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.

Yellow jersey Brad Wiggins has noth Porte and Froome with him. This final climb is not too steep and shouldn't be a problem for the Brit. That final victory in Paris looks more likely by the day.

Rolland has to be the favourite of the four leaders. A stage winner last year on Alpe d'Huez, Rolland was the white jersey in Paris and could make it a double for Europcar today.

It's back together with the leaders, with Sorensen and Kiryienka joining Rolland and Kiserlovski. They still have 3:30.

The Sky machine is reeling in the remnants of the initial break - the likes of Dan Martin and Frederik Kessiakoff. And that's it for Mick Rogers - the Australian peels off, his work for the day done. Chapeau.

The yellow jersey group in full: Bradley Wiggins, Christopher Froome, Richie Porte and Michael Rogers (Sky), Cadel Evans, Tejay Van Garderen (BMC), Jurgen Van Den Broeck (Lotto), Thibaut Pinot (FDJ), Alexandr Vinokourov, Janez Brajkovic (Astana), Juan Jose Cobo Acebo (Movistar), Frank Schleck, Andreas Klöden, Haimar Zubeldia (RadioShack), Vincenzo Nibali, Ivan Basso (Liquigas), Christophe Kern (Europcar), Alejandro Valverde (Movistar), Jerome Coppel (Saur-Sojasun), Nicolas Roche (AG2R)

Sorensen and Kiryienka happy to combine together in pursuit of the two leaders. They both take a bit of time to warm up into a climb - and this is a long one. Two very different styles: the Movistar man smooth and the Saxo Banker with his shoulders rolling and swaying all over the place.

The four leaders are onto the final Cat.1 climb of La Toussuire - 18 kilometre-long climb at 6.1%. Straight away Kiserlovski makes a move and takes Rolland with him.

The four leaders are all calling for their team cars as they get themselves primed ahead of this final climb to the finish. Thibaut Pinot is just about to be caught by the yellow jersey group.

Sorensen catches the leaders and so we have four out in front now: CA Sorensen (Saxo), Rolland (Europcar), Kiserlovski (Astana) and Kiryienka (Movistar). They have just over three minutes.

Rolland is back with the other leaders, his shorts slightly torn after that fall. He gets out an energy gel. There's a bit of blood on his elbow, but otherwise he looks okay.

Robert Kiserlovski and Vasil Kiryienka lead the way, with Rolland in pursuit. The Frenchman has never been renowned for his descending - and by the looks of things he'll need to go on a downhill crash course with Sean Kelly. Chris Anker Sorensen is behind.

CRASH: Pierre Rolland takes a corner completely wrong and goes down on his left hip after unclipping his left foot from the pedal. He knew he took the wrong line and that may do his confidence a huge set back. He now has to make up the gap.

Thibaut Pinot attacks towards the summit of the Col du Mollard and crosses 10 seconds or so ahead of the yelloe jersey pack, but misses out on picking up a bidon. One absentee from the main group is Denis Menchov - the Russian clearly having an off-day.

Kessiakoff leads the mountain standings on 66 points, with Sorensen on 38 and Rolland on 35.

Pierre Rolland takes the 5 points over the summit ahead of Kiserlovski and Kiryienka. Sorensen follows a few seconds later and will no doubt catch them on the descent.

Kiryienka joins Rolland and Kiserlovski so we have three leaders now, with the ungainly Chris Anker Sorensen in pursuit. Movistar's Kiryienka loosk to be in his groove now and he's the one leading the trio.

Kiryienka is slowly returning to the leading duo of Rolland and Kiserlovski. Sorensen is a bit further back. It's touch and go for the leaders - they will be very tired by the time the final climb starts. They may not be able to withstand the onslaught that will come from behind once the GC riders start to fight.

Nibali has Basso for support now in this main group. Sky lead the way with Rogers and Froome.

Velits and Sorensen chase the two leaders, Rolland and Kiserlovski. The duo have 2:30 over the yellow jersey group, which has swelled in numbers after that descent.

Rolland has been awarded the 25 points at the top of the Croix de Fer after a rethink by the commissaires. Kessiakoff took second, but still leads the polka dot jersey standings.

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.
