PLATEAU DE BEILLE, France (AFP) — Frenchman Thomas Voeckler stubbornly held on to the Tour de France yellow jersey yesterday as reigning champion Alberto Contador survived another onslaught in the mountains.

Contador, who has complained of a sore knee, came under constant attack on the gruelling 15.8 km climb to Plateau de Beille but soaked up the pressure to lose only two seconds to key rival Andy Schleck.

“I didn’t feel great,” admitted Contador, who is still seventh overall at 4min 00sec behind Voeckler and 2:11 behind Frank Schleck.

“But as each day passes I’m feeling better.”

Belgian Jelle Vanendert, of the Omega Pharma team, meanwhile took a deserved victory on the 14th stage after jumping out of the group of overall favourites 6.8 km from the finish.

He caught early breakaway rider Sandy Casar of France and despite a late counter-attack by stage 12 winner Samuel Sanchez the Belgian held on to claim his maiden win on the race.

Vanendert finished 21sec ahead of Euskaltel rider Sanchez, with former two-time runner-up Andy Schleck coming over the line at 46, two seconds ahead of a group containing all the other yellow jersey contenders.

After their dominant Leopard-Trek team had set a demanding pace on the long flat stretch leading to the fifth and last climb of the day, Frank and Andy Schleck launched a series of small attacks in a bid to drop their rivals.

Each time, Contador and Australian Cadel Evans — as well as Italian Ivan Basso and Voeckler — were able to counter and latch back on to the group.

Only in the final 2km of the 15.8 km ascent did Andy Schleck pull away, the Luxemburger grappling just two seconds from Contador in the process.

It meant Voeckler maintained his 1min 49sec lead on Frank Schleck, with former two-time runner-up Evans still third at 2:06.

Andy Schleck, the runner-up the past two years, is fourth at 2:15 with Basso in fifth at 3:16. Contador is another 44secs off the pace in seventh.

Older brother Frank appeared to launch a veiled attack at Contador and Evans, criticising the pair for not attacking themselves.

“We tried several times. The only one who was a little bit interested was Ivan Basso,” said Frank.

Evans, whose yellow jersey bid seems to be getting stronger by the day, immediately hit back.

Voeckler meanwhile upset his own prediction that he would lose the jersey on the toughest day in the Pyrenees.

Having famously worn the yellow jersey for 10 days in 2004, Voeckler can now realistically keep it until the first of three consecutive stages in the Alps starting Tuesday.
