Hello and welcome to live coverage of stage 15 of the Tour de France - a rolling 183km ride from Mende to Valence that could well end in a mass bunch sprint if certain teams control matters and bring it back before the end.

Boasson Hagen took fifth ahead of Navardauskas, with Matthews also in the top ten. That was a great sprint - very competitive.

That's a hat-trick for Andre Greipel, who wins it by half a bike length ahead of John Degenkolb, Alexander Kristoff and Peter Sagan...

Degenkolb draws level but then fades... and it's a third victory for Greipel!

Greipel opens it up...

There's a counter from a Bora-Argon 18 rider as Stybar is caught ahead of the kite. Now Katusha come to the front for Kristoff - Greipel, Sagan and Degenkolb are all there too...

And it looks like Stybar will be caught before the flamme rouge... a ballsy effort, but in vain.

He has about 100m over the pack and is completely burying himself... but the chase has yet to get organised so Stybar may not hold on.

No response from the peloton! This is extraordinary... the standoff could result in a second win for Stybar...

There's a little rise as Daniel Oss has a pop for BMC. Zdenek Stybar uses this as a launchpad for his own attack - and he's opened up a small gap for Etixx.

BMC and Lotto Soudal going shoulder to shoulder as Giant and Cofidis come forward. The yellow jersey is near the front too, with two Sky team-mates.

They cross the river on a narrow bridge and will take a tight turn at the end - and it's the world champion Kwiatkowski who leads the pack.

The peloton has really strung out after two roundabouts in quick succession. Lotto Soudal haveformed their train and are near the front - but Katusha and Giant-Alpecin are quite far back for now.

BMC have come right to the front ahead of a tight left-hander on a roundabout.

It's train mode for the teams of the GC boys and sprinters now as they zip under the 10-to-go banner.

Orica-GreenEdge have come near the front for their man Michael Matthews. Lampre-Merida are there too, for their man, um, er, let me check... Davide Cimolai?

Another sprinter who won't win today is FDJ's Arnaud Demare, who's back in that Cavendish gruppetto. Oh, and Tyler Farrar of MTN.

Katusha's Giampaolo Caruso leads the peloton ahead of Belgian's Thomas De Gendt of Lotto-Soudal - working for their sprinters Alexander Kristoff and Andre Greipel. Then we have the Europcar train. Today is the last chance of a bunch sprint ahead of Paris - and Mark Cavendish is in a gruppetto 12 minutes off the back.

The riders are hugging the bank of the Rhone right now - some gorgeous aerial shots from the helicopter. Still Europcar drive the pace as Trentin and Hesjedal are swallowed up.

Just 30 seconds now for our two leaders, Trentin and Hesjedal. The carrots are surely cooked for these game chaps.

Peter Sagan needs a bike change and will have to fight back on to the peloton. His directeur sportif takes issue with the cameraman filming the swap and throws a water bottle at him...
