Alexandre Vinokourov (Astana) charged back into overall contention in the Tour de France on Saturday by dominating the 54km time trial around Albi and pulling back huge chunks of time on all his big rivals.

Australia?s Cadel Evans (Predictor) was second, 1-14 slower than Vino and stopped an Astana one-two-three, but it was a scary performance from the boys in sky blue, with Andreas Kloden third at 1-39 and Andrey Kashechkin fourth at 1-44.

Michael Rasmussen rode what he described as the time trial of his life to keep the race leader?s yellow jerse but is only a minute ahead of Cadel Evans.Kloden is now fourth overall, 2-34 behind Rasmussen, Kashechkin is sixth at 4-23 and Vinokourov is ninth at 5-10. With Alejandro Valverde, Iban Mayo and Carlos Sastre struggling in the time trial, all three Astana riders are capable of winning the Tour de France, and with a combined team strategy, they could blow the race apart in the Pyrenees in the next few days.

Rasmussen tried to enjoy his best ever time trial performance but clearly knows he is racing under a dark cloud of doping suspicion.

He dismissed the problem of missed doping tests as an ?administrative error? but absolutely refused to answer questions about the accusations made by an American mountain biker Whitney Richards, who claimed in US magazine Velonews that Rasmussen asked him to transport performance-enhancing bovine haemoglobin to Italy in a shoe box in 2002.

WIGGINS FIFTH

Britain?s Bradley Wiggins (Cofidis) finished fifth in the time trial, 2:14 behind Vino after topping the leader board for most of the stage. Wiggins had the fortune of racing half of the rolling course in the dry conditions but produced a determined ride.

?I didn’t expect much but had a great day. I went out and hurt myself. I?m pretty tired because we?re two weeks into the Tour now but I?m used to being in pain every day. Today it was a nice pain, that made me want more of it,? wiggins said.

David Millar (Saunier Duval) finished 1-13 behind Wiggins but was happy to race in the rain after struggling with a sun allergy in recent days. Welshman Geraint Thomas ?the youngest rider in this year?s Tour de France, also impressed, finishing 52nd. Charly Wegelius was 104th at 8-37 as he saved his legs for the three tough days in the Pyrenees.
