San Jose - Mount Diablo 174.5 km
First of the two mountaintop finishes, just as last year on Mt Diablo. Not the worst of climbs but with Wiggins so firmly in the lead the climbers really need to make the most of every meter of climbing.
Little Leipheimer Californian Achiever: Janier Acevedo
Speaking of needing to make up time..... Acevedo had his breakthrough here a year ago, can he take another step up?
