Just went to the website and reviewed the stages. Stage 6, Park City has an official 3,051' (10,009m) of climbing. That's quite a discrepancy! (Home field advantage? Place a divider in the road. Those who do feet and inches, go right, those who do metric go left. The American riders arrive at the finish fresh as daisies, the rest days later.}
They swapped the feet and meters. Oops.
So the Prologue has started. Race on! And with ~600' of climbing in 2 miles, we should see difference bigger than sprint bonuses.
