0km - So that's three for Greipel now, who draws level with Sagan.
0km - Andre Greipel takes the win by half a bike length over Sagan!
0.2km - Boasson Hagen has Greipel and Sagan in his wheel as Wiggins peels off...
0.8km - Now it's yellow jersey Wiggins on the front leading out Boasson Hagen!
1km - Sanchez is caught by the Argos rider. Under the one to go banner.
1.5km - The Spaniard has opened up a gap - and Lotto are nowhere to be seen. In fact, it's just Sky on the front. Now an Argos rider takes off.
2km - ATTACK: Luis Leon Sanchez of Rabobank pings off the front.
2.5km - Vino and Albasini are caught! And the main pack is coming back together too as trhe pace slows slightly.
3km - Evans, Wiggins, Froome and Nibali in the Lotto group, but it's only about 20-strong.
3.5km - Green jersey Peter Sagan is hitching a lift with the Lotto train - four riders and then him. Very cheeky. And there's another split - a huge split!
4km - Vino is shaking his head - but his gap with Albasini is up to 14 seconds. But the pack is closing in...
5km - Lotto are poetry in motion on the front. But the leaders Vino and Alba still have 10 seconds.
6km - A very dangerous right-hand bend into a roundabout there. Lucky it's strung out - had the pack arrived in as a bunch, that would have been carnage.
7km - The leading duo have 11 seconds. It's a tall order.
8km - Goss and Cavendish are certainly out of it: their chasing group is now three minutes back.
9km - The pace is high and the main pack is really strung out. It's a downhill run-in today, with a tight bend a few hundred metres from the finish. Could prove to be very tricky - and Greipel may not have the recquisite acceleration out of that last bend.
10km - Vino and Albasini have 22 seconds on the main pack, which is being bossed by Lotto. No signs of the notorious crosswinds as yet...
13km - Andre Greipel doesn't appear to be in this main pack - no, hang on, he is there. And he has four team-mates. The German has to be the favourite today with that lead-out.
14km - Cavendish is riding in a group 1:30 off the back of the main group, which includes the yellow, green and white jerseys. Vino and Albasini have 10 seconds on the pack.
16km - ATTACK: Alexandre Vinokourov has a gap over the peloton. Nice work from Astana's talisman. GreenEdge Swiss maestro Michael Albasini is in pursuit.
18km - We have a leading group of about 30 riders with numerous chasing groups containing many sprinters trying to get back on.
20km - Sylvain Chavanel of OMQS on the front now, it seems. Now Egoi Martinez for Euskaltel. The green of Peter Sagan is there. And it's coming back together, with Sky beginning to take control.
21km - The race is really strung out now - it's going to be a hard one to predict, and there's still time for it to come back together.
22km - Over the top they go - Van den Broeck ahead of Evans and Wiggins. Then Nibali and Froome too. All the sprinters gone. But Boasson Hagen and Albasini are there. Now the fun time: the descent.
23km - Evans, van den Broeck and Roche are a few bike lengths ahead of Wiggins, but he has it in control. Back together again. Caruso is caught too. Nibali is there, and Froome. And Albasini for GreenEdge. Goss is one of the riders to be dropped, as has Gerrans.
23km - Morkov has been overtaken by Giampaolo Caruso of Katusha, who jumped out of the pack.
23km - Cavendish and Farrar are off the back. Morkov is really struggling now. He has 20 seconds. Wiggins and Evans are on the front of the pack, as is Froome.
24km - Morkov is swaying across the road from side to side - and almost rides into a group of spectators on the left. He's approaching the half-way point but only has 35 seconds.
24km - Morkov is onto the Cat.3 Mont Saint-Clair - 1.6 kilometre-long climb at 10.2%. The break are 45 seconds back and is about to be swallowed up by the streamlined peloton.
25km - Lone leader Michael Morkov now has one minute over the bunch, which is about to catch the other seven escapees.
26km - CRASH: Seven or so riders down, uncluding polka dot jersey Frederick Kessiakoff (Astana) and Brett Lancaster of GreenEdge.
27km - Sean Kelly is predicting "a group of 40 riders coming to the finish together at least". Morkov own't be one of them: his lead is down to 1:15.
30km - Morkov's face is a picture of pain. He only has 1:45 now. The peloton is arriving on the coast now, with three BMC men driving the pace. The seven other escapees are right in between the lone leader and the pack.
31km - That's a huge split in the peloton thanks to the effort of BMC - but Sky are keeping their main men Wiggins and Froome near the front.
33km - The splits are starting in the peloton: around 30 are off the back - and another 10, including Valverde and Leipheimer, further back. Riche Porte is there for Sky, and Burghardt for BMC.
35km - The effort is clearly getting to Morkov, whose lead drops to 2:35 on these well surfaced and wide roads ahead of the major test of the day, the Cat.3 Mont Saint-Clair.
38km - The average speed for the third hour was much quicker: 47kmh for the leaders.
40km - Jerome Pineau leads the seven-man chasing group. They let Morkov go about 20km ago and are now riding 1:10 down on the Dane.
42km - One rider who is expecting a surprise today is Rabobank's Bram Tankink, who tweeted this morning: "Everyone expects a mass sprint today, but it looks like the Mistral is going to bugger us. Expect a war."
44km - The pace is really quite frantic in the bunch as BMC move to the front. Perhaps a prelude to the fierce winds predicted. Morkov is now 3:30 ahead.
48km - Morkov is actually increasing his lead over the pack with this brave ride. 3:05 now.
50km - Morkov is really giving it his all out there. This is his fifth break of the Tour and he's still in search of that elusive win - as are his team, Saxo Bank-Tinkoff. He has 45 seconds on the break and 2:55 over the peloton. No betting man would put any money on him staying out, but miracles sometimes happen.
55km - Orica-GreenEdge still on the front of the peloton as the pace is raised considerably. They trail Morkov by 2:40 with that Cat.3 Climb about 30km away.
60km - Green jersey Peter Sagan is off the back of the peloton after needing a new wheel following a puncture. Meanwhile, Morkov continues on his way. He's 2:30 clear of the peloton and 30 clear of the other seven escapees.
63km - ATTACK: Michael Morkov decides it's time to pull clear of the leaders. The peloton is just two minutes back so the Dane feels that the best thing would be to time trial on his own off the front. To be fair, the break is totally disorganised. Morkov is also riding in memory of his father, who passed away five years ago to the day.
64km - Jerome Pineau is riding right in the stream of his Quick Step team car after picking up a puncture. He had a wheel change and now he's back with the leaders. He seems to put his hands up at the TV camera, as if apologising to the commissaires for that illegal manoeuvre. On Bastille Day, you'd think the French race directors will cast a bling eye...
66km - Kern is back with the bunch now. He got very cross with the French TV moto camera for following his ride back to the peloton. The gap of the eight-man group is 2:15.
70km - Europcar's Christophe Kern has been dropped off the back on that last little climb. The Frenchman finishes in last place yesterday, more than 16 minutes down. He's clearly struggling from the effort he made in setting up that win for Rolland in the Alps.
76km - Interestingly, the only French team not to have a French man in the break is Europcar. Jean-Rene Bernaudeau's men have been in virtually every break so far in this year's race, plus have two stage winners in Voeckler and Rolland. They're obviously not feeling very patriotic on Bastille Day - either that, or they fancy Yohann Gene for the sprint.
80km - The lead continues to tumble. It's 3:22 for the eight escapees as Peter Velits receives some medical attention on his left knee following that tumble.
84km - GreenEdge still setting the pace on the front of the peloton ahead of the Sky team of yellow jersey Bradley Wiggins. Old boy Chris Horner of RadioShack appears to have had a mechanical because he's riding back through the cars onto the back of the bunch.
87km - CRASH: Peter Velits of Omega Pharma-Quick Step clips the barrier ahead of the intermediate sprint and hits the deck. He' back on his bike and rather gingerly continues on his way. He has Dries Devenyns to help pace him back.
88km - GreenEdge decide to contest the intermediate sprint after all - but then they have a rethink once they see Peter Sagan power clear. The Slovak takes points for ninth place ahead of Andre Greipel.
90km - Pablo Urtasun sportingly asks his fellow escapees if they mind if he rides over the intermediate sprint in pole position. No one seems to care, so the Euskaltel man pockets 2,000 euros and they continue on their way.
92km - The peloton is on to an uncategorised climb ahead of the sprint - the road snakes up the side of the slope and is very pretty from above. It has to be said, the images from this year's Tour have been quite astounding. The organisers have certainly put on a route touristique par excellence.
93km - The leaders are 3km away from the intermediate sprint, with Tommy Dumoulin desperate to pick up some water from his Cofidis car. The pocket rocket Frenchman is the quickest sprinter of the eight riders, so he'd be the man to watch should this break go the distance.
96km - If Dutchman Roy Curvers wins today, he'll be the 7th oldest Tour de France debutant to take a stage. The Argos Shimano man is 32 years and 200 days. The record is held by Walter Diggelmann, who won a stage in 1852 aged 36 and 327 days.
102km - Very narrow roads for the leading eight now - and the surface is pretty uneven and coarse. Expect some puntures in the bunch in a bit. The gap has dipped below the five-minute mark.
105km - We asked who you thought would win today. 'Harry' thinks the break will stay out and picks Pineau. 'Duncan' "can't see it being anything but a bunch sprint" and tips Cavendish to pip Goss and Sagan. 'William' has gone for Cav, 'Andy' thinks Sagan will make it four, and 'seabass' has predicted Greipel to draw level with Sagan's three wins.
110km - Sebastian Langeveld, Brett Lancaster and Peter Weening are the GreenEdgers doing the work for Gossy on the front of the peloton. The gap is fairly stable at 5:20.
114km - The eight leaders are 5:20 ahead. A reminder of their names: Pablo Urtasun (EUS), Samuel Dumoulin (COF), Matthieu Ladagnous (FDJ), Michael Morkov (STP), Roy Curvers (ARG), Jimmy Engoulvent (SAU), Maxime Bouet (ALM) and Jerome Pineau (Omega Pharma-Quick Step).
116km - The leaders have gone through the feeding zone. Bjarne Riis also thinks today could be very important for the GC: "Today could be one of the most dangerous days for the GC. It's a tricky finale and if the wind is correct, it's going to be a spectacle."
118km - Saxo Bank's Bjarne Riis to Eurosport this morning: "Wiggins is controlling with a strong team, but it's still open - especially for Nibali and of course Cadel, we haven't seen the last of him yet. To be honest, I don't know how much of a rivalry there is between Wiggins and Froome. From outside there's probably a problem, but not for them. For us it's been a different Tour. We miss Alberto a lot. We don't have a win yet but we keep fighting."
120km - Team Sky would like to see world champion Mark Cavendish take a second win today. "We'd like to win. We want to keep Chris and Brad out of trouble but that goes hand in hand with trying to set Mark up for the sprint," said Dave Brailsford this morning.
125km - Average speed for the second hour of racing was 42.5kmh. Who is your tip for the win today? If you're an internet reader, have your say in the comment box below...
130km - Reports coming in from the finish are saying that the crosswinds are considerable. A Reuters reporter on Twitter is saying "expect chaos in last 30km" while Daniel Freibe, the author of a recent biography on Eddy Merckx, says "expect drama".
132km - The lead is down to 4:30 now as Orica-GreenEdge continue their pace-setting on the front of the peloton. Matt Goss is still without a win, but he'll face steep competition from the likes of Andre Greipel, Mark Cavendish and Peter Sagan tonight. In fact, with that climb and the technical finish, perhaps the favourite today is that man Sagan...
136km - As mentioned earlier, this is the fifth break of the Tour for Saxo Bank-Tinkoff's Michael Morkov. Before today's stage, he had notched up 622km out ahead - more than any other rider on the Tour. It should earn him a new improved contract at Bjarne Riis's team. Today his reason for breaking? "It's been exactly 5 years since my father passed away. I want to win this stage to honour him."
140km - The last French rider that won on Bastille Day was David Moncoutie in 2005. The veteran Frenchman won't be able to do repeat his feat: the Cofidis rider had to abandon yesterday after a nasty fall in the decent of the Grand Cucheron, the first climb of the day, after attacking in pursuit of the leading group.
145km - Orica-GreenEdge have reduced the gap of the Bouet group to 5:40. It peaked at 9:20 earlier in the stage.
150km - Today's stage looks straight-forward but the finale could prove troublesome: the Cat.3 Mont Saint-Clair would make a selection with its 10.2% average gradient, and then there's the small matter of the notorious crosswinds on the Mediterranean Coast. Fair to say, Team Sky will be very anxious during the last hour of racing - they will want to keep their man out on the front of the peloton to avoid any splits or echelons.
155km - CRASH: Yukiya Arashiro (Europcar) and Aliaksandr Kuchynski (Katusha) have crashed. But it doesn't look too bad.
160km - For Jimmy Engoulvent, Roy Curvers, Samual Dumoulin and Jerome Pineau, this is the first time they have been incolved in a break in this Tour. This is Maxim Bouet's third break of the race, the Frenchman was on the offensive in stage 1 and stage 12 yesterday. Joining Bouet in stage 1 was Michael Morkov. The Dane also attacked in stages 2, 3 and 10. Matthieu Ladaganous was involved in breaks in stages 5 and 10. Pablo Urtasan was in the break in stages 1 and 5.
162km - The lead has dropped to 7:15 for the escapees. The final jersey standing to catch up on is the white jersey for best young rider. It's a two-horse race with 23-year-old American Tejay van Garderen (BMC) leading 22-year-old Frenchman Thibaut Pinot (FDJ) by 1:54. White jersey standings
165km - Tony Gallopin of RadioShack has abandoned the race. The young Frenchman has been ill for the past few days.
170km - The average speed for the first hour of racing was 41.8 kmh for the leaders. There is only one former Tour stage winner in this group - Samuel Dumoulin.
175km - The lead of the eight escapees balloons to 9:20 as the peloton is happy to take it easy in the opening part of this Bastille Day stage.
180km - Movkov was an early leader of the polka dot jersey standings if you look back to the first week. Now the man in red spots is the Swede Frederik Kessiakoff of Astana, who leads Pierre Rolland (Europcar) by 11 points. There's one categorised climb today - the Cat.3 Mont Saint-Clair that comes 23km from the finish. Polka dot jersey standings
182km - The lead is up to 6:20 for the escapees. Michael Morkov has been in four breaks prior to this one. It's the fifth anniversary of the death of the Dane's father and Morkov said before the stage that he would attack in a bid to pick up a win to honour his father. As we have learnt already from this Tour - when Morkov says he's going to attack, he attacks.
185km - Orica-GreenEdge lead the peloton: the Australian team want a win at all costs for their man Matt Goss today. Goss spoke to the Tour's official site about his points docking yesterday: "It was a bit over the top but I have to deal with it and move on. There was loads of room on the road. Sagan came towards me with his head down, my head was down also. The punishment really didn't fit the crime. I'm not sure if the green jersey is a target for me now, to be honest."
188km - Following stage wins for Team Sky’s British trio Mark Cavendish, Chris Froome and Bradley Wiggins, another member of Team GB’s Olympic selection got in on the act as David Millar prevailed on the Tour’s longest stage yesterday. It gave inspiration for our resident blogger Blazin' Saddles to write a provocative piece reminding Australia - Team GB's big Olympic rivals - that they have no wins from their 12 riders in the Tour so far. Blazin' Saddles blog: Australians eclipsed by great Britons
190km - Pineau has caught the leaders so we now have an eight-man group - five of whom are French - with a lead of four minutes over the peloton. A predictable scenario for Bastille day.
195km - This group is no threat to the GC with Maxime Bouet the best-placed rider, more than an hour down on Bradley Wiggins. Pineau still chases the seven leaders, who have come onto the first rise in what is actually quite a lumpy parcours today towards the coast.
200km - We now have seven leaders on the road, with one rider - Jerome Pineau (Omega Pharma-Quick Step) in pursuit. The Frenchman is one minute down on the break, which leads the peloton by almost three minutes.
205km - Today could well be a significant day in the battle for the green jersey - although the decision to penalise Matt Goss yesterday has certainly made things easier for current points leader Peter Sagan. The Australian pipped Sagan in the sprint for sixth place at Annonay, but was judged to have swerved in front of the Slovakian tyro and was docked 30 points accordingly. Sagan now has 252 points with Goss far behind on 198. http://uk.eurosport.yahoo.com/cycling/tour-de-france/standings/green.html
210km - The five leaders now have two minutes over the peloton and 30 seconds over the duo in pursuit. This is a fast start to the stage.
212km - The five leaders are Pablo Urtasun (EUS), Samuel Dumoulin (COF), Matthieu Ladagnous (FDJ), Michael Morkov (STP) and Roy Curvers (ARG). They have two Frenchmen in pursuit: Jimmy Engoulvent (SAU) and Maxime Bouet (ALM). The peloton is about one minute in arrears.
215km - Burghardt is being pursued by four other riders. They manage to catch him and the five ride with 15 seconds over the peloton. It's a sunny day in south France, with temperatures in the mid-20s.
216km - Straight away we have an attack from BMC's Marcus Burghardt. That's four in four days from the big German.
217km - No overnight withdrawals to report as the remaining 164 riders complete the neutral zone and get this stage under way. The crowds at Saint-Paul-Trois-Chateaux are out in their masses on Bastille Day - they'll be hoping for another French win today...
10:55 - Bradley Wiggins retained his 2:05 lead in the general classification over Sky team-mate and compatriot Chris Froome, while Italian Vincenzo Nibali still in third, 2:23 down on the yellow jersey. Yellow jersey standings
10:50 - Yesterday, David Millar won a fourth stage for Great Britain in the Tour de France after outsprinting Jean-Christophe Peraud in Annonay-Davezieux. It was also a career fourth individual stage win on the Tour for the veteran Scottish rider, nine years after his previous win on the world’s biggest bike race. Millar used all his experience to outfox his rivals in a five-man breakaway as fellow Briton Bradley Wiggins (Team Sky) retained his leader’s yellow jersey. Report: Millar magic on stage 12 of Tour
10:45 - Welcome to live coverage of stage 13 of the Tour de France - a 217km trek from Saint-Paul-Trois-Chateaux to Le Cap d'Agde on the Mediterranean coast on Bastille Day.
