Classification

With 5km to go, yellow jersey leader Vincenzo Nibali puts the hammer down and ups the pace. Within a couple of minutes, he slashes the gap to the leader from two minutes to one minute 39 seconds.

Lots of attacks on the mountain right now as Rafal Majka goes it along, after being dragged along by team-mate Nicolas Roche. He wants to hold on to the polka dot jersey.

Meanwhile, there's been an attack from Thibaut Pinot, who lies third overall, in the yellow jersey group and race leader Vincenzo Nibali.

However, Alejandro Valverde, who lies second in the general classification, can't respond and gets dropped.

Giovanni Visconti goes it alone, while Nicolas Roche drops back into a group which features polka dot jersey holder Rafal Majka, who himself has dropped rival Joaquim Rodriguez.

"Vincenzo Nibali isn't really under any pressure, he's got a team-mate with him as a safety net just in case he has any technical problems."

Nicolas Roche (pictured) and Giovanni Visconti have gone clear, shaking off the challenge of Amael Moinard and Pierre Rolland. The chasing group, which features Joaquim Rodriguez, is 37 seconds further back.

We're approaching the bottom of the final climb - the Saint-Lary - Pla d'Adet, which has gradients of 10% in the opening few kilometres. Expect the field to spread out as riders attack.

Frenchman Romain Bardet has attacked on the descent, with the six-man yellow jersey group, which has broken free of the peloton, 23 seconds behind.

A 14-man lead group has a one minute and 53 second lead.

Joaquim Rodriguez injects a burst of speed to go clear of the field and take the maximum King of the Mountain points to further extend his lead at the top of the standings. It looks like he'll be wearing the polka dot jersey tomorrow.

Good effort from Vasil Kiryienka but his time at top is over. The group, led by Nicolas Roche, gobbles him up just before the summit. Kiryienka can only watch on as all 13 riders pass him.

"I think Kiriyienka is starting to struggle now, and the lead he has now will not be good enough as he hits the penultimate climb. It is a bit of a worrying moment when the cars come in around you because it tells you that the chasing riders are getting closer to you."

Nicolas Roche has moved to the front of the chasing group and is dragging it along. The result is that the gap to leader Vasil Kiryienka is down to 43 seconds and closing.

"I don't think the gap is enough for Vasil Kiriyienka. Unfortunately for him the tough climb coming up and then the one to the finish will be too much for him."

Vasil Kiryienka is grimacing as he pushes on up the Col de Val Louron-Azet. Is his time alone at the front coming to an end? He still retains a lead of one minute over the chasing group and three minutes 14 over the peloton. Just over 26km remain.

Sprinters green jersey holder Peter Sagan has dropped out of the peloton and is in the gruppetto, which has the sole aim of surviving the mountains to get to the finish within the time limit.

As the riders continue their progress up the Col de Val Louron-Azet, the third climb of the day, Vasil Kiryienka sees his lead cut down to one minute.

The chasing group has reduced to 16, with the peloton three minutes and 30 seconds further back.

Back in the day, riders used metal bidons (water bottles) and stopped at village fountains to refill them. Nowadays, they've got someone to do it for them.

Called a soigneur, it's their job to fill up those hundreds of bottles a day and pack the musettes. He or she will also makes sure that the riders sleep, eat and drink well and also gives the riders their daily massages.

Vasil Kiryienka has form in breakaways. The Team Sky rider bolted away from the pack in stage 18 of last year's Vuelta a Espana at the uphill finish of Pena Cabarga, riding the last 40km solo.

He also has two stage wins on the Giro d'Italia. Can he complete the set today with a maiden stage win in the Tour?

Vasil Kiryienka's lead is down to one minute and 20 seconds over a group of 17 - now including Nicolas Roche and Jesus Herrada Lopez, who had previously made a break for it to get the points at the summit before dropping back.
