ahead of the bunch and have just passed Pavel Brutt, and are chasing hard to try and catch the three leaders. Cappechi, Brambilla and Weening are in a lot of pain and the hard riding has yet to start.
8lm - Capecchi doesn't hang around and decideds to push on through the snow, but he is not getting rid of Weening and Brambilla that easily. It's horrible as they start the climb.
9km - Brutt is caught by the little group of Brambilla, Weening and Capecchi as Pirrazi seems to have disappeared.
11km - Brutt is still up front on his own and is about to his the foot of the final climb of the Tre Cime di Lavaredo. Behind him Weening and Brambilla (Omega Pharma Quick Step) have come together and they are also being closely followed by Eros Capecchi (Movistar).
13km - Brutt goes over the Passo Tre Croci first with a 26 second advantage over Peter Weening and Pirrazi third. There is now a few kilometres of a descent before we hit for the final climb.
14km - Pirrazi attacks again towards the top of the climb. Presumably to gain some points, but his lead is unassailable so unless he's short of a few pounds there isn't much need.
15km - Betancur changed his bike and not just a rear wheel change and that is what held him back and put him in difficulty. In the bunch of favourites Saxo Tinkoff drive on to put Betancur under pressure and pull Majka up the climb.
15km - Atapuma seems to have distanced himself from Pirrazi and goes past the remnants of the breakaway riders. Weening (Orica GreenEdge) continues to eat up the time on Brutt and is less than a minute behind our leader on the road now. Weening is working hard, but Brutt is looking spent.
16km - Weening goes past Ermeti who is coming back to the group. Pavel Brutt up front still has 1' 12" on Weening.
16km - Mountain jersey holder Stefano Pirazzi has gone on the attack and is joined by Atapuma (Columbia). They gained a few seconds fairly easily, but we've seen in this Giro that Pirazzi's attacks can be quite erratic.
18km - Our orange friends are back on the front again and the Maglia Rosa is very comfortable as at the front Weening drives on. He has 30 seconds. At the back the word is that Betancur has lost over a minute on the bunch. That would destroy his chances to wrestle the white jersey from Rafal Majka (Saxo Tinkoff). Pavel Brutt (Katusha) still has 2 minutes on the bunch.
19km - Pieter Weening is pushing on alone up the Tre Croci. He is of no danger on GC so he wil be let away to a point. But not the main bunch is whittled down to about 30 riders.
20km - The attacks are coming on the front now as we are on the Passo Tre Croci. Orica GreenEdge (Weening) and Blanco both send riders up the road.
20km - The four leaders are splitting up now and Pavel Brutt (Katusha) has gone up the road on his own. They had two and a half minutes over the bunch but this matters little now that they have stopped working together. Behind them Evans has moved to the front with Nibali in his wheel.
22km - Cavendish fights through the Cannondale team to get to the front and ensure he takes the final two points at the sprint. He will now disappear off the back as his work is done for the day.
22km - Our four leaders go through the intermediate sprint at Dobbiaco and sweep up the majority of the points. Popovych jumped the other three to take maximum points. We will have to wait and see if Cavendish can take the last two and give himself some breathing space in the red jersey classification. Meanwhile Carlos Betancur (AG2R) is being paced back on to the bunch after a problem.
25km - We are descending slightly as we hit towards the foot of the Passo Tre Croci. We still have the slight matter of the intermediate sprint to come before we begin climbing and Cavendish is still lurking around the head of affairs.
30km - Grega Bole (Vacansoleil) has been forced to retire.
35km - The best placed of our four lead riders is still over two hours down on GC and no threat to the riders behind so they are not going to bring them back too quickly, however, their advantage is being whittled away slowly. It's now down to 3' 10". On the front of the bunch the Cannondale team have replaced the Euskaltel team and things are about to get serious.
14:43 - For any of your just coming to us now, we apologise for a lack of graphic at the top of this feed. Due to the changes in the route we are unable to provide one. But don't worry, we will keep you right up to date as we head for the high mountains.
35km - The peloton has changed from the long line it has been all day and the front is turning into a group of favourites and their teams. They are still letting Euskaltel do the work on the front, but it won't be long until this bunch is split between those who have an interest in climbing and those who don't. The four up front are holding a lead of 3' 42".
40km - There is snow everywhere you look now and the riders are putting on gloves and arm warmers. Though they will be making a serious effort during the climbs, the temperatures are close to zero and it is not comfortable weather for cycling in.
45km - Cavendish is determined to prove me wrong today as he sits in behind the orange train in order to stay up front for the next sprint. He's become a very strong overall rider since his stint at Sky last year and is well able to stay at the head of affairs for long periods.
48km - Euskaltel continue on the front, but now there only two riders and they have been joined by some of the Columbia riders. The gap up front is now at 5' 04" and with the next intermediate sprint coming just before the first climb of the day we will not see Mark Cavendish contesting that one.
49km - At the finish line there's a man in a wheelcbair powering his way up the climb through the snow and the fog. A real tough man. The weather up there has changed and now in place of the heavy snow, there is fog.
50km - So I was wrong, Cavendish finds a bit more puff and gets to the front to take the remaining two points at the intermediate sprint point and extend his lead over Evans.
53km - Brutt, Hansen, Popovych and Ermet in that order through first sprint point. The bunch will be coming through in a few minutes. With two points for fifth place does Cavendish have the legs and will Cadel challenge him for those points?
55km - Our four riders out front are doing a very impressive job. They've continued to work hard and have been doing so for over two hours now. The gap is still 5' 35" but despite all the work being done by Euskaltel they are not making major inroads.
60km - We are approaching the first sprint point for the day at Dobbiaco and it's apparent that not only will Mark Cavendish not contest it, but it seems that the breakaway will take the major points with the orange train mopping up the rest. The gap to the leaders is now 5' 52".
65km - There have been one of two riders interrupting the orange line at the front, but without anyone there for any great length of time. At present there is an AG2R rider in there. They will be looking to support Betancur later on today as he battles for the Young Rider jersey. There are only two seconds between himself and Rafael Majka (Saxo Tinkoff).
70km - The breakaway riders did in fact gain some time when the peloton slowed up during the feed zone and the gap is now at 7 minutes. The pace is still being driven along by Euskaltel.
75km - So to recap, our four leaders are still away on their own with a 6' 36" gap. The four are Australian Adam Hansen (Lotto Belisol), Pavel Brutt (Katusha) from Russia, Yaroslav Popovych (Radioshack Leopard) from Ukraine, and Italian Giairo Ermeti (Androni Giacottli).
80km - The Euskaltel chase on the front has irked Nibali and his Astana team mates. Not sure at this stage what the issue is, but there seems to be some tension among the riders towards the front of the group. Meanwhile, Mark Cavendish seems to be struggling with the pace and is languishing down the back of the bunch with a grimace on his face.
85km - The bunch still have 5' 45" out front and they flew through the feed zone disinterested in taking a musette. They will have calculated that they can gain a few extra seconds as the bunch slow up a bit to eat.
13:21 - For those of you used to following the graphic on the top of this feed to see where we are in the stage, we apologise that it's not available today due to route changes. However, we hope you are enjoying our live comments and that you will stick with us right to the finish.
85km - That first climb, the Passo Tre Croci comes at just over 23km from the finish. A category 2 climb with a gradient of 7% and 8km in length it will warm the legs up for the final challenge. After 7km of a slight descent, the riders will hit the last climb of the Giro, the ascent of the Tre Cime di Lavaredo. The first kilometre of this climb has sections of 18% gradient and in the final two kilometres there are sections of 20%.
90km - We'll be passing through the feed zone shortly and the riders may take this opportunity to cover up a bit. The weather will begin to get colder and between here and the first climb we have the two intermediate sprint points so things may get hectic. The gap now is just over 6 minutes.
95km - Interestingly, though Euskaltel only have four riders drilling it on the front of the bunch, they have been one of the few teams to be largely unaffected by withdrawls. They did lose one rider, but still have eight riders in the race. Only four teams still have their full compliment, those being Cannondale, Lotto Belisol, Movistar and Vacansoleil.
105km - At the halfway mark the gap has dropped below seven minutes and the road has begun the gradual rise. The gradient will continue to intensify right up to our first climb of the day, the Passo Tre Croci at in about 90km.
12:48 - Adam Hansen is a serious strong man and all round gutsy rider. He may not stay out until the finish today, but he's certainly not shy about giving it a go. Who is your rider of the Giro so far and why?
105km - Interestingly Adam Hansen (Lotto Belisol) is wearing a skin suit today. I'm sure he has no intention of sprinting at any stage so maybe he's just run out of clean clothes. He is also wearing shoes he made himself. Fabircated from superlight carbon they have served him well thus far. Their gap is no 7' 03". Coming down slightly.
110km - Sky lead the team standings with Movistar in second place. Sky could be well placed on the final climbs of the day should Rigoberto Uran have a good stage. The Columbian currently stands in third overall at 4' 12" behind Vincenzo Nibali.
115km - The gap still sits at 7' 28" as four Euskaltel riders continue to line out the bunch and put everyone under pressure. No idea why they are doing this, but I'm sure it will become apparent as te stage unfolds. The average speed so far is 46km/h.
120km - We have some sun out on the road. A novelty for this Giro. It's been wet and cold on the majority of days and it has taken its toll on riders. Meanwhile it's still snowing fairly heavily at the finish and still -3 degrees.
125km - As the Euskatel team continue to drive on at the front of the bunch, the red jersey of Cavendish is sitting back down the bunch. Vincenzo Nibali is also only 10 points down on Cavendish so assuming Evans and Nibali do battle for stage honours today, Cavendish may well lose the jersey today, but he will be confident that he can wrestle it back tomorrow.
130km - There's plenty of shuffling going on within the peloton and after a brief appearance, Omega Pharma Quick Step have been nudged off the front and replaced by Euskaltel Euskadi with Astana following closely behind.
135km - To recap, the break is made up of Adam Hansen (Lotto Belisol), Pavel Brutt (Katusha(, Yaroslav Popovych (Radioshack Leopard) and Giairo Emerti (Androni Giocattoli). Their gap is 6' 40".
140km - Omega Pharma Quick Step come to the front of the peloton to take some control as the gap draws out to 8.16 for the four leaders. Mark Cavendish is obviously interested in collecting a few more points towards his red jersey today. He is aiming to make it a full house having already won the points classification in the two other Grand Tours.
150km - The weather on the road is realtively warm and dry at the moment as the breakway discuss tactics. The final climb today is a torturous 12.4 per cent average climb with spots where it hits 18 per cent. This will be a leg burner and with the combination of difficult terrain and the terrible weather there may be huge gaps as riders cross the finish line.
155km - Euskaltel have decided to show themselves at the front of the bunch and bring some urgency to proceedings, but it will take some chasing to close down the gap of six minutes while the breakaway are still full of energy.
160km - The road begins to rise from about halfway through this stage and it will be really energy sapping for such a small group to stay away until the end. At the finish it's -3 degrees and almost a white-out so let's hope that they all get there in one piece.
11:29 - Correction: The group of four is Hansen (Lotto Belisol), Brutt (Katusha), Yaroslav Popovych (Radioshack Leopard), and Emeti (Androni Giocattoli). Their gap is now nearly 6 minutes.
165km - The lead is still growing out for the quartet up front as they are now 2.35 clear. This bodes well for an exciting finish as the GC contenders will not be over exerting themselves too early in the stage.
11:19 - The change of route has left us without a progress bar at the top of this feed. Apologies for this, but we will keep you right up to date with all the action as it happens.
170km - The escapees have extended their lead to 1.15. The best placed of these riders is Australian Hansen who is over two hours behind Nibali. Their ambition will be to gain some much needed air time for their sponsors and try and hang out there as long as possible. Though you never know, with rain forecast along the route and snow at the finish, maybe they just want to get off their bikes as quickly as possible.
175km - With 35km of racing done, a break is developing. It includes Stage 7 winner Adam Hansen (Lotto Belisol), Pavel Brutt (Katusha), Giairo Emeti (Androni Giacattoli) and Jens Mouris (Orica GreenEdge). They have 55 seconds on the bunch.
180km - Mark Cavendish (Omega Pharma Quick Step) is holding on the red points jersey by a slender 4 points. His nearest challenger is Cadel Evans (BMC), although I would doubt he will be focused on collecting points today, the intermediate sprints come at 156km and again at 187.9km, a point when Evans will be up front keeping himself out of trouble and in the mix. It may mean that the Manx Missile has to pick up a few points tomorrow to get his hands on the red jersey.
180km - The battle for the Maglia Rosa looks set to come down to the final climb today on the Tre Cime Di Lavaredo. Vincenzo Nibali (Astana) has a 4.02 cushion over Cadel Evans (BMC) and Rigoberto Uran (Sky) is a 4.12. Next in line is Michele Scarponi (Lampre-Merida), but at 5.12 down he will be looking to cement his fourth spot.
190km - 169 riders left the start this morning in Silandro. We lost Robert Gesink (Blanco) yesterday. He wasn't in good form in the time trial on Thursday and decided to call it a day. Also absent is of course the aforementioned Di Luca.
200km - The route for today looks like this. We've lost the climbs of the Passo Costalunga, Passo San Pellegrino and the Passo Giau, but the last 20km of the race should still be enough to decide the winner of the Maglia Rosa for 2013.
205km - Following Vincenzo Nibali's dominance in the TT on Thursday, there is now a gap of over 4 minutes between himself and his nearest rival BMC's Cadel Evans. Unless he cracks today the Maglia Rosa would seem to be his. However, the white jersey is still up for grabs in what is turning out to be quite the contest between Saxo-Tinkoff's Rafal Majka and AG2R's Carlos Betancur. There are only two seconds between them on GC so expect fireworks today.
210km - As the riders roll out from the start in Silandro, the news from atop the Tre Cime Di Lavaredo is that the snow, which had abated, has begun to fall again. It is falling quite heavily at the moment, but race technical director Mauro Vegni was adamant yesterday that the race will reach the intended finish line today regardless of the weather. So here goes...
10.20 - During yesterday's enforced rest day, the news broke of now ex-Vini-Fantini rider Danilo Di Luca's positive test for EPO. Read what Blazin' Saddles has to say on the matter here.
10.10 - The cancellation of Stage 19 and the rerouting of Stage 20 means that the final climb of the day will be the Cima Coppi (the highest altitude of the race). This climb is one of the two that remain on the Stage 20 profile and both come in the final 20km.
10.00 - Welcome to LIVE coverage of Stage 20 of the 2013 Giro d'Italia. Following the cancellation of Stage 19 yesterday due to bad weather, today's stage has also been hit and today the riders will ride an ammended 210km route from Silandro to a mountain top finish at Tre Cime di Lavaredo.
