So, after that wobble on the Umbrailpass, Tom Dumoulin retains his maglia rosa, but sees his lead slash to 31 seconds on Nairo Quintana, while stage 16 winner Vincenzo Nibali rises to third place at 1:12. Game on!

Confirmation of the top ten from an enthralling stage on the Giro...
Mikel Landa came so close to opening up Team Sky's account but was left ruing his luck as he slammed the handlebars twice after Nibali pickpocketed him over the line.
Brilliant by Tom Dumoulin, who comes home 2:18 down to retain the maglia rosa after his very big scare today.
Formolo must have broke clear on the descent because the Italian takes sixth place by a large gap before the Jungels, Yates, Mollema and Pinot group comes home.
Quintana takes third place, then Pozzovivo comes home for fourth. Then we have Zakarin - all in quick succession.
Nibali sits on Landa's wheel as they negotiate the final bends... and it's a fierce sprint in slow motion... but Vincenzo Nibali takes it by a whisker!
Landa is leading it out with Nibali in his wheel...
Under the flamme rouge and we're into the final kilometre.
The leaders enter Bormio and it's Landa driving the pace. He deserves the win after all the attacking he did from the break, but Nibali has played this one really well.
Quintana is closing in on Landa and Nibali now that most of the technical stuff of this descent is over. Zakarin has passed Pozzovivo, I think, behind. Dumoulin looks to be suffering from cramps.
Five clicks until this... and Dumoulin is dropping back - the latest gap is three minutes for the Dutchman.
Kruijswijk and Hirt are with the Pinot and Jungels chase group, with Formolo and Yates. Zakarin is a bit further ahead, behind Pozzovivo, Quintana, and then the two leaders, Landa and Nibali.
More heart-in-mouth moments for Nibali as he skids on a corner. Not holding back, is he? Pozzovivo has been dropped by Quintana - no surprise when you remember that crash he had a few years ago, which almost ended his career, if not life. Landa, meanwhile, is keeping up with Nibali. They lead the chasing group of Jungels etc by 1:25.
What Dumoulin can't do now is push things too much - it's far more important for him to get to the bottom in one piece, rather than try and save a few seconds and come a cropper. He's probably really weak following his illness and he may be a bit dozy, too.
Dumoulin is rallying. He's 2:15 down on the leaders, but making some inroads on Quintana. At this rate, he'll still be in pink today despite his big scare.
Nibali is almost on Landa's wheel now. Could he win the host nation's first stage in this race? This could kick-start his Giro. And he's not holding back: the Shark has just bunny-hopped over some water flowing across the road - just ahead of a hairpin bend...
Landa's lead is getting slimmer and slimmer... he'll be caught by Nibali soon, with Quintana right behind.
Here comes Dumoulin, who goes over the top 2:18 down on Landa - so that's about 2:10 down on Quintana. He can afford to lose another 30 seconds - not factoring in bonus seconds at the finish - if he wants to keep the pink jersey. This descent will be key.
Zakarin has joined Nibali and Quintana on the descent. They trail Landa by eight seconds.
Over the top goes Mikel Landa, who will take maximim KOM points that could put him in the maglia azzurra reckoning. But can he hold on once the road goes downhill to Bormio and win the stage?
Nibali's acceleration has seen Landa's gap drop to 20 seconds...
Attack by Nibali! Quintana can close it, but Zakarin and Pozzovivo have dropped back a bit.
Jan Hirt has been caught - and will now struggle to hold on. Landa continues his potentially winning ride - he's 45 seconds ahead of the chasers. Kruijswijk has been caught by Jungels, Pinot, Mollema and Yates, I think it is.
Nibali looks much better than he has been so far in this race. This quartet have Jan Hirt in their sights - he should be caught before the summit.
Kruijswijk is suffering from his earlier efforts - the Dutchman can't stay with the Quintana group. He looked to be rising up the standings today, but instead will drop.
Kruijswijk is caught by the Quintana quartet, which is now a quintet. They're one minute down on Landa, but 1:40 ahead of Dumoulin now, who has just caught Cataldo.
Landa grimaces as he grapples with the steep 9% section near the summit. He has about 3km left to ride before the long descent. We don't have time checks back to Hirt and Kruijswijk, but they haven't been caught by Quintana's group yet.
Formolo, Mollema, Pinot, Yates and Jungels are in a second chasing group, about 20 seconds down on the Quintana-Nibali group and one minute ahead of lone ranger Dumoulin.
We're back into the snow fields now as Nibali flicks an elbow to get Zakarin to come through. Pozzovivo and Quintana are there too. They trail Landa by 1:05. Meanwhile, Dumoulin continues his resurgence. He's passed Pellizotti but is still 2:22 down on Landa. He's still in the virtual maglia rosa - as well as the real one, albeit a bit browned on the edges - but it's been a day to forget for the Dutchman.
Another attack from Nibali - and Quintana, Pozzovivo and Zakarin are the only riders who can follow. Formolo and Pinot leads a chasing group.
ATTACK: Nibali makes the first move and the first casualty is Bob Jungels, who is dropped. The group splits and then comes back together again. Further back, Dumoulin - who is within one minute now - takes on some gels from his team car.
Shortly after Kruijswijk cracks, Landa attacks Hirt to open up a gap on the front. Back with the main pack and Pellizotti has been dropped, with Cataldo struggling...
In this main pack we're down to Quintana, Amador, Nibali, Pellizotti, Pozzovivo, Mollema, Zakarin, Pinot, Jungels, Yates, Cataldo and Formolo. They trail the three leaders by one minute.
Kruijswijk, Landa and Hirt are still together on this climb with a lead of 1:20 over the 15-man chasing group, which includes all the big favourites except that man Tom Dumoulin, who had the runs at the start of this climb and needed to stop on the side of the road for a natural break. He's still a further 1:20 behind, and very isolated.
To rub salt into the wounds, Movistar's Izaguirre is sandbagging Dumoulin as he continues trying to slash his losses. The Dutchman, who looks white as a sheet, is 1:18 down on the others. Meanwhile, Igor Anton is the latest of the escapees to be caught by the main pack - or will be, in a minute.
Pellizotti is on the front pacing for Bahrain Merida leader Nibali, with Quintana and Anacona - who has been caught - just behind for Movistar. They have Amador too - he's just been caught. They're stuck between a rock and a hard place: Dumoulin showed much fair play yesterday when Quintana attacked, but they're clearly not too worried about showing the same kind of gesture of goodwill...
In all that excitement, I forgot to announce that we're onto the final climb of the day, the Cat.1 Umbrailpass (13.5km at 8.4%).
Terrible luck for Tom Dumoulin - he's now on his own, riding alongside an ambulance, and he's 1:20 behind the main pack, that includes Nairo Quintana. Ilnur Zakarin had put in a little attack, but he was reeled in quickly.
It's not often that you see cyclists do a Paula Radcliffe, but Dumoulin has done just that. He's back on his bike and has Laurens ten Dam to help pace him back. But it remains to be seen how he reacts from that.
OH NO! Tom Dumoulin stops on the side of the road, tears his jersey off, rips down his bib shorts - and yes, does what you think he does! Luckily the camera pans away, but he's having a stinker out there...
They're onto the small rise to Santa Maria Val Mustair ahead of the Umbrailpass proper. WIth the gap going down to 1:40 this break has fractured. Kruijswijk and Landa have ridden clear, with Amador and Hirt in pursuit. Further back we have Anacona and Anton.
Over the border they go - and we're now officially in Switzerland. It's the first time the Giro100 has left Italian soil - and we have a break of six riders carrying a lead of two minutes ahead of the final climb. They are: Mikel Landa (Team Sky), Winner Anacona and Andrey Amador (Movistar), Jan Hirt (CCC Sprandi Polkowice), Steven Kruijswijk (LottoNL-Jumbo) and Igor Anton (Dimension Data).
Cataldo comes to the front and remonstrates with Plaza, who is driving an infernal pace. He gesticulates wildly, something along the lines of "What the hell are you doing?" but the Spaniard flicks a wrist and shouts back, along the lines of "Mind you own business, wise guy".
The gap is coming down quite quickly under the pace-setting of Orica-Scott and Katusha-Alpecin back in the pack. Amador is no longer in fourth place in the virtual standings, dropping to fifth as the gap comes down to 2:15. It's worth remembering that they've already been racing for more than five hours - and we have another hour at least, probably a bit more, say 13 minutes more. I reckon a finish at around 17:00 CET.
Deignan is done for the day: the Irishman hits the wall - just as Kiryienka did earlier. So Landa has burned all his matches and now must do it alone. The road is still rising as the riders approach the Swiss border. The main pack has returned to within 2:35 of the six leaders.
Orica-Scott have Ruben Plaza on the front of the main pack now, with Adam Yates a bit further back in the group. There are loads of pairs out there: Cataldo and Sanchez are there for Astana, while Bahrain Merida have Nibali and Pellizotti. Movistar are taking a breather - probably because Dumoulin is off the back with his Sunweb team car. The calm before the storm. Katusha-Alpecin send one of their riders to the front to help lead the chase for their man Ilnur Zakarin, whose position is under threat from both Amador and Kruijswijk in the lead group, which has 3:10 to play with.
There's no flurry from the break for the intermediate sprint - despite six bonus seconds being up for grabs. It's the Sky duo who go over ahead of Anton and the others.
Laurens ten Dam is back with the main field and riding alongside his Sunweb leader, Tom Dumoulin, the man in pink who, so far today, has passed this test with flying colours. Meanwhile, Amador and Landa are back with the other five leaders, so we have seven out ahead - and the gap is 3:07. Deignan and Landa for Sky, Anacona and Amador for Movistar, Hirt for CCC, Kruijswijk for LottoNL-Jumbo and Anton for Dimension-Data.
It's fair to say that the scenery around these parts is pretty spectacular...
Pierre Rolland has been caught by the main pack. The Frenchman has never been a renowned descender and so that's no huge surprise. Most of the riders are taking off their jackets ahead of the final climb. Gorka Izaguirre, who was with the leading group, is now back with the main pack and alongside his team-mate Quintana.
The two leaders have 35 seconds on the chasers and 2:45 over the maglia rosa group. So as it stands, Amador is up to fourth place on GC and above Nibali in the virtual standings.
Amador reaches to his back pocket and liberates a gel. He and Landa have reached the bottom of the descent and will soon start the false flat ahead of the second intermediate sprint. There are then two little peaks before the final climb, the Umbrailpass, which itself is followed by a long 20km descent to Bormio.
Kruijswijk, Anacona, Hirt, Anton and Deignan are in a five-man chase group behind leaders Amador and Landa. They still have round 2:30 over the main pack and around 25 seconds on the chasers.
Landa has dropped Kruijsijk and now caught Amador on this descent. Earlier we saw the Movistar man skid a little on one of the tight bends, so perhaps he's taken his foot off the gas a little.
Kruijswijk leads the chase ahead of Landa. The Rolland group is at 1:38 and the main pack at 2:10. This is a hair-raising descent, to be fair.
Rui Costa is about to be caught by the main field, which is being led by Bob Jungels and Carlos Verona of Quick-Step Floors. Because of the multitude of bends, it's hard to get up a lot of speed on this descent. But Amador is doing his best effort - the Costa Rican has opened up a little gap over the other leaders, who have already caught Landa on the descent.
Rolland, ten Dam and Foliforov ride in a three-man chase group 1:30 behind the nine leaders as they edge down the first of these 48 hairpin bends extremely gingerly. That's primarily because they're very steep and tight, but also because the road surface is pretty shocking - all cracked and potholed from the freezing water and melting snow.
Here's the moment Landa won the Cima Coppi.
Mikel Landa crests the summit to take the Cima Coppi prize at the top of the Passo dello Stelvio.
Igor Anton and Mikel Landa - former Euskaltel team-mates a long time ago - open up a small gap near the summit. It's the Team Sky rider, who is wearing a jacket and gilet, who jumps clear in pursuit of the KOM points. Anton can't keep up with him, while Sanchez is a bit further back and ahead of the other escapees.
Chapeau, Winner! Anacona manages to rejoin the leaders just ahead of the summit - so Movistar now have three in this leading group of nine. Options.
Dario Cataldo, the last man to crest the summit of the Stelvio in pole position - back in 2014 during a stage won by Quintana - is still with the main favourites. Nibali, Pinot, Jungels, Pozzovivo, Zakarin, Mollema, Yates, Formolo - they're all here with Quintana and Dumoulin.
Will anyone attack before the summit or will they keep everything for the two descents and the final ascent? The eight leaders are still being driven by Deignan, Landa and Sanchez. They have 17 seconds on Anacona and 2:12 on the main pack. Dumoulin puts on a gilet - with a bit of help from Zakarin - and still looks in control.
Little attack by Tejay Van Garderen of BMC - although he's only out long enough to reel in Sebastian Henao, who was in the break, before the Trek-led pack reel him in again. That was the first time we've seen the American go forward - and not backwards - in this race, more or less.
Omar Fraile, the maglia azzurra, has been caught and past by the pink jersey group. The Spaniard will be hoping that neither Dumoulin nor Quintana, or even Zakarin for that matter, win today's stage because they're all close to his points tally in the KOM standings.
Mendez, Costa, ten Dam, Grosschartner, Rolland and Dombroswki ride in the chasing group from which Anacona has just attacked. They're about a minute down on the leaders, who are being driven by Deignan and Sanchez.
The first signs of snow on the side of the road... Meanwhile, Anacona has pushed on from that chasing group, dropping around six riders who he was with. Quite odd to see him push on rather than wait for Quintana - perhaps the plan is going to be put into place later on, hence the quick rethink by the Movistar DS, who drives up alongside Anacona for a chat.
The eight leaders are: Amador, Izaguirre, Kruijswijk, Landa, Deignan, Sanchez, Anton and Hirt. They have 2:25 over the pack with a chasing group being led by Anacona about 45 seconds down. Rolland and Fraile were with the leaders but have been distanced a little.
Flashpoint: Bauke Mollema and then Tom Dumoulin both lash out at a Colombian fan who appears to have given Nairo Quintana a little push...
Lots of riders being shelled out of both the leading group and the main pack - including ten Dam, who is perhaps going to drop back to help out Dumoulin. Dombrowski and Anacona appear to have been dropped, too, from the lead group, Mendes too. Fraile is no longer with the leading group of around eight riders...
Bob Jungels, the white jersey, and Tibaut Pinot have come to the front alongside the Trek riders. Sunweb have dropped back, including the maglia rosa, who is now quite a bit back in the main pack. Is Dumoulin bluffing or is this the day his race starts to unravel? He has no more team-mates now after Geschke dropped back. Just ten Dam out ahead in the break.
That's it - Kiryienka has finally hit the wall after his infernal pace-setting duties for his Sky team-mates Landa, Deignan and Henao, who are all in the break. Meanwhile, back with the main pack, it's now the Trek-Segafredo team of Bauke Mollema - sixth on GC at 4:32 - who are driving the pace.
Vincenzo Nibali has lost a key mountain domestique as Bahrain Merida's Kanstantsin Siutsou is dropped, alongside Matteo Montaguti of Ag2R-La Mondiale, from the main pack.
Vasil Kiryienka, with his Team Sky jersey open and flapping in the wind, still leads the break with Natnael Berhane of Dimension Data just behind. Numerous riders have popped and been dropped by the leading group. Back with the pack, which rides 2:40 behind, Sunweb have four men on the front, with Priedler, Geschke and Haga ahead of Dumoulin in pink, who has five Movistar riders behind (including Quintana). While Dumoulin has one rider in the break - Laurens ten Dam - Movistar have three: Jose Herrada, Andrey Amador and Gorka Izaguirre. In fact, the only Movistar rider not present either in the break or behind is Daniele Bennati, who did his job earlier in the day by forcing himself into the break before the Mortirolo.
A little reminder of what the Stelvio looks like for the uninitiated...
Groups have come over the line in drips and drabs - with the latest gruppetto being led over the line by a Cannondale rider who can't resist having a joke at Luka Pibernik's expense, around 10 minutes down on the peloton...
Right, it's show time. The riders are onto the Cat.1 Passo dello Stelvio (21.7km, 7.3% average, 12% maximum). Europe's second highest paved pass is the Cima Coppi of the race and it's been tackled by the south side - which means the riders will then negotiate the famous 48 hairpin bends down to Prato before the final climb of the day, which is back up the Stelvio via the lesser known third pass, the Umbrailpass. With Bormio lying at 1209m above sea level and the summit of the Stelvio at 2758m that means we have more than 1.5km of vertical gain ahead.
Five Sunweb riders - including the maglia rosa, Dumoulin - and Peter Stetina of Trek Segafredo lead the streamlined peloton through the finish 2:53 down on the leaders ahead of the double ascent. The first climb of the Stelvio will be the Cima Coppi of this year's race being the highest mountain pass.
The break is led over the finish line ahead of this terrible extra loop, which includes a double ascent of the Stelvio. It's that man Kiryienka who leads them over the line - not Luka Pibernek thinking he's already won. The gap is up to 2:50 for these escapees - and there's no bell ringing; that would be cruel, given what's to come.
Kiryienka still drives this break of 26 riders, whose lead is up to 2:02 on the approach to Bormio, where the stage will finish - but in another 100km time after the most brutal of out-and-back loops. We're hearing that Carlos Verona of Quick-Step Floors is also in this break - which makes sense, because previously we gave a list of 25 riders.
It's sunny today in the Alps but the temperature at the top of the Stelvio - which is still covered in snow - is just 5 degrees Celsius. That will take its toll on the riders - especially when they go down.
Vasil Kiryienka is riding a hard tempo on this false flat in the valley - the Belarusian is clearly Team Sky's expendable man in this break. Once he pops he will have hoped to have reduced the leading group considerably. The plan will be then for Landa to use both Henao and Deignan as climbing domestiques before riding to victory. Well, at least that looks to be the plan. Although Movistar with have other ideas: their plan will be for Quintana at some point to bridge over to this leading group and relay with Amador, Herrada and Izaguirre...
A reminder that Luis Leon Sanchez crested the summit of the Passo del Mortirolo to pick up the Cipo Scarponi in memory of his late Astana team-mate, Michele Scarponi.
Many riders from the break have taken on musettes at the small town of Le Prese. They're not at the official feed zone - which is just ahead of Bormio - but it will be important to keep refuelling today. The road gradually climbs uphill to Bormio ahead of a slight drop before the first of two ascents of the Stelvio.
Tom Dumoulin, the maglia rosa, has Preidler, Haga and Geschke with him in this reduced peloton, which trails the leaders by 1:55. We're hearing of a third withdrawal of the day: after Elissonde and Hermans, we have Sean de Bie of Lotto Soudal who has thrown in the towel.
So, there are some dangermen in this break who could jump up the overall standings if this group stays out: both Amador and Kruijswijk are in the top ten at 6:01 and 7:03 from the summit respectively. There are also some very tidy climbers in the shape of Landa, Sanchez, Anton, Fraile, Rolland, Dombrowski, Woods, Foliforov...
So, here's the updated list of leaders: Jose Herrada, Andrey Amador and Gorka Izaguirre (Movistar), Laurens ten Dam (Team Sunweb), Steven Kruijswijk (LottoNL-Jumbo), Mikel Landa, Sebastian Henao, Vasil Kiryienka and Philip Deignan (Team Sky), Luis Leon Sanchez and Pello Bilbao (Astana), Omar Fraile, Natnael Berhane and Igor Anton (Dimension Data), Pierre Rolland, Joe Dombrowski and Michael Woods (Cannondale-Drapac), Rui Costa and Edward Ravisi (UAE Team Emirates), Laurens de Plus (Quick-Step Floors), Jose Mendes (Bora-Hansgrohe), Manuel Senni (BMC), Alexander Foliforov (Gazprom-Rusvelo), Jan Hirt and Felix Grosschartner (CCC Sprandi Polkowice).
Another withdrawal to report on is Ben Hermans of BMC, who fell sick on the rest day. That's a blow for the Belgian, who was sitting in 15th place on GC at 10:51 behind Dumoulin. Following Rohan Dennis' withdrawal in the opening week, and Tejay Van Garderen's imposion, Hermans was BMC man for the GC.
Team Sky don't only have Landa in this break, they also boast Philip Deignan, Sebastian Henao and Vasil Kiryienka. But there's no place on the race anymore for Kenny Elissonde, the Frenchman, who joined Geraint Thomas by withdrawing from this 100th edition of the Giro. He crashed badly on stage 15 and has been suffering accordingly.
The peloton - led by Dumoulin's Sunweb team - went over the summit around 1:40 down on the leaders. Gorka Izaguirre, who won a stage in the second week of the race, is also in that break for Movistar alongside team-mates Herrada and Amador, so that's quite a coup for Quintana.
Here's the moment as Sanchez took maximum points over the top ahead of a sporting Fraile and Landa.
Lovely scenes at the to of the Passo del Mortirolo as Omar Fraile lets Luis Leon Sanchez take maximum points over the top. Now, he didn't need to do that because those KOM points could have been very important to Fraile in his quest to win the maglia azzurra, but his sense of decency and fair-play shone bright - and he pats his compatriot on the back after Sanchez remembered the memory of Scarponi. A nice touch, there.
It's hard to tell at the moment who exactly is in this leading group because many of the original escapees were swept up and many others went clear with Sanchez and Fraile at the start of the climb. We're hearing that Movistar have both Andre Amador and Jose Herrada in this break - if true, that would be a coup for Quintana, for they are strong climbers. We're nearing the summit now. Mikel Landa of Team Sky is also in this group.
Luis Leon Sanchez's motivation is clear: this climb has been branded the Cipo Scarponi - the Scarponi prize - this year in memory of the late Michele Scarponi, Sanchez's Astana team-mate who was tragically killed in a training accident two weeks before the race. Scarponi attacked on the Mortirolo in the 2010 Giro d'Italia en route to winning at Aprica, so it's a fitting tribute - and what better way for Sanchez to remember his friend by cresting the summit in pole position before winning the queen stage of the race...
Tom Dumoulin, the maglia rosa, has two Sunweb team-mates - Preidler and Geschke - on the front of the peloton with him, ahead of three Movistar riders (including Quintana).
The break - which has shed some riders - is only 1:18 ahead of the pack, and has been joined by some fresh faces, most notably Luis Leon Sanchez (Astana) and Omar Fraile (Dimension Data). Fraile's motivation is clear: he wants as many KOM points as possible so he can move back into the lead in the maglia azzurra standings.
A reminder that we're on the Passo del Mortirolo (Cat.1, 12.6km, 7.7% average, 16% maximim). It's worth adding that they're not climbing the harder side - that's reserved for the descent - but this is still a brutal slog for the riders, especially ahead of two ascents of the Stelvio.
Interestingly, Dumoulin and Quintana both have two team-mates in the break... one of Quintana's Movistar men, Bennati, won the intermediate sprint at Malonna ahead of the climb. That man Anacona will be a very useful relay later on for the Colombian.
The names of the 27 riders in the break are Quentin Jauregui (Ag2R-La Mondiale), Pello Bilbao and Zhandros Bizhigitov (Astana), Manuel Senni (BMC), Joe Dombrowski and Davide Villella (Cannondale-Drapac), Felix Grosscharnter and Branislau Samoilau (CCC Sprandi Polkowice), Matthieu Ladagnaous (FDJ), Jasper De Buyst (Lotto Soudal), Winner Anacona and Daniele Bennati (Movistar), Laurens De Plus and Pieter Serry (Quick-Step Floors), Nathnael Berhane (Dimension Data), Maxim Belkov and Alberto Losada (Katusha-Alpecin), Jurgen van den Broeck (LottoNL-Jumbo), Vasil Kiryienka (Team Sky), Phil Bauhaus and Chad Haga (Team Sunweb), Mads Pedersen and Jasper Stuyven (Trek Segafredo), Marco Marcato and Matej Mohoric (UAE Team Emirates).
The pace was very high over the first hour of racing with 50km covered ahead of the climb. That tempo will surely take its toll once the riders start going uphill...
We join the stage LIVE with a group of 27 over one minute clear following the opening 70-odd kilometres. They're approaching the first climb of the day, the Passo del Mortirolo.
The riders rolled out of Rovetta around 10:40 CET with the field down to 174 following the third rest day. The sun is out and the temperature is 21 degrees.
And here were the classification leaders at the start of today's stage in Rovetta. So it's Tom Dumoulin in the maglia rosa, Fernando Gaviria in the maglia ciclamino, Omar Fraile in the maglia azzurra (even though he trails Dumoulin by 51 points to 49 in that particular battle), and Bob Jungels in the maglia bianca.
A reminder of that the riders must tackle today: it's the 'easy' side of the Mortirolo followed by a double ascent of the snow-capped Stelvio, including the never-done-before Umbrail pass ahead of a fast descent to the finish in Bormio. There's 5,400 metres of climbing in total - hence the five-star status...
So, Dutchman Tom Dumoulin is sitting pretty on the top of the standings - and still has that 27.6km final day time trial into Milan to look forward to. But before then he must weather the high-mountain storm, starting with today's stage in the Alps, which is followed by Thursday's stage in the Dolomites and then another summit finish on Friday, and Monte Grappa on the penultimate day of the race. In short: it's about to get a whole lot tougher for the maglia rosa. Does he have what it takes? Read my rest day analysis...
Dumoulin (Team Sumweb) crossed the line on the same time in eighth to remain top of the general classification, but his lead over second-placed Quintana was cut to 2min 41sec after the Colombian received six bonus seconds. Pinot is 3min 21sec down in third place, while defending champion Vincenzo Nibali (Bahrain Merida) stays 3min 40sec adrift in fourth after finishing seventh on the day.
Before Monday's rest day, Bob Jungels out-sprinted his fellow general classification contenders to win stage 15 of the Giro d’Italia, as Tom Dumoulin retained the overall lead. A select group of race favourites pulled away from the peloton on a small late climb and arrived together to the finish in Bergamo, where Jungels (Quick-Step Floors) comfortably beat Nairo Quintana (Movistar) into second place and Thibaut Pinot (FDJ.fr) into third.
Hello and welcome to live coverage of the big one: it's double Stelvio day on the Giro d'Italia with the 222km queen stage 16 from Rovetta to Bormio - one that also includes the fearsome Mortirolo. Sit tight, buckle up, and join us for the ride...
