0km - Wiggins stays in sixth place and Uran stays in second place. The results have been modified. Perhaps all that rain did something to the timing systems... Thanks for joining us and see you tomorrow for more Giro action. Results & Standings
0km - Those GC results have yet to be confirmed - race organisers say there may have been an issue with transponders and so Wiggins would not have dropped any time. To be confirmed.
0km - The provisional top ten shows Luca Paolini still in pink, with Henao up to second place and Uran dropping to fifth after the latter punctured 12km from the finish. Big news is that Bradley Wiggins is no longer in the top ten - so if that is confirmed, then the Sky leader must have lost contact with the pack for a second time in as many days.
0km - Angel Vicioso (Katusha) was second and Paul Maertens (Blanco) third. Sergio Henao (Sky) took fourth.
0km - John Degenkolb takes the win! The German youngster passes Canola in the last 100 metres to take a superb win.
0.2km - It's John Degenkolb who is the rider chasing Canola...
0.5km - It's Marco Canola who has a great chance now as he leads with half a click to go - but a lone rider from Argos looks to be closing in.
1km - CRASH: The second rider in the pack - from Argos - goes down, leaving one Bardiani rider out ahead!
2km - The roads still not completely dry so this could be dicey.
3km - The Frenchman is caught and passed just after the 3km-to-go banner. The pack here is pretty large so we can expect a decent bunch sprint.
3.5km - Dupont is really giving it his all, but the BMC train are setting a strong pace in the chase.
4km - Pink jersey Luca Paolini is about 10 riders back. BMC have four on the front with a couple of Blancos.
4.5km - Dupont has a small gap but it's only a matter of seconds. Seven of them, perhaps.
5.5km - Another attack for Ag2R - it's Hubert Dupont.
6km - Cadel Evans, in the red jersey, looks very strong on the front with a couple of BMC team-mates. A dark horse today?
6.5km - Rabottini, a stage winner last year, is caught. Saxo lead the peloton. Perhaps Bennati is feeling good today? The Cavendish group is 45 seconds down.
7km - Rabottini won't stay out for long because Saxo Bank are leading the chase. But Vini Fantini have numrous riders poised - it's easy to spot them with their bright yellow shirts.
7.5km - It's a long, tough, slightly uphill drag to Matera - too much of an ask for Cavendish and Goss. Up front, Matteo Rabottini has made a move for Vini Fantini.
8km - Cavendish and Goss are both in a second peloton some way down - neither rider will win today.
8.5km - Vini and Bardiani counter attack. Numerous riders are making a move off the front as the three leaders are reeled in. Tom Danielson flats for Garmin and needs a wheel change. He is joined by Uran, who is still chasing back.
9km - The three leaders have just five seconds.
10km - Bardiani have now dropped the chase, with Androni setting the pace and Ag2R trying to disrupt. None of the serious sprinter outfits are getting involved as yet. Nacer Bouhanni is in this peloton towards the back, while Degenkolb is near the front. No sign of Cavendish at the moment.
11km - The trio are still out ahead as the grey clouds loom large. It's still sunny and so the rain should hold off.
12.5k - Attack by a Lotto Belisol rider who jumps the peloton in pursuit of the two leaders, who are fading fast. It's Lars Bak - and the Dane joins Vrecer and Gastauer. But they only have 10 seconds max on the pack - probably half that.
13.5k - Rigoberto Uran picks up a flat and needs to change a wheel with Sky team-mate Danny Pate. The Colombian is second on GC and so will hope to fight back on by the end. He'll join the Cavendish group in the chase.
14km - Bardiani driving the pace for the chase. They have Sacha Modolo for the win, plus yesterday's victor Enrico Battaglin.
14.5k - The two leaders - Vrecer and Gastauer - have 12 seconds on the pack. Cavendish yet to rejoin but he should be able to shortly because the pace isn't huge.
15km - Stefano Pirazzi is back with the main pack, but Ben Gastauer is pressing on with the help of Euskaltel's Robert Vrecer of Slovenia. The gap is not huge as Blanco lead the chase. Two riders from Bardiani are trying to bridge the gap now too.
16km - CRASH: Juan Jose Cobo of Movistar hits the deck on the downhill and needs a new wheel. His Giro just keeps getting worse.
18km - In 2003 when Robbie McEwen won in Matera, the Australian was 40 seconds down going over the same climb. So it's not out of the question for Cavendish today.
20km - Mark Cavendish is weaving all over the road as he's led over the summit by three team-mates 50 seconds down on Pirazzi. It's going to take a very big effort for him to get back on to the pack - but it's not impossible.
20.5k - Ben Gastauer of Ag2R-La Mondiale joins Pirazzi ahead of the pack - but it's the Italian who jumps out of the saddle to take maximum points and moves into second place on the blue jersey standings. Gastauer takes second before Visconti consolidates his lead with a point for third.
21km - Pablo Lastras sets an infernal pace for Movistar before popping and coming to a near stand-still. Meanwhile, Stefano Pirazzi attacks - he's in the hunt for those mountain points. He took a maximum three this morning. Cavendish is now on the rear end of the peloton, so it may be too big an ask.
21.5k - Some of the sprinters have already been tailed off - including Adam Blythe (BMC) Mattia Gavazzi (Androni Giocattoli) and Francesco Chicchi (Vini Fantini). OPQS's Gert Steegmans has been tailed off, which is not good for Mark Cavendish - although the Manxman is still holding in there. Stefano Garzelli, the oldest man in the race, is struggling.
22km - The rest of the break is swallowed up, with Mestre the last man to withstand the onslught of the pack. The road has recently been tarmac'ed and so it's a wonderfully smooth surface. But that won't make it any easier for sprinters like Cavendish...
23km - We're onto the Cat.4 Montescaglioso climb - 4km at 6.3% but with two kilometres at a solid 9% gradient. Andriato is the first of the leaders to be caught by the peloton.
24km - The hills loom on the horizon as the break makes a tight right-hander onto a long, straight road with just 45 seconds to play for.
25km - Eros Capecchi has put in a long stint on the front for Movistar. The 26-year-old Italian has been suffering with allergies this year so he'll welcome the wet weather. He even said he wouldn't ride the Giro again because of his condition. Anyway, he's put in a good shift for his man Fran Ventoso and now peels back off the front.
26km - The lead is down to 1:20 for the leading quintet. A reminder of the overall standings and stage results so far.
28km - Movistar, GreenEdge an Argos Shimano are all near the front. Miraculously it's now sunny in south Italy and all the riders have shed their rain jackets. BMC and Vini Fantini are towards the front too.
32km - No sign of Omega Pharma-Quick Step in the peloton. Word has it they are protecting their rider Mark Cavendish and will concentrate on getting him to the top of the Cat.4 climb. Should he be in touch then, then they will go all in for the sprinter.
35km - Garmin-Sharp have edged to the front - more to protect their man Ryder Hesjedal than any aspirations for the finish. The five leaders - Italian Alan Marangoni (Cannondale), Brazilian Rafael Andriato (Vini Fantini), Portuguese Ricardo Mestre (Euskaltel), Dutchman Brian Bulgac (Lotto Belisol) and Venezuelan Tomas Gil (Androni Giocattoli) - have just 2:30 over the pack now. The peloton has them right where they want them, that's for sure.
42km - I stand corrected: we have just seen some live images from the finish and it is now bathed in sunshine - although there is currently a huge clean up going on after thoat Matera monsoon. Just three minutes for the break now, so it's coming down fast.
45km - It's dry again for the leaders - these roads taking the riders in and out of pockets of rain. We haven't seen any images of the finish in Matera for a bit so we're unsure if the Apocalyptic conditions are still holding court - the lack of coverage and those grey clouds suggests that perhaps they are.
50km - This is the sixth time Matera has been used for a stage finish in the Giro d'Italia - but this will certainly be the wettest occasion. The lead of the five escapees is down to four minutes now.
55km - The five leaders are back under the deluge once again. They have five minutes over the peloton, which is being controlled by numerous teams - but not the Omega Pharma outfit of Mark Cavendish, the stage one winner. Cav is Sean Kelly's pick for the win today - despite those two climbs towards the finish.
60km - GreenEdge and Argos Shimano are driving the pace on the front of the pack, working in the interests of their men Matt Goss and John Degenkolb. The peloton has really strung out here - and the gap drops below the six-minute mark.
64km - The rain has eased up for a bit for the breakaway, who lead the peloton by 6:10. But back with the pack, it's raining cats and dogs.
68km - Bradley Wiggins and two Sky team-mates are making their way forwards from the back of the peloton. Now the pink jersey Luca Paolini drops to the back to speak to his Katusha team car. The gap is 6:45 for the break.
70km - At the second intermediate sprint, Rafael Andriato took the points once ahain ahead of Alan Marangoni, with Brian Bulgac in third. No change in the points standing a the top, with Paolini leading Evans and Cavendish: 35/30/28.
72km - The rain starts to fall on the peloton. They'll have to get used to this: apparently rain is on the cards for the next week...
78km - Many riders are now putting on their gilets and jackets in anticipation of the rain.
80km - The Argos Shimano team of John Degenkolb are near the front too. The German youngster won five stages on the Vuelta but has seen his chances limited in the Giro. In the only flat stage, we was held up by a crash - but won the bunch sprint for the peloton when it came home after the leading group.
85km - The lead is down to 6:30 for the five escapees as they head towards the cloudy horizon. Cannondale and Omega Pharma-Quick Step are setting the pace on the front of the peloton.
90km - Three of these leading five riders are experiencing their first taste of the Giro this year. sprinter Andriato, 2011 Tour of Portugal champion Mestre and time trial specialist Gil are all debutants. Bulgac broke his duck last year while Marangoni rode the Giro in both 2010 and 2011, making him the experienced man of the break.
95km - Live images show the riders powering along the coastal road on the Gulf of Tarento in sunshine - but up ahead, you can see those grey ominous clouds.
100km - Meanwhile, unkowing of the flooded streets that await them, the five leaders pass through the feed zone with a lead of seven minutes over the peloton.
105km - It's is raining like a monsoon at the finish in Matera: the finish straight has effectively become a river. This will be a logistical nightmare for organisers - all the electronics and wires and sockets have been completely submerged in the deluge. The race won't be able to come here if this continues!
110km - Result of the first intermediate sprint: 1. Andriato, 2. Marangoni, 3. Gil. But it has no bearing on the points standings - which is led by race leader Luca Paolini but has Evans wearing the red jersey by virtue of his second place in the competition.
115km - While it was sunny at the start, it's another miserable day at the finish: it's raining in Matera, the location of the famous 'Sassi di Matera' ancient town, built on the side of a ravine. Mel Gibson's 'The Passion of the Christ' was filmed in the maze-like Sassim, a UNESCO world heritage site. "Matera is the only place in the world where people can boast to be still living in the same houses of their ancestors of 9,000 years ago," says the Fodor's guide.
120km - For those complaining in the comment section below about the Eurosport TV coverage - you should check your facts before you rant off. The problem lies with Sky's listings. Eurosport is showing live coverage of stage five - and it's just kicked of on British Eurosport and Eurosport International.
125km - With Pirazzi out of this group, there is no threat remaining for the maglia rosa of Luca Paolini, meaning his Katusha team can take a back seat. The highest placed rider from the five leaders on GC is Cannondale's Marangoni, who is almost 26 minutes down. The gap is currently eight minutes for the escapees.
130km - Before entering the Eurosport commentary box, Sean Kelly just had this to say: "I expect Cavendish to win today. The two climbs are not too steep and he's had the last two days off. In fact, if Cavendish doesn't win then he should have two months of his wages docked."

135km - Before Stefano Pirazzi dropped back from the leading group he did pick up maximum points over the first climb of the day. Result: 1. Pirazzi (3pts), 2. Bulgac (2pts), 3. Marangoni (1pt).
140km - So, we now have just five men out in front in what is a fairly cosmopolitan break: Italian Alan Marangoni (Cannondale), Brazilian Rafael Andriato (Vini Fantini), Portuguese Ricardo Mestre (Euskaltel), Dutchman Brian Bulgac (Lotto Belisol) and Venezuelan Tomas Gil (Androni Giocattoli). The lead is around 6:45 over the Katusha-led peloton with the first intermediate sprint coming up in about 20km.
145km - Well, despite waxing lyrical about Stefano Pirazzi it seems that the Italian is no longer with the leaders. He could well have sunk back after a chat with the other leaders - at 3:06 in the overall standings, he was a threat to Luca Paolini's pink jersey. Like Emanuele Sella yesterday, he had to be jettisoned for the sake of the longevity of the break.
150km - The best known rider from this leading group is Stefano Pirazzi, the 26-year-old Italian from Bardiani Valvole. This is Pirazzi's fourth Giro d'Italia and the climber has often been involved in breakaways - although he's still yet to pick up a maiden win in his home tour. Last year he won the mountains jersey in Tirreno-Adriatico and this year he finished seventh in the Giro del Trentino.
155km - The average speed for the first hour of the race was 44.3 km/h which is pretty high. The leaders have passed over the Cat.4 Cipolletto climb but no news of who picked up the points as yet.
160km - Spain's Pablo Urtasun has retired from the race. The Euskaltel rider crashed heavily in stage one of the race and has been riding in some considerable pain ever since. Urtasan is the second rider to abandon the race following Sandy Casar's withdrawal ahead of stage three. So we have 205 riders remaining - from 23 different teams.
165km - The break did hold a nine-minute lead over the pack but it has crept down to eight minutes.
170km - Stefano Pirazzo has a puncture. There are two Cat.4 climbs today - perhaps the Italian is eying maximum points over both cols? Even that would not put him in the blue jersey - he's only has 5pts to Visconti's 13pts with a maximum of 6 available today. In short: it's odd that Pirazzi's in this group today, this not really being a stage suited to his strengths - unless this break stays out all the way.
175km - After Bradley Wiggins lost time yesterday and Rigoberto Uran cemented his 2nd place on GC with a strong finish in 4th, Sky were forced to deny that there was some form of "Colombian conspiracy" within the team. Both Uran and his compatriot Sergio Henao are said to be leaving at the end of the season following news that Richie Porte has extended his contract - with conspiracy theorists suggesting they will ride for themselves, and not Wiggins, in the Giro. Cycling - Porte extends deal with Team Sky
180km - The lead is around eight minutes for this six-man break, which includes riders from all three Italian wildcard teams.
185km - BREAK: Six riders are off the front of the peloton. They are Tomas Gil (Androni Giocattoli), Stefano Pirazzi (Bardiani Valvole), Alan Marangoni (Cannondale), Ricardo Mestre (Euskaltel), Brian Bulgac (Lotto Belisol) and Rafael Andriato (Vini Fantini).
190km - The white jersey competition for the best rider under 25 years of age is being led by Italy's Fabio Aru (Astana). He's 19 seconds faster on GC than Rafal Majka (Saxo Bank) and 26 seconds to the better of Carlos Betancur (Ag2R-La Mondiale).
195km - There's no news filtering through on race radio as yet but we'll keep you posted with the developments of the stage as soon as we get updated. In the mountains classification, Italy's Gio Visconti (Movistar) crossed both summits yesterday in third place to pick up enough points to move back into the blue jersey. He has 13 points, with Belgian Willem Wauters (Vacansoleil) and Colombian Robinson Chalapud (Colombia) tied on 9pts. The latter crossed yesterday's Cat.2 summit ahead of the peloton.
200km - Luca Paolini may be in pink but what of the other jerseys? The Italian actually leads the points classification but it's the Australian Cadel Evans, after two high finishes in succession, who is now in the red jersey. He is 5pts behind Paolini but 2 points ahead of Mark Cavendish. Yesterday's winner, Enrico Battaglin is another 3 points down in fourth.
203km - After yesterday's rain the riders are being treated to some more clement weather today with the sun out and the temperature in the early 20s. After a 7.7km neutral zone, the flag is waved and the stage gets under way...
11:30 - Today's stage is another long schlep with a very flat middle section - in this case, along the coast on the instep of the foot of Italy, the Gulf of Taranto. A break will no doubt form early on the road but be reeled in before the two small tests of the day: a Cat.4 climb 20km from the finish and then the last punchy uphill rise towards the finish. For the sprinters that can hold their own in the hills, this should be a chance to take a bit of glory.
11:25 - Italian Luca Paolini (Katusha) retained the pink jersey on Tuesday after his victory on Monday's stage three. He leads Rigoberto Uran of Team Sky by 17 seconds, with Benat Intxausti of Movistar in third at 26 seconds. Astana's Vincenzo Nibali is fourth at 31 seconds ahead of fifth place Ryder Hesjedal, the defending champion from Garmin-Sharp. Wiggins drops to sixth, tied for time on his Canadian rival - 34 seconds off the pace. Results & Standings
11:20 - Yesterday, Britain's Bradley Wiggins lost precious seconds to his main rivals in a sodden stage four of the Giro d'Italia, won by Italian youngster Enrico Battaglin. Race favourite Wiggins of Team Sky crossed the line in a second group 17 seconds behind the winner, Battaglin of Italian wildcard team Bardiani Valvole, to drop from second to sixth on GC. The 2012 Tour de France champion was held up after three riders hit the deck in Apocalyptic conditions towards the finish. Giro d'Italia - Victory for Battaglin as Wiggins loses time
11:15 - Welcome to live coverage of stage five of the Giro d'Italia - a largely flat 203km ride from Cosenza to Matera in the deep south of Italy which could well come down to a bunch sprint despite two punchy climbs towards the finish.
