If you where ever going to watch a stage of Grand Tour cycling, might I suggest tonight on SBS (in Australia of course) is the one to watch. Have a gander at this video by Dan Lloyd and you will get an idea what they are up against.

And here is a closer look at the 2 monster climbs. The Mortirolo.
My legs cramp just looking at it.
