Quintana triumphs, Froome stays leader Colombia's Nairo Quintana celebrates as he crosses the finish line at the end of the 125 km twentieth stage of the Tour de France. Britain's Chris Froome virtually secured overall victory in the 100th Tour de France on Saturday after the 20th and penultimate stage was won by Colombian climbing specialist Nairo Quintana. Ahead of Sunday's final stage from Versailles to Paris, which is usually only disputed by the sprinters, Froome defended his significant overnight lead on the final day in the mountains. Spain's Alberto Contador, second overnight, fell off the pace on the final 10.3 km climb to Annecy-Semnoz and fell to fourth overall at 7min 10sec behind Froome. Contador's inability to follow the pace in the final five kilometres of the climb left Froome, Quintana and Joaquim Rodriguez to forge on ahead and dispute the stage victory. Froome tested his rivals with a short burst of acceleration but the Team Sky leader could not respond when Quintana pulled ahead inside the last two kilometres. Quintana went on to cross the finish line alone to claim his maiden stage win on his race debut, moving up to second overall at 5:03 behind Froome, a day before the final in Paris. Rodriguez finished 17sec adrift, but the Katusha team leader's efforts moved him up to third overall at 5:47 behind Froome. Froome's lieutenant Richie Porte finished fifth on the stage to move to 19th overall. The best-placed Australian remains Michael Rogers at 16th at 27.34. Quintana clinched the jerseys for the King of the Mountains category and best young rider. The race ends with the 21st stage on Sunday when Froome is virtually guaranteed to become the second Briton, after teammate Bradley Wiggins last year, to win the world's biggest bike race.
