SESTRIERE, Italy (AFP) — Alberto Contador was virtually assured of winning the Giro d’Italia for a second time after surviving attacks on yesterday’s summit finish to keep an unassailable lead on his nearest rival and stage winner Fabio Aru.

It was a second-straight stage win for 24-year-old Italian Aru, who along with teammate and third-placed overall Mikel Landa launched a desperate bid to dislodge Contador on the penultimate dirt-road climb.

But now Sunday’s flat 185 km ride into Milan means that, barring catastrophe, Spaniard Contador will roll over the finish line over two minutes ahead of Aru, adding to a first title he won there in 2008.

Current holder of the Tour of Spain title, Contador is aiming to become the first rider since the now deceased Italian Marco Pantani to achieve the Giro d’Italia-Tour de France double in the same calendar year.

“We’ll have a good dinner tonight, although I have to watch my weight for the Tour,” a light-hearted Contador said after the stage.

“This Giro d’Italia is in the bag now, with just tomorrow’s stage to come, so I’m already thinking of my next target,” he added.

The 199 km penultimate stage slog from Saint Vincent to Sestriere, featured an 8km brutal climb up the dirt roads of the Colle delle Finestre, where Astana pair Landa and Aru launched their thrilling attacks.

But Contador kept his cool to allow the pair and others to climb away from him, eventually levelling out to cross the mist-shrouded summit, where banks of snow still clung to the rocky slopes, only a minute behind then race leader Landa.

Before the final climb, Aru caught up with Landa before launching a series of attacks with 2km to go and crossed the finish line 18sec ahead of Canada’s Ryder Hesjedal.

Colombia’s Rigoberto Uran was third and Landa fourth just 24 seconds adrift.

But by this time all eyes were counting down the clock with Contador continually punching the air as he closed in on the finish line at Sestrieres knowing the title was his.

Astana’s young leader Aru is second in the overall at 2min 02sec, with his teammate Landa third at 3min 14sec, and the trio should still be in that order when the tour ends this evening.
