Confirmation that Richie Porte drops out of the top three after that puncture. He lost 47 seconds and is now 1:09 down on race leader Alberto Contador. Spain's Mikel Landa leapfrogs Porte into third place behind his Astana team-mate Fabio Aru.

What a day - the break holds on when it should have been a sure fire sprint, and one of the GC favourites loses a large chunk of time after an inopportune mechanical.
Richie Porte is led over the line by his Sky team-mates after that puncture - and he's 1:05 down on the winner, and will lost more than 35 seconds on his GC rivals.
The peloton is led home by Giacomo Nizzolo (Trek) about 30 seconds down.
Matteo Busato took second place, and local lads Alessandro Malaguti and Alan Marangoni finish third and fourth.
Victory for Nicola Boem of Bardiani-CSF!
Marangoni is tiring... Boem has rounded him...
Alan Marangoni clearly doesn't trust his sprint because he's made his move very early. He has a small gap over the cobbles - but Malaguti who takes the chase up...
They're going to hold on. Incredible scenes. Now it's a question of whether or not it will be a local lad who takes the win. And Marangoni attacks!
Solidarity from his fellow Australian as Michael Matthews joins the Sky train trying to reel Porte back to the pack. In the peloton, riders from the teams of the leading quartet are trying to get on the front to slow the pace.
The peloton is 55 down on the four leaders - and Porte is 35 seconds further back. Drama on the Giro...
Yes, and that was a mechanical issue for Team Sky's Richie Porte - so he needs to fight back on just as the hammer has gone down. It will be interesting to see if that affects Viviani's chances - he'll have to do it all on his own if it comes to a bunch sprint.
Just the one minute now as a rider pings off the front of the pack...
Big sense of urgency now in the peloton - and there are some Sky riders off the back. Is that because Porte or Viviani have been distanced? Interesting...
Still 1:15 for these four Italian tearaways - it will be the biggest day in the careers of all four of these riders were they to defy the peloton and stay out for the win.
If Marangoni comes from nearby the finish, then Malaguti can do one better: the 27-year-old is actually from Forli. So we have two riders looking for a priceless home win. What a story this would be...
Gatto is reeled in and the quartet now have 1:30 over the pack. It's touch and go.
Poor Gatto, he's decided to call it a day and wait until the peloton sweep him up - it was too much of a big ask. And the leaders have lost their most experienced man.
Puncture for Oscar Gatto - heartbreaking for the Italian, who will struggle to fight back on on his own.
No can do for Kung, who is reeled in by the pack. Now Lotto-Soudal, Trek and Giant Alpecin are roaring on all cylinders on the front of the pack.
BMC's Stefan Kung pings off the front in pursuit of the five leaders - and so he might. The peloton has not got its act together and there's a chance this break may stay out.
The second intermediate sprint isn't contested either, with Gatto rolling through in pole position. The gap is down to just above two minutes.
It's still quite well poised with the break holding a lead of 2:30 over the peloton. You'd fancy them to be reeled in ahead of the expected bunch sprint - but you never know, stranger things have happened...
Heinrich Haussler apparently has stomach problems today and has already ruled himself out for the finish - like fellow Aussie Michael Matthews. Looks like all that work from IAM Cycling was completely in vain...
The sprint passes in a blur, with neither the break nor the peloton contesting it. So, it's all in for the finale - unless that second sprint in 16km musters anything up for us supporters.
IAM Cycling have totally disappeared from the race following the retirement of their sprinter Pelucchi. Such a shame - the Italian carried fine form going into the race, but that crash in stage two - caused when a spectator rode into the path of the riders - did for his chances and he's been riding in pain ever since. It remains to be seen if Haussler can get anything from this - but the German-born Australian is not well suited to these flat fast finishes.
Just 3km to go until the first of two intermediate sprints. The five leaders have 2:35 on the pack. Gatto, the only rider with a Giro stage win to his name in this leading group, is riding with a big bandage on his left leg - remnants of a crash in the opening week.
Matteo Pelucchi has just abandoned the Giro - which puts a spanner in the works for IAM Cycling, who were only previously leading the chase. One of their riders can be seen now animatedly takling to Luca Paolini of Katusha - presumably about the turn of events. The Swiss team will have to regroup and put their eggs in the basket marked Haussler now. Pelucchi, it should be added, was the lanterne rouge of the race - riding over two and a half hours down on Alberto Contador after crashing heavily in stage two.
The gap is back up to three minutes now as Lotto-Soudal come to the front of the peloton. A second stage win for Andre Greipel would put the German national champion back into the red points jersey. He trails Elia Viviani by just three points in the competition...
Today's finish is pretty technical - the road is narrow and there are a few twists and turns, plus some cobblestones ahead of the final flat and straight 450m run to the line. Perhaps Tom Boonen (Etixx-QuickStep) may have his say? The Belgian veteran will have an edge over his rivals when it comes to experience and positioning, but he may just not have the brute strength or speed.
The Lotto-Soudal (Greipel) and IAM Cycling (Pelucchi) trains have formed on the front of the peloton, but the pace is still being set by Giant Alpecin, who have one rider setting the tempo. Their man is Luka Mezgec, who has been pretty quiet so far in this race. Perhaps he can reignite his Giro today.
The gap is down to 2:55 for the five leaders - probably because of the first of those two intermediate sprints on the horizon in another 20km.
The final rider in this break is the most feted: 30-year-old Oscar Gatto, a veteran of eight Giros - and a stage winner from 2011, when he pipped Alberto Contador for the win in stage seven at Tropea. The Italian just held off lone chaser Contador, with the peloton looming large. Alessandro Petacchi led the pack over the line just five seconds later. Androni-Sidermec's Gatto has not picked up a win this season, but snared two stages in last year's Tour of Austria.
Nicola Boem has made a name for himself as a Giro breakaway specialist since his debut in 2013. He's ridden every year since for Bardiani-CSF but is still without a stage win. The 25-year-old's only pro victory came last year in the Post Danmark Rundt.
Like Busato, Alessandro Malaguti is also riding his first Giro d'Italia - although he's been much more active. He tried to get into the break in stage 4 - riding solo for a number of hours - before throwing in the towel and dropping back to the peloton. A day later, the 27-year-old Nippo-Vini Fantini rouleur managed to make the break. That said, he has yet to finish higher than 141st in this Giro. He does have a pro win, though, to his name: the 2013 Route Adelie de Vitre (no, me neither).
The gap has come down to about 3:30 as the riders tackle a series of rolling roads through some forested hills. We'll soon return to the coast for the flat ride to Rimini, before the race goes back inland towards Cesana and then the finish in Forli.
This is Matteo Busato's first Grand Tour and he hasn't finished above 86th yet. He too has no pro wins to his name. The Southeast rider is from Veneto, so not too far from here. We'll get closer to his region later in the week.
This is Alan Maragoni's fifth Giro d'Italia but he's never finished a stage higher than 22nd position. This year, he's year to finish in double figures - his best effort being 100th in stage four. The 30-year-old has no professional wins to his name but enters his home region this afternoon when the peloton edges into Emilia-Romagna. He's from Lugo, just 20km away from the finish today at Forli.
It was Kevin Reza's birthday yesterday - the Frenchman turned 27. He's been absent from the sprints so far for FDJ even if he does have a decent kick. As Bryan Coquard's lead-out man in Europcar, he notched quite a few top fives and tens.
The peloton pass over the summit at 4:07 with Australian national champion Heinrich Haussler rooted to the back.
Malaguti leads the break over the summit of the Cat.4 Monte di Bartolo ahead of Marangoni and Buseto. They still have about four minutes over the peloton, which is being controlled by the IAM team of Matteo Pelucchi, as well as a few individual Lotto Soudal, Trek and Giant Alpecin riders.
So, who are the five leaders again? Oscar Gatto (Androni-Giocattoli), Nicola Boem (Bardiani-CSF), Alessandro Malaguti (Nippo-Vini Fantini), Matteo Busato (Southeast) and Alan Marangoni (Cannondale-Garmin). They've been out on this suicide mission since the 5km point and are now on the only climb of the day.
A reminder that Elia Viviani still wears the red points jersey with 78 points to Andre Greipel's 75. Marco Bandiera, who leads the Fuga classification for the most amount of kilometres out ahead of the race, is third on 60 points.
This morning, Australia's Michael Matthews effectively ruled himself out for the sprint: "For me today I won't be sprinting, I'll just be saving my legs for tomorrow and other opportunities which will be better for me," the 24-year-old told Eurosport. Is it bluff or is it to be expected, given that Matthews is not a pure sprinter in the same league as a Greipel or a Viviani? Time will tell.
The five leaders pass through the feed zone at Fano with a lead of 4:30 over the pack. The road is separated from the beach only by the dual tracks of a railway line.
Puncture for Aru, who needs a quick front wheel change. No fuss or bother on this sunny day on the east coast of Italy. Not a cloud in the sky - much like the Astana jerseys.
The five leaders hold a gap of four minutes after the first 80km of riding, which included just one slight rise but was otherwise pancake flat. The pack is keeping them on a tight leash - probably because of the two intermediate TV sprints which come before the finish with 40km and 22km remaining.
If and when we do see that bunch sprint, who can win? Andre Greipel, the German national champion, is the stand-out favourite after his win last week for Lotto-Soudal. Elia Viviani (Team Sky) also has a win to his name and the red jersey on his shoulders, so he'll be one to watch - as will fellow Italians Sacha Modolo (Lampre-Merida), Matteo Pelucchi (IAM Cycling) and Giacomo Nizzolo (Trek). Dutchman Moreno Hofland (LottoNL-Jumbo) is in form, which is more than can be said for Slovenia's Luka Mezgec (Giant Alpecin). Throw in Juan Jose Lobato (Movistar), veteran Italian Alessandro Petacchi (Southeast) and Australian fighter Michael Matthews (Orica-GreenEdge) and you have quite a roster of fast men waiting to make their mark.
Today's finish is flat but it does have a few technical moments: after a long, straight, flat run into Forli, thre's a right-hand bend before the 1km point and then a bottleneck ahead of a left-hand bend. We then have a straight of half a kilometre ahead of the finish - which is all but certain to be a bunch sprint. There's also a segment of flag stones which could spice things up.
Of these five escapees, Malaguti, Marangoni and Boem have all been on the offensive so far in this year's Giro. All Italian wildcard teams are involved in this break as they seek an elusive win. Cannondale-Garmin, the fifth team represented here, already have a win through Davide Formolo in stage four.
In other news, Fabio Aru's lawyer confirmed that the Italian is taking legal action against Greg Henderson after the New Zealand veteran accused Aru on Twitter of having a problem with his biological passport. The path is being taken "to protect the good name and honour of Fabio Aru and the team (Astana) he rides for," according to his laywe, Giuseppe Napoleone.
Of course, Porte is staying in his own campervan instead of hotels in a 'marginal gains' experiment by Sky. "It’s great having my own RV, sleeping in the same bed and not having to do the hotel changes and pack your suitcase every day. I think that’s the great thing about this team, they’re making it as stress free as they can for me." Further evidence of that came with Porte and his team-mates getting a helicopter ride for the rest day transfer instead of joining the rest of the race on a plane. "Last night when I got on the helicopter, looked down and saw all the [team] buses loading up... That was probably the best moment this week," said an upbeat Porte.
Some rest day news now. Richie Porte - in his first Grand Tour as Sky's leader - feels he is in "a fantastic position" after the opening week of racing. "We’ve seen that Astana’s really taken the race up. That suits me to be honest, if they really want to make the race hard. I actually thought it would be Tinkoff-Saxo making it hard, but you know, our team has been able to sit back and manage our guys as best we can. To be honest, I haven’t had to attack yet. I think Aru and Landa (Astana) are doing all the attacking for us."
The lead for the five Italians quicky nosed above the two-minute barrier - this one is here to stick, at least for a while.
The first attack of the day came after just 5km of riding as Oscar Gatto (Androni-Giocattoli), Nicola Boem (Bardiani-CSF), Alessandro Malaguti (Nippo-Vini Fantini), Matteo Busato (Southeast) and Alan Marangoni (Cannondale-Garmin) edged ahead in an all-Italian affair.
A reminder of the top five: Alberto Contador (Tinkoff-Saxo) leads Fabio Aru (Astana) by just three seconds, with Richie Porte (Team Sky) in third place at 22 seconds. Astana duo Mikel Landa and Dario Cataldo are fourth and fifth, at 46 seconds and 1:16 respectively.
No withdrawals over the rest day and so there were 188 riders in the pack when it rolled out of Civitanova this morning.
During yesterday's rest day the remaining riders made the journey north to the province of Macerata in the region of the Marche, just south of Ancona. Their batteries recharged, the next six-day phase of the 98th edition of the Giro d'Italia gets going with this long, but routine flat stage that should ease the pack back into action. The only worry may be some strong crosswinds coming off the coast.
Hello and welcome to live coverage of stage 10 of the Giro d'Italia - a rounded 200km flat ride up the Adriatic coast from Civitanova Marche to Forli. There's just one small Cat.4 lump and so this one is nailed on to see the sprinters reconvene in a fast and furious mass finale.
