At only about 13 minutes of climb time, Altos Cumbres Verdes is a bit short to use the pVAM model. But it is still somewhat illustrative to take a look at how the performance estimates compare to the 2008-2013 reference range.
The raw nW/kg estimates came in between 6.4-6.5 nW/kg. Since this was a relatively low altitude climb the power comes down to 6.3-6.4 naW/kg when normalized for altitude for sake of the historical comparison.
From this first climb it does look like the favorites are on good (especially considering the heat) but no necessarily shocking form. We may just get the Froome Contador battle hoped at the TDF as both Froome and Contador likely to ride into form as the race progresses. Look for Quintana to bounce back on stage 9 as altitude will be a bit more of a factor.
