REVEL, France (AP) - Alexandre Vinokourov has won the 13th stage of the Tour de France in a breakaway as Andy Schleck of Luxembourg retained his 31-second lead over two-time champion Alberto Contador.
Vinokourov, a Kazakh rider who is back at the Tour after a doping ban, was fastest over five low-grade climbs during the 121-mile course from Rodez to Revel.
The top standings didn't change because the main contenders crossed in the same pack.
The race enters the Pyrenees on Sunday - the first of four days of punishing climbs in the mountains that will play a key role in who wins the three-week race at the July 25 finish in Paris.
