Welcome to live coverage of stage 11 of the Vuelta a Espana, the much anticipated 39.5km individual time trial from Cambados to Pontevedra.

Rodriguez is one second ahead of Contador, 16 seconds clear of Froome and 59 seconds ahead of Valverde. The Big Four of the Vuelta still all within one minute - fascinating.

Rordiguez's time difference to stage winner Frederik Kessiakoff was altered to 1:16, which means the Spaniard holds onto the red jersey by one slender second!

Here's Joaquim Rodriguez - he needs to finish within a minute to hold onto the red jersey. The Katusha climber has ridden out of his skin today, and crosses the line in seventh place ... 1:17 down on Kessiakoff ... and exactly a minute down on Contador!

Here comes a faltering Froome, who lost time on the climb. It's the third fastest time, ahead of Valverde, but below his rival Contador. It's 39 seconds down on Kessiakoff, the stage winner.

Alejandro Valverde rode brilliantly to take provisional third, 1:08 down on Kessiakoff. Just two more riders to arrive - Froome and Rodriguez.

Here comes Alberto Contador... it's a great ride, but not enough to take the win: he's 17 seconds down on Kessiakoff, who looks to have become the surprise winner of today's time trial.

Robert Gesink crosses the line to take eighth place, 1:42 down on Kessiakoff. That should be enough to keep him in the top ten, for sure.

The upper hand is definitely with Contador in his duel with Froome - the latest check is 26 seconds, the Sky rider clearly feeling his travails from the Tour.

Rodriguez is still only 49 seconds down on Contador as he limits his losses on this descent. He's riding a very good time trial and will be well within contact of the summit tonight.

Contador is gaining time on Froome on the descent - he's 20 seconds ahead now.

Alejandro Valverde was only 37 seconds down on Kessiakoff at the second check - the time gaps are not as big as we had expected.

Joaquim Rodriguez is 56 seconds down on Frederik Kessiakoff at the first check, so that's 54 down on Contador, who is not yet the virtual red jersey on the road.

Chris Froome is slipping: the Briton is 18 seconds down on Kessiakoff at the second check after the climb, which puts him 16 down on Contador, who will probably be in the red jersey tonight.

Alberto Contador can only post the second fastest time at the second check - two seconds down on Kessiakoff.

Gesink has faded on the climb - the Dutchman sets only the 10th fastest time at the second check, more than a minute down.

Andrew Talansky crosses the finish to set the fifth best time, 1:24 down on Kessiakoff of Sweden.

Contador is really giving it his all. At the moment, he's four seconds faster than his rival Froome - who he is racing for the first time in Spain.

Benat Intxausti (Movistar) set the second best time at the finish, 1:09 down on currently leader Kessiakoff.

Eurosport commentator Dave Harmon: "I think Froome looks a little more laboured than Contador - not much, but a little more."

Purito looks in a bit of discomfort. He's out of the saddle and has his mouth agape. Today is all about survival - he knows the mountains are better suited to his strengths and so will want to be in touch with the summit after today's test.
