As the first rest day approaches Porte sits third overall, 22 seconds behind race leader Alberto Contador (Tinkoff-Saxo) with Astana's Fabio Aru separating them, three seconds off the Maglia Rosa.
Significantly, Porte has been able to respond to the attacks of his rivals, has avoided crashes and has support from him Sky team-mates in the mountains.
“He’s been perfectly placed, he hasn’t put a foot wrong. He’s been at the right wheel at the right time and he’s never had to go into the red all week. Strategically he’s ridden a fantastic race so far." - Dave Brailsford.
@richie_porte: Long, hard day on the bike followed by a nice transfer. Now bring on the rest day!
Brailsford is hoping that the team's patient approach to the Italian Grand Tour will pay dividends in Milan on 31 May.
“It’s been a very good nine stages for us, a stage win - very good - we’ve got the red jersey and we’ve come here to play the long game," Brailsford told Cyclingnews.
“From experience we came into this Grand Tour maybe thinking about it slightly differently to others, biding our time and being a bit more patient and strategic and using the fact that Astana and Tinkoff-Saxo are very strong and we can ride off that for the time being.
“We are keeping our heads down, keeping out of trouble and staying well-positioned. And we’re pretty happy with that.”
Looming on the horizon is the Stage 14 individual time trial from Treviso to Valdobbiadene. At 59.4km long it will have a significant impact on the overall standings.
“As that time trial is looming, you’ve got to think about it," continued Brailsford. "But you’ve got to be careful it doesn’t start to cloud your thinking. From our point of view we’ll just take it on the stage by stage and bide our time.
“There haven’t been any significant time differences yet, but we do know that there will be then in the time trial, positive or negative. That’s going to happen. How, though, we don’t know yet.”
