Ok, a couple of things:
1. Who are the true climbers in the TDU?
Valverde, Gerrans, Meyer?
Why hasn't LL Sanchez shown himself?
Will Tiago Machado come through?
Will Sandy Casar give it a go?
Can Boassen hang?
2. What's Willunga Hill going to do to the GC?
How long is it?
What will the time gaps be?
