TASMANIAN Richie Porte says the next two days in the Alps could shape the rest of the Tour De France as he prepares his attack on yellow jersey-holder Vincenzo Nibali.
Astana rider Nibali is still two minutes, 23 seconds ahead of the Team Sky leader after 185.5km stage 12 of the Tour de France from Bourg-en-Bresse to Saint Etienne.
But Porte (pictured, inset) said the next two stages (starting overnight) could be crucial come the end of the big race.
"It's not an easy two days coming up," Porte admitted. "I think it's going to be absolutely crucial for the general classification, so I'm looking forward to taking more time on the guys behind me."
Norway's Alexander Kristoff (pictured, left)) won a sprint finish to claim yesterday's stage following a breakaway from Australia's Simon Clarke with 26km remaining.
The Orica-GreenEDGE rider was eventually caught on the descent into Saint Etienne before the peloton closed in and Kristoff pulled away for glory.
