Up ahead Tom Dumoulin is close to the finish. Dan Martin of Etixx-QuickStep attacks Chris Froome now. Irishman Martin is 17 seconds behind Froome in GC. 

Adam Yates is also in touch. There is a right battle now between the yellow jersey contenders. 

Chris Froome looks over his shoulder and appears to say to Nairo Quintana, 'if you don't want to do the work then fine. I'm the race leader.'

The pair ease off and the other GC contenders catch up.

These fans invading the road are doing my head in. 

Chris Froome now leads the attack in pouring rain but Nairo Quintana is with him. The rest of the field are left for dead. 

Yellow jersey holder Chris Froome is starting to lose team-mates as the peloton things out. But Team Sky's Sergio Henao leads an attack to try and eliminate Movistar's Nairo Quintana. 

Henao is only 23 seconds behind Froome in the overall standings. 

Pierre Rolland (Cannondale) is sliding out the back of the peloton as they continue to push the pace. Leader Tom Dumoulin is on a slightly flatter section, the Dutch rider has a 42-second lead as he approaches a set of hairpin turns. 

The rain is torrential now as the leaders climb into the clouds. There are a worrying amount of fans trying to take pictures with selfie-sticks. 

Now is not the time! 

If you listen to Radio 5 live sports extra, you can hear the hail bouncing off the roof! 

Tom Dumoulin still way out in front. The rain has hit the peloton now as they appear to crank it up. Nairo Quintana is shoulder to shoulder with yellow jersey holder Chris Froome.

The rain is really starting to bounce down at the finish. 

Tom Dumoulin (Team Giant-Alpecin) is still out in front and those in pursuit are running out of road. The Dutchman has a 45-second advantage.

It's a busy climb with lots of people. 

The weather today is baking hot, although it is starting to cool.

If the riders can get off the descent without any rain, then they probably won't be bothered by it because it'll help cool them down.

George Bennett (LottoNL–Jumbo) has just collided with a fan on the side of the road as the leaders make a small descent. The road looks slippy with a film of rain but what was that punter doing? They just walked out into the street without looking.

Against the best advice of my colleagues I hired out a bike earlier to have a go at this final climb earlier - It was awful!

It is a constant gradient going up and down...

And I'm pretty sure I saw the man Chris Froome had a brush with yesterday up towards the finish.

Hmm, let's hope he isn't lurking up there. There have been a few close calls already today.

Tom Dumoulin (Team Giant-Alpecin) fancies a bit of a push up the track and has a 21-second lead now. 

The peloton is eight minutes back, so it's safe to assume that the stage winner is likely to come from one of the leading group on the road. 

Cofidis' Dani Navarro is the latest to attack from the leading pack as they start their ascent up the first mountain-top finish. Movistar's Jesus Herrada is up there too, as is George Bennett (LottoNL–Jumbo). 

This from Rob earlier, and now he says it is raining at the finish. What part will that play?

The 10 leaders are down the other side of the Col de Beixalis and there are plenty of attacks coming from within as Rui Costa (Lampre-Merida) is the latest to the front.
