Welcome to live coverage of stage 11 of the Tour de France - a short but beastly 148km ride from Albertville to La Toussuire that features four climbs including the fearsome Madeleine and Croix de Fer climbs, and the summit finish at La Toussuire.

The leaders are onto the Cat.2 Col du Mollard - (1 638 m) 5.7 kilometre-long climb at 6.8%. It blows apart straight away. Horner seems to suffer a mechanical and then riders drop like flies as Rolland and Kiserlovski ride off the front.

The leading group: Horner (RadioShack), Rolland (Europcar), D.Martin (Garmin), Ten Dam (Rabobank), Kiryienka (Movistar), C. Sorensen (Saxo Bank), Kessiakoff, Kiserlovski (Aatana) and Velits (Omega Pharma-Quick Step).

That's a good descent by Frank Schleck: the RadioShack rider is back with the yellow jersey group. The leading Rolland break are 2:15 ahead now.

Mick Rogers missed a corner there but thankfully had a run-off and so did not come a cropper. The Australian has been enjoyed something of a renaissance in this year's Tour - he's having a wonderful race.

Sky on the front of the yellow jersey group for this fast descent. We still have two more climbs today. The leaders still have 2:10.

Confirmation of the top three over the Croix de Fer: 1. Kessiakoff (25), 2. Rolland (20), 3. Sorensen (16). The Swede cements his lead in the polka dot jersey standings.

Porte was just dropping back to get water bottles - that's how much Sky are in control. Nibali also goes back to his team car for water, plus a mechanical. The yellow jersey group cross the summit 2:10 down on the leaders.

Pierre Rolland launches the sprint for the mountain points, but it looks like Frederik Kessiakoff just pipped him for the 25 points.

Sky in total control, with Rogers leading Wiggins and Froome. Porte has dropped back.

The five leaders are now onto the Croix de Fer final rise to the top. Evans and Van Garderen have been on the back of the yellow jersey group since being caught. Did they go too early or are they just preserving their energy for the final climb to La Toussuire?

The five leaders are crawling through the masses as they approach the summit of the climb. Chris Horner leads them over the top of the Glandon. They now have a little descent and then the Croix de Fer.

The yellow jersey group does not include Menchov. Here it is: Wiggins, Evans, Froome, Nibali, Van Garderen, Brajkovic, Pinot, Basso, Porte and Rogers. Both Vino and Valverde were there, but have now been distanced.

Evans and Van Garderen are back with the yellow jersey group. Evans is struggling on the back. Sky, meanwhile, are dominating: still four riders there in this 10-man group.

Horner and Rolland now on the front. They are with three other riders on the front of the race.: Kiserlovski, Kessiakoff and ten Dam.

With one final flick of the elbow, Christophe Kern comes to an almost standstill. What an effort. His day on the front is over, now he will suffer immeasureably in the hope that Pierre Rolland can take the win.

Vino was caught by the yellow jersey group, hang on, but has now been blown out the back. Not sure if Menchov is there. Feillu has been caught and passed.

Evans and Van Garderen have caught Ivan Basso and Feillu. They only have about 10 seconds over the Sky yellow jersey group. And we still have 5km of this climb left.

Meanwhile, Kern gurns and grimaces on the front of the race. In this group there is: Rolland, Horner, P. Velits, ten Dam, Kiserlovski, Martin, Kessiakoff, Kiryienka and that man Kern. They have three minutes over Wiggins.

Evans is struggling to keep up with the pace of Van Garderen. The American opens up a few bike lengths then looks back over his shoulder and sees Evans way back down the road. Everyone is really suffering.

Thibaut Pinot is still there with the yellow jersey group. Brajkovic, van den Broeck and Menchov still there. For Sky it's Rogers, Porte, Froome and Wiggins.

Evans and Van Garderen catch Moinard, but the Frenchman cannot keep up with the pace of his BMC team mates and is dropped. They have 22 seconds on the yellow jersey group, which has been whittled down to about 10 riders now - including four Sky men.
