It certainly looks like Greg is going to win today.
If he can continue like this he'll take the stage win and the yellow jersey.
Summary
Van Avermaet wins stage to take yellow jersey
Froome and GC contenders are 5mins 17secs behind
Contador and Nibali struggle
Stage five: 216km from Limoges to Le Lioran

Reign it inpublished at 15:53 British Summer Time 6 July 2016
7.6km to go
Operation damage limitation is being led by Team Sky and Movistar.
They only really need to worry about each other - and they both sit in the remnants of a peloton devastated by the climbs - but they will be a little bit worried by Van Avermaet's potentially whopping lead in the GC.
The gap is 5mins 43secs.

11.3km to go
It's Team Sky at the front of the peloton, driving it on. A few from Movistar are struggling with the pace - although Nairo Quintana is not one of them, he's still there.

Polka dot jerseypublished at 15:45 British Summer Time 6 July 2016
Greg van Avermaet is, of course, the first over the top of Col de Font de Cere and he collects maximum polka dot points. His lead over the peloton is still at six minutes.
Yellow jerseypublished at 15:41 British Summer Time 6 July 2016
15.5km to go
The peloton, with all the GC contenders - aside from Vincenzo Nibali, depending on how you saw his chances - is now six minutes off the leader.
How far behind Van Avermaet will Chris Froome be in the yellow jersey rankings?
Avermaet home and hosed?published at 15:39 British Summer Time 6 July 2016
16km to go
Greg van Avermaet is up and over Col du Perthus. It's all, relatively, easy now.
There's a small bump on this descent and then the category three climb to Col de Font de Cere.

Greg goes it alonepublished at 15:36 British Summer Time 6 July 2016
17km to go
Greg van Avermaet has decided he is not waiting for anyone.
He pumps the legs and leaves Thomas de Gendt on his tod and powers up towards the top of Col du Perthus.
It could be a stage-winning move - and one that could secure him the yellow jersey.

Former GB cyclistToday is one of the days where you wont win the Tour de France but if you have a bad one then you could rule yourself out of the chance of getting on the podium or getting a yellow jersey later on in the race and ultimately in to Paris.

18.6km to go
After scything down the other side of Pas de Peyrol, Greg van Avermaet and Thomas de Gendt are looking up at the ascent to Col du Perthus.
Another category two climb - 4.4km at 8%.
Ouch.

Image source, AFPA very English feel to this route today.
It looks a bit like Snake Pass, a road I am only too familiar with and is still the main link between those two northern metropolises of Manchester and Sheffield. Progress eh?
Saggy Saganpublished at 15:25 British Summer Time 6 July 2016
23 km to go
Oh Sagan looks like he's hurting. And to make matters worse he's held up by some photographers.
Hasn't lost his sense of humour though - he looks over to the motorcycle cameraman as if to say "come on, keep up".

24km to go
Plenty of riders are being laid to waste by this first category two ascent of the Tour and the increase in pace in the peloton.
Massif Central? Massif destruction!
None of them are Chris Froome or Nairo Quintana. Fabio Aru looks fine too.

Van Avermaet and De Gendt are free-wheeling on the first tasty descent of the day.
