Portuguese cyclist Rui Costa won Tuesday's 16th stage of the Tour de France thanks to a late breakaway.

Britain's Chris Froome retained the race leader's yellow jersey, withstanding three attacks from Spaniard Alberto Contador, the two-time Tour winner who now sits in third place, 4 minutes and 25 seconds behind the British rider.

It was the second-ever stage win in the Tour de France for Costa, 26, who rides for the Movistar team.

Costa made his move on the ascent of the Col de Manse, less than 20 kilometers (12 miles) from the finish in Gap, and no one in the lead group was capable of catching him.

While Froome was undamaged by Contador's attacks, Dutch rider Laurens ten Dam was overtaken by Costa's Colombian Movistar teammate Nairo Quintana and fell from fifth place to sixth in the general classification.

Quintana, now sporting the white jersey awarded to the best young rider in the Tour, also extended his lead in that competition to 3 minutes, 50 seconds over main rival Michal Kwiatkowski.

Wednesday's 17th Stage will feature the third and final individual time trial of the 2013 Tour de France.

The race will then move into the Alps ahead of Sunday's finale in Paris. EFE
