Today's a rest day, so let's preview stage 9. There are 4 huge climbs with the last one being labeled as No Category. The No Category label was saved for "those mountain roads where cars were not expected to be able to pass." Wiki is your friend. This stage is definitely not for babies. We will see a huge time gap between the peloton and the heavy GC favorites. Look for Contador, Schleck, Evans, and Sastre to be in that lead pack.
