Other supermarket car parks are available on the ascent to Mount Ventoux - you just need to travel a bit to find them.

There's actually a stealth breakaway on today's stage.

Jonny and Ben from Leicester Forest Cycling Club are a long way in front of the professionals and attempting to cycle up Mount Ventoux today.

They'll go as far as the weather will allow them - and they're going to keep us up to date with their progress.

The peloton looks very happy to let the breakaway keep on marching ahead - they will believe the leaders will just fall completely off the pace when the legs have to grind up Mount Ventoux.

The gap is now at 18mins 33secs - the 13 men in the breakaway are Navarro, Clement, Pauwels, Chavanel, De Gendt, Sorensen, Coquard, Teklehaimanot, Lindeman, Keisse, Greipel, Lemoine and Vanmarckke.

When have you been beaten by the weather on your bike?

james condylis: Got caught in some epic rain on the Galibier in this year's Marmotte- freezing and terrifying descent!

Richard Cousins: Have cycled up Ventoux in 100kph winds so support the stage shortening, blew me clean across the road about 1k from the top.

A Few Good People: Mist blowing up hill at climb near Tabayesco in Lanzarote last Sunday. Stopped by low wall as bus trundled down hill.

Everyone has been talking so much about the wind, they forgot about the lions...

The leaders on this stage have just come through a relative pimple of a mound at Bouillarges - 46m high.

The breakaway, with 13 riders, is now 17 minutes ahead of the peloton. Big gap that, not too big, though. The French pair of Coquard and Chavanel are still in that lead group.

So, what's it like to go up this beast of a climb?

If you don't fancy finding out for yourself, don't worry, OJ Borg has done it for you. He joined cycling journalist Jeremy Whittle to ride Mont Ventoux and discuss the key moments on the ascent.

It's also worth noting there's a chase group of five riders sandwiched between the peloton and the breakaway - the meat in this cycling baguette, if you will.

Georg Preidler, Diego Rosa, Tom Jelte Slagter, Paul Voss and Alexus Gougeard are in that group - 5mins behind the leaders.

Still 13 men in the breakaway, which has now extended its advantage over the peloton to more than 15 minutes.

That will not be a concern to anyone, with all the climbing - and inevitable dropping of flies - still to come.

A reminder that all the yellow jersey contenders are together in the peloton.

Here's the lay of the land on today's stage 13.

As you can tell, it's pretty flat to begin with through the the vineyards and there's points for the sprinters to snaffle at 102.5km.

The riders will be coming up to Bouillargues shortly at the 55km mark.

Then there's two warm-up climbs - Cote de Gordes and Col des Trois Termes - before we get properly stuck in and start the ascent up Mont Ventoux.

You can disregard the final 6km - because of the high winds the stage will end at Chalet Reynard.

The wind has won a minor battle today. The gusts are so strong up Mount Ventoux that today's stage has been shortened.

What ridiculous weather have you faced on your bike and when have the elements beaten you?

Peter Sagan was the man to cross the line first in Montpellier yesterday, further tigthening his grip on the green jersey in the process.

The Slovak made a late, surprise break alongside Chris Froome, who looks utterly indefatigable.

Froome finished second, six seconds clear of the peloton, and with some cheeky bonus time he's 28 seconds clear in the yellow jersey, ahead of fellow Briton Adam Yates.

Four-time Tour individual stage winner David Millar can confirm it is windy on Mount Ventoux...

Sylvain Chavanel and Bryan Coquard are among the 13 breakaway riders - a couple of French riders getting some camera time on Bastille Day.

So, we're very much in the veg section of this stage before we get the meat at the end.

We'll have a detailed look at the stage shortly, but let me get you bang up to date.

They officially started at 11:22 BST, and it's been pretty flat as the peloton heads through the vineyards.

There's a breakaway of 13 riders, none of which are yellow jersey threatens, with the peloton about nine minutes up the road.

There's talk of gusts of 120km/h – 80/90mph - at the op of the mountain. It would not be safe up there to broadcast or for the riders. There were two members of the public hospitalised last night with hyhypothermia after spending the night in a tent.

OK, so it might not be as super grueling as initially billed.

There will be a tint asterisk next to the result of this stage when you're flicking through your almanacs in a few years' time.

If you haven't heard yet, today's stage 12 from Montpellier to the summit of Mount Ventoux will now finish 6km short at Chalet Reynard because of concerns over high winds.

Winds of 120km/h are expected.

It's a change that will suit some and scupper others.
